TL; DR: Top Five Rookie Mistakes by Self-Proclaimed Scrum Masters Are you struggling with imposter syndrome as a new Scrum Master? Avoid five common rookie mistakes Scrum Masters make. Instead, discover how to set clear Sprint Goals, build trust, balance metrics, and empower your team to make independent decisions. Don’t let early missteps define your journey. Learn from these mistakes and transform them into stepping stones towards mastery. By understanding and addressing these pitfalls, you’ll gain confidence, enhance your leadership skills, and truly embody the principles of Scrum. This article provides actionable insights and practical exercises to help you grow from a beginner into an effective and respected Scrum Master. Rookie Mistakes Scrum Masters Make Let us delve into the rookie mistakes Scrum Masters make: 1. Ignoring the Importance of the Sprint Goal Mistake: Treating the Sprint Goal as optional or just a list of tasks, leading to a lack of focus and direction for the Scrum Team Why it’s a mistake: The team lacks a unified purpose without a clear Sprint Goal, resulting in fragmented efforts, reduced overall value delivery, and difficulty measuring success. The team may become directionless, working on tasks that don’t align with the Product Goal or the strategic objectives of the product generally. Learning opportunity: Legitimate beginners quickly realize the importance of a well-defined Sprint Goal as a beacon guiding the team’s efforts. It fosters collaboration and ensures that the team delivers meaningful value each Sprint. To practice this, try a Sprint Goal workshop before the next Sprint, where the team collaborates to draft a clear, cohesive goal. 2. Micromanaging the Team Mistake: Acting as a task or project manager, constantly overseeing and directing the work of the Developers Why it’s a mistake: Scrum Masters should serve the team by removing impediments and facilitating processes, not controlling the work as the Developers have agency doing their part. Micromanagement stifles team autonomy and innovation, leading to reduced morale and a lack of ownership among team members, ultimately hampers productivity and creativity. Learning opportunity: True beginners learn to trust their team’s capabilities, focusing instead on enabling the team to self-organize and resolve issues independently, leading to higher engagement and better problem-solving. An exercise to help with this is to restrain from solving issues during a Sprint but observe and support their teammates’ progress. 3. Neglecting To Build Team Trust and Psychological Safety Mistake: Failing to create an environment of trust and psychological safety where all team members feel comfortable sharing ideas and concerns Why it’s a mistake: Without trust and safety, team members are less likely to engage fully, collaborate effectively, or take risks. Neglecting trust stifles innovation and continuous improvement, leading to a work environment with undisclosed problems, lackluster team engagement, and restrained creativity. It can also result in high turnover and low job satisfaction. Learning opportunity: Proficient Scrum Masters actively work to build and maintain a culture of trust and psychological safety. They encourage open communication and constructive feedback. A practical exercise is to hold regular team-building activities and trust exercises, such as sharing personal success stories, challenges, and failures to build empathy and understanding among team members. 4. Focusing Solely on Metrics and Reporting Mistake: Overemphasizing metrics, OKRs, and KPIs, turning the Scrum Master role into a data-entry clerk burdened with excessive reporting Why it’s a mistake: While metrics can provide valuable insights, overemphasis can distract from the true purpose of Scrum, which is delivering value through collaborative efforts and continuous feedback based on frequent releases and an empirical process. A metrics-driven approach can also lead to gaming the system, where team members focus on meeting the metrics rather than creating genuine value, thus distorting the team’s priorities. Learning opportunity: Effective Scrum Masters balance metrics with qualitative insights, using them to support, not dictate, team decisions and progress. They understand that metrics are tools, not goals in themselves. An exercise to implement this is to periodically review the metrics with the team, discussing their relevance and how they align with actual value delivery, ensuring a balanced approach. 5. Failing To Empower the Team Mistake: Not empowering the team to make decisions and solve problems, often stepping in to make decisions or resolve conflicts Why it’s a mistake: This approach undermines the team’s confidence and ability to self-manage, leading to dependency on the Scrum Master and reduced team ownership of the work. It hampers the team’s growth, creativity, and innovation ability, as members are not encouraged to think independently or take initiative. Learning opportunity: Good Scrum Masters learn to step back and facilitate the team’s decision-making processes, encouraging team members to take ownership of their work and develop their problem-solving skills. A helpful exercise is to use a decision matrix, for example, based on the outcome of a Delegation Poker session, where the team collaboratively decides on solutions to issues without direct intervention from the Scrum Master, promoting autonomy and confidence. Useful Practices for Beginners To Avoid Rookie Mistakes Scrum Masters Make Some food for thought for the aspiring learner: there is no need for you to reinvent the wheel. Embrace Continuous Learning Scrum Masters should always be on a path of continuous learning. Scrum and agile practices evolve, and so should your understanding and application of them. Seek opportunities for training, certifications, and networking with other Scrum professionals. For example, join the Hands-on Agile Slack community or our Meetup group. Understand the Organizational Context Every organization has its unique culture and challenges. Understanding the broader context within which your team operates can help you better support and advocate for Scrum practices. Engage with stakeholders and management to align Scrum with organizational goals. Remember, you cannot change a system at the Scrum team level. Balance Empathy With Accountability Building a high-performing team requires a delicate balance of empathy and accountability. While fostering a supportive environment is crucial, holding the team accountable to commitments and quality standards is equally important. Great Scrum teams hold themselves accountable all the time; they are professionals. Be a Servant Leader As a Scrum Master, your primary role is to serve the team, for example, by removing impediments, facilitating communication, and supporting the team’s self-organization. The team’s success measures your success, so focus on empowering them. Adaptability Is Key No two teams are the same, and what works for one might not work for another. Be flexible and willing to adapt your approach based on the team’s needs and feedback. Continuously inspect and adapt not just the team’s processes but your own practices and mindset. Foster a Growth Mindset Encourage a culture where failure is seen as an opportunity to learn and grow. Coupled with a growth mindset, it can significantly enhance the team’s ability to innovate and improve continuously. Celebrate successes but also openly discuss failures and the lessons learned from them. Value Feedback Loops Feedback is the cornerstone of continuous improvement. Make sure your team regularly seeks and gives feedback, not just during formal events like Sprint Reviews and Retrospectives but also in daily interactions. Feedback taken seriously will help identify issues early and promote a culture of transparency and improvement. Conclusion The critical difference between the rookie mistakes of the ignorant imposter and the actions of a learning beginner is the willingness to reflect, adapt, and grow from experiences. Self-proclaimed experts who misunderstand and, consequently, misapply the principles of Scrum fail to recognize and rectify their mistakes. At the same time, true beginners use these early missteps as stepping stones toward becoming effective and respected Scrum Masters.
A (long) time ago, my first job consisted of implementing workflows using the Staffware engine. In short, a workflow comprises tasks; an automated task delegates to code, while a manual task requires somebody to do something and mark it as done. Then, it proceeds to the next task — or tasks. Here's a sample workflow: The above diagram uses the Business Process Model and Notation. You can now design your workflow using BPMN and run it with compatible workflow engines. Time has passed. Staffware is now part of Tibco. I didn't use workflow engines in later jobs. Years ago, I started to automate my conference submission process. I documented it in parallel. Since then, I changed the infrastructure on which I run the software. This post takes you through the journey of how I leveraged this change and updated the software accordingly, showcasing the evolution of my approach. Generalities I started on Heroku with the free plan, which no longer exists. I found that the idea was pretty brilliant at the time. The offering was based on dynos, something akin to containers. You could have a single one for free; when it was not used for some time, the platform switched it off, and it would spin a new one again when receiving an HTTP request. I believe it was one of the earliest serverless offerings. In addition, I developed a Spring Boot application with Kotlin based on the Camunda platform. Camunda is a workflow engine. One of the key advantages of workflow engines is their ability to store the state of a particular instance, providing a comprehensive view of the process. For example, in the above diagram, the first task, labeled "Request Purchase," would store the requester's identity and the requested item (or service) references. The Purchase Department can examine the details of the requested item in the task after. The usual storage approach is to rely on a database. The Initial Design At the time, Heroku didn't provide free storage dyno. However, I had to design my initial workflow around this limitation, which posed its own set of challenges. I couldn't store anything permanently, so every run had to be self-contained. My fallback option was to run in memory with the help of H2. Here is my initial workflow in all its glory: As a reminder, everything starts from Trello. When I move a card from one lane to another, Trello sends a request to a previously registered webhook. As you can expect, the hook is part of my app and starts the above workflow. The first task is the most important one: it evaluates the end state from the event payload of the webhook request. The assumption is that the start state is always Backlog. Because of the lack of storage, I designed the workflow to execute and finish in one run. The evaluation task stores the end state as a BPMN variable for later consumption. After the second task extracts the conference from the Trello webhook payload, the flow evaluates the variable: it forwards the flow to the state-related subprocess depending on its value. Two things happened with time: Salesforce bought Heroku and canceled its free plan. At the same time, Scaleway offered their own free plan for startups. Their Serverless Container is similar to Heroku's - nodes start when the app receives a request. I decided to migrate from Heroku to Scaleway. You can read about my first evaluation of Scaleway. I migrated from H2 to the free Cockroach Cloud plan Refactoring to a New Design With persistent storage, I could think about the problems of my existing workflow. First, the only transition available was from the Backlog to another list, i.e., Abandoned, Refused, or Accepted. The thing is, I wanted to account for additional less-common transitions; for example, the talk was accepted but could be later abandoned for different reasons. With the in-place design, I would have to compute the transition, not only the target list. Next, I created tasks to extract data. It was not only unnecessary, it was bad design. Finally, I used subprocesses for grouping. While not an issue per se, the semantics was wrong. With persistent storage, we can pause a process instance after a task and resume the process later. For this, we rely on messages in BPMN parlance. A task can flow to a message event. When the task finishes, the process waits until it receives the message. When it happens, the flow process resumes. If you can send different message types, an event-based gateway helps forward the flow to the correct next step. Yet, the devil lurks in the details: any instance can receive the message, but only one is relevant — the one of the Trello card. Camunda to the rescue: we can send a business key, i.e., the Trello card ID, along with the message. Note that if the engine finds no matching instance, it creates a new one. Messages can trigger start events as well as regular ones. Here's my workflow design: For example, imagine a Trello hook that translates to an Abandoned message. If there's no instance associated with the card, the engine creates a new instance and sends the Abandoned message, which: Start with the flow located at the lower left Ticks the due date on the Trello card Finishes the flow If it finds an existing instance, it looks at its current state: it can be either Submitted or Accepted. Depending on the state, it continues the flow. Conclusion In this post, I explained how I first limited my usage of BPMN and then unlocked its true power when I benefited from persistent storage. However, I didn't move from one to the other in one step. My history involves around more than twenty versions. While Camunda keeps older versions by design, I didn't bother with my code. When I move them around, it will fail when handling cards that were already beyond Backlog. Code needs to account for different versions of existing process instances for regular projects. I'm okay with some manual steps until every card previously created is done. To Go Further Business Process Model and Notation Camunda My evaluation of the Scaleway Cloud provider

In today's rapid product landscape, innovation occurs at lightning speed. Product Managers are in perpetual pursuit of innovation, launching products, seizing new markets, and fueling growth. Building something innovative that can transform a customer’s journey, enhance their daily lives, boost productivity, or provide entertainment is exhilarating. However, what happens when the job is not as glamorous or thrilling, such as phasing out a product? How do you inspire your team to embrace the mission of gracefully retiring the product? The decision to discontinue a product is a crucial one, and when handled with care, it can preserve customer relationships, minimize disruption, and ensure a smooth transition. In this comprehensive guide, we'll explore the key steps and considerations for product managers when it's time to say goodbye to a product. The Need for Sunsetting Sunsetting a product, which refers to the process of phasing out or discontinuing a product or service, is often a necessary decision for several reasons: Technological advancements: As technology evolves, older products may become obsolete. Sunsetting allows a company to focus on newer, more advanced offerings that better meet current market demands. Resource allocation: Maintaining and supporting aging products can be resource-intensive. By discontinuing them, a company can reallocate resources—like time, money, and people — to newer and more innovative initiatives that meet the current market demand. Market changes: Consumer preferences and market trends can shift rapidly. Sunsetting a product that no longer aligns with these trends ensures that a company remains relevant and competitive. Quality and reputation: Older products that are no longer up to current standards can harm a company's reputation. Sunsetting such products can help maintain a brand's image for quality and innovation. Cost efficiency: As products age, they may become more expensive to maintain and support, especially if they require unique or outdated technology. Sunsetting can be a cost-effective decision. Regulatory compliance: New regulations or changes in compliance standards can render some products non-compliant. Sunsetting is a necessary step to adhere to these legal requirements. Strategic focus: Companies often refine their strategic direction to meet the needs of customers and stay ahead of their competitors. Sunsetting products that don't align with the new strategic goals allows a business to stay focused and efficient. User experience: Phasing out older products can also be a part of enhancing the overall user experience, pushing customers towards better, more efficient, and feature-rich alternatives. When executed well, sunsetting enables companies to reallocate resources to more promising areas, enhancing their competitiveness and capacity for innovation. This decision, while difficult, is pivotal for maintaining a robust, relevant product portfolio aligned with long-term organizational goals. Overall, sunsetting a product is a strategic move to optimize a company's portfolio, ensuring it stays innovative, relevant, and financially sound. Key Considerations for Product Managers When Sunsetting a Product 1. Impact Assessment Impact assessment, which is a critical first step, involves a thorough evaluation of sunsetting's potential consequences. One would need to analyze how sunsetting affects current users, revenue streams, and the company's brand reputation. While sunsetting a product, one must consider both short-term and long-term impacts on customer trust and the company's market position. This assessment forms the foundation for making an informed decision. 2. Sunsetting Timeline Crafting a detailed and realistic timeline is vital for a smooth transition. This timeline should cover all phases of sunsetting: initial planning, stakeholder notification, support period, and final closure. It's crucial to provide adequate time for customers and internal teams to adapt, and to anticipate potential delays or issues. 3. Stakeholder Communication and Transparency Clear, timely, and empathetic communication with stakeholders is key to managing expectations and maintaining trust. Transparency about the reasons for sunsetting, its benefits, and its impacts is essential in managing the narrative and reducing backlash. Regular updates can keep stakeholders informed and engaged throughout the process. 4. Data-Driven Decision-Making Sunsetting decisions should be rooted in solid data analysis. Examine customer engagement metrics, support requests, financial performance, and market trends. This data-driven approach helps understand the product's actual usage and viability, providing a rational basis for decision-making and supporting internal and external communication. 5. Customer Transition Planning Developing a comprehensive plan for customer transition is critical. This includes offering alternatives or upgrades, migration assistance, and robust customer support during the transition. Effective communication of these plans minimizes customer inconvenience and dissatisfaction, bolstering customer loyalty and relationships. 6. Resource Allocation Strategically reallocating resources, both human and financial, is a key aspect of sunsetting a product. Consider how to best invest these resources—whether in developing new products, enhancing existing ones, or exploring new market opportunities. This can transform the sunsetting of one product into a growth opportunity for other areas. 7. Legal and Regulatory Compliance Ensuring legal and regulatory compliance is paramount when sunsetting a product. This includes honoring existing contracts and agreements, managing data privacy concerns, and adhering to industry-specific regulations during the sunsetting process. Communicating legal implications to stakeholders, particularly regarding data handling and service commitments, is also vital. Case Study: Sunsetting at Amazon Take Amazon for an example. Known for its innovation, Amazon has occasionally sunsetted products as part of its strategic approach. One notable example is the Amazon Dash, a Wi-Fi device for repeat purchases. Despite being a technological advancement, the Dash faced regulatory challenges, especially in the EU, and was ultimately discontinued. Taking the key considerations listed in the previous sections and reflecting on how Amazon applied them to the discontinuation of its Dash product: 1. Customer and Market Impact Amazon evaluated Dash's market performance and regulatory challenges, particularly in Germany, which impacted longer-term viability and survival of the product. 2. Financial Considerations The cost of maintaining the Dash, given regulatory issues and the emergence of alternative technologies (like Echo), likely influenced its sunset. 3. Communication Strategy Amazon's shift from Dash to other products would have involved strategic communication through marketing channels, customer support channels, and sales channels to minimize customer disruption. Amazon would have also had to involve its legal team with any kind of legal and privacy challenges in terms of customer data. 4. Marketing and Customer Touchpoints Transitioning customers from Dash to other Amazon services like Echo would have been a key focus, ensuring a smooth shift in consumer behavior. 5. Financial Strategies and Incentives Phasing out Dash possibly involved financial considerations like the cost-benefit analysis of maintaining the product versus investing in more advanced technologies. In essence, Amazon's decision to sunset Dash was likely driven by a combination of market dynamics, regulatory challenges, strategic realignment towards more advanced technology, and a focus on long-term profitability over short-term gains. The company's emphasis on “Ownership” where leaders focus on longer-term value instead of short-term results often guides these decisions. This approach reflects Amazon's broader strategy of spreading investments across various sectors and leveraging technology for competitive advantage. Conclusion Sunsetting a product is a complex, yet strategic process, essential for aligning resources with market needs and organizational goals. It encompasses thorough impact assessment, detailed planning, transparent communication, data-driven decision-making, careful customer transition, wise resource allocation, and legal compliance. Though challenging, it's a vital part of the product lifecycle that, when managed thoughtfully, leads to innovation, growth, and a more focused product portfolio. For product managers, mastering the art of sunsetting is not just about ending a product's journey; it's about transforming challenges into opportunities for future success.
Executive engineers are crucial in directing a technology-driven organization’s strategic direction and technological innovation. As a staff engineer, it is essential to understand the significance of executive engineering. It goes beyond recognizing the hierarchy within an engineering department to appreciating the profound impact these roles have on individual contributors’ day-to-day technical work and long-term career development. Staff engineers are deep technical experts who focus on solving complex technical challenges and defining architectural pathways for projects. However, their success is closely linked to the broader engineering strategy set by the executive team. This strategy determines staff engineers' priorities, technologies, and methodologies. Therefore, aligning executive decisions and technical implementation is essential for the engineering team to function effectively and efficiently. Executive engineers, such as Chief Technology Officers (CTOs) and Vice Presidents (VPs) of Engineering, extend beyond mere technical oversight; they embody the bridge between cutting-edge engineering practices and business outcomes. They are tasked with anticipating technological trends and aligning them with the business’s needs and market demands. In doing so, they ensure that the engineering teams are not just functional but are proactive agents of innovation and growth. For staff engineers, the strategies and decisions made at the executive level deeply influence their work environment, the tools they use, the scope of their projects, and their approach to innovation. Thus, understanding and engaging with executive engineering is essential for staff engineers who aspire to contribute significantly to their organizations and potentially advance into leadership roles. In this dynamic, the relationship between staff and executive engineers becomes a critical axis around which much of the company’s success revolves. This introduction aims to explore why executive engineering is vital from the staff engineer’s perspective and how it shapes an organization's technological and operational landscape. Hierarchal Structure of Engineering Roles In the hierarchical structure of engineering roles, understanding each position’s unique responsibilities and contributions—staff engineer, engineering manager, and engineering executive—is crucial for effective career progression and organizational success. Staff Engineers are primarily responsible for high-level technical problem-solving and creating architectural blueprints. They guide projects technically but usually only indirectly manage people. Engineering Managers oversee teams, focusing on managing personnel and ensuring that projects align with the organizational goals. They act as the bridge between the technical team and the broader business objectives. Engineering Executives, such as CTOs or VPs of Engineering, shape the strategic vision of the technology department and ensure its alignment with the company’s overarching goals. They are responsible for high-level decisions about the direction of technology and infrastructure, often dealing with cross-departmental coordination and external business concerns. The connection between a staff engineer and an engineering executive is pivotal in crafting and executing an effective strategy. While executives set the strategic direction, staff engineers are instrumental in grounding this strategy with their deep technical expertise and practical insights. This collaboration ensures that the strategic initiatives are visionary and technically feasible, enabling the organization to innovate while maintaining robust operational standards. The Engineering Executive’s Primer: Impactful Technical Leadership Will Larson’s book, The Engineering Executive’s Primer: Impactful Technical Leadership, is an essential guide for those aspiring to or currently in engineering leadership roles.

Joining the Agile framework provides access to resources and support that can help your organization maximize the benefits of Agile. It also provides a platform to connect with other Agile practitioners to share best practices and learn from each other. Practicing Agile working methods allows teams to pursue their goals at their own pace and with as much creativity as they want, and they're also a great way to bond as a team. Agile teams are also better able to respond to changes in the market quickly and efficiently, which is essential for success. Agile teams also tend to be more motivated, as they feel they are in control of their destiny. So, if you are wondering how to encourage your team to embrace Agile values and principles, Agile games are one of the best options to get started with. What Are Agile Games? A major benefit of Agile games is that they support team building through new learning activities and iteration. As a result, Agile games support the communication and self-organization capabilities of DevOps teams. As a result, your team members will be better able to learn Agile software more rapidly. This will lead to better collaboration between teams, more efficient development, and faster time to market. Agile games also help teams to identify potential risks and issues early in the development process. This allows them to quickly adjust and course-correct as needed. Agile games also help teams build trust, foster collaboration and encourage creativity. This in turn leads to better problem-solving, increased team morale, and a greater sense of ownership. What Agile Games Are Best for Team Building? Here you can find some of the best Agile games that help boost team effort and support. Murder Mystery Play murder mystery games to boost team communication and thinking skills. Participants need to work together to solve the case and uncover the murderer. The game encourages collaboration and creativity as players need to think outside the box and come up with unique solutions. It also tests participants' problem-solving skills and their ability to think critically. The Paper Airplane Another great Agile game is the paper airplane game, and it can be played by any team. As a basic premise, each member of your team must construct a paper airplane. The catch is that each member is only permitted to fold the plane one time before handing it over to the next member. In addition to increasing team bonding, this is an effective way to teach team members how their contributions contribute to the project as a whole. Ball Point This ball-based game follows the same principles as most Agile games, in which team members communicate and formulate strategies. The game consists of teams passing a ball around, and each time a member touches the ball, a point is scored, but points are accumulative when the last member touches the ball and is also the first one to touch it. Marshmallow Tower A marshmallow serves as the crown of a tower in this game. As simple as it may sound, the "building materials" given to teams are often fairly flimsy; spaghetti, for instance, or even string have been used as "building materials" in Agile games. This is another great Agile game for teaching teams agility since it rewards the team with the most structurally sound marshmallow tower, although speed and specifications are also important factors. Chocolate Bar A great way to get a better understanding of iterations and customer feedback for teams is through this game. It can be played in person, or with a Miro board. Your goal is simple (and delicious): you are building a chocolate bar based on customer input. One person will be designated to perform the role of the product manager or product owner, and everyone else will serve as a customer. The Emoji Game This emoji game is an excellent way to facilitate communication when it comes to Agile games. Team members must interpret what the messenger means by using emojis. The catch is that the messenger can only communicate using emojis. A favorite film or album, for example, or a message describing the messenger's characteristics might be appropriate. Conclusion These are the best Agile games for team building as they provide moral support and better communication and delivery skills. Team mates can collaborate more in a better way to solve the game and that also helps them boost These games also help increase the morale of the team and build trust between the team members. They can also help in creating better problem-solving skills and critical thinking. Lastly, these Agile games can help in breaking the monotony of the workplace and having fun while working together.
In today's dynamic business landscape, where retailers, banks, and consumer-facing applications strive for excellence and efficiency in customer support, the reliance on tools like JIRA for project management remains paramount. However, the manual creation of tickets often results in incomplete information, leading to confusion and unnecessary rework, particularly in sectors where live chatbots play a crucial role in providing real-time support to end-users. In this article, we'll explore how AI chatbots, powered by large language models, can streamline manual ticket creation. With artificial intelligence in play, businesses can reshape their project management strategies and deliver flawless customer support experiences. Solution The proposed solution will leverage ChatGPT, a large language model from OpenAI. We are going to leverage LangChain, an open-source library to facilitate the smooth integration with OpenAI. Please note that you can also leverage Llama2 models with LangChain for this use case. Figure 1: Leveraging LLM-enabled chatbot The solution components include: LangChain agents: The fundamental concept behind agents involves using a language model to decide on a sequence of actions. Unlike chains, where actions are hardcoded into the code, agents utilize a language model as a reasoning engine to ascertain which actions to execute and in what sequence. Tools: When constructing the agent, we will need to provide it with a list of tools that it can use. We will create a custom tool for Jira API. Chat memory: LangChain agents are stateless they don't remember anything about previous interactions. Since we want the AI model to collect all the relevant information from the user before creating the JIRA ticket we need the model to remember what the user provided in the previous conversation. Installing LangChain Let's first install all the dependencies: Python pip install langchain-openai langchain atlassian-python-api -U Let's set the environment variables: Python import os os.environ["JIRA_API_TOKEN"] = "<jira_api_token>" os.environ["JIRA_USERNAME"] = "<jira_username>" os.environ["JIRA_INSTANCE_URL"] = "<jira_instance_url>" os.environ["OPENAI_API_KEY"]= "<open_api_key>" Now, let's initialize the model. For this article, we will leverage OpenAI models. Python from langchain_openai import ChatOpenAI llm = ChatOpenAI(model="model-name", temperature=0) Creating Tools We will define the input schema using the Pydantic Python library. Pydantic is a data validation and settings management library in Python that is widely used for defining data models. Pydantic guarantees that input data conforms to specified models, thereby averting errors and discrepancies. It aids in generating documentation from field descriptions, thereby enhancing comprehension of data structures. Let's take a look at the schema defined using the Pydantic Python library: Python from langchain.pydantic_v1 import BaseModel, Field from typing import List, Optional, Type class TicketInputSchema(BaseModel): summary: str = Field(description="Summary of the ticket") project: str = Field(description="project name", enum=["KAN","ABC"]) description: str = Field(description="It is the description of the work performed under this ticket.") issuetype: str = Field(description="The issue type of the ticket ", enum=["Task", "Epic"]) priority: Optional(str) = Field(description="The issue type of the ticket ", enum=["Urgent", "Highest","High", "Low", "Lowest"]) Based on the code summary above, project, description, and issue type are required while priority is optional. This @tool decorator is the simplest way to define a custom tool. The decorator uses the function name as the tool name by default, but this can be overridden by passing "ticketcreation-tool" as our tool name. We will pass the args_schema as TicketInputSchema as defined above using Pydantic. This will force the language model to first ensure the schema is validated before proceeding with tool invocation. Additionally, we will include a docstring to help the language model understand the purpose of this tool and the expected output structure. We will leverage JiraAPIWrapper provided by LangChain, which is a class that extends BaseModel and is a wrapper around atlassian-python-api. The atlassian-python-api library provides a simple and convenient way to interact with Atlassian products using Python. Python from langchain.utilities.jira import JiraAPIWrapper Let's look at the complete code: Python @tool("ticketcreation-tool", args_schema=TicketInputSchema) def ticketcreation( summary: str, project: str, description: str, issuetype: str, priority: str) -> dict: """ This tool is used to create a jira issue and returns issue id, key, links""" import json payload = json.dumps({ "project": { "key": project }, "summary": summary, "description": description "issuetype": { "name" : "Task" }, "priority": { "name": priority }, # "custom_field_10010":{ # "value": impact # } }) response = JiraAPIWrapper().issue_create(payload) return response We will use the code below to bind the tools with the model: Python tools = [ticketcreation] llm_with_tools = llm.bind(tools) Memory Management This solution will leverage ConversationBufferMemory. Python from langchain.memory import ConversationBufferMemory memory = ConversationBufferMemory(memory_key="history", return_messages=True) Defining the Prompt In a LangChain OpenAI prompt, system messages offer context and instructions, followed by placeholders for user input and agent scratchpad. The system message component in the prompt lets the model know the context and provides guidance. Here is a sample system message that I have used: Python ( "system", """ You are skilled chatbot that can help users raise Jira tickets. Ask for the missing values. Only Allow values from allowed enum values """, ) Our input variables will be limited to input, agent_scratchpad, and history. input will be provided by the user during invocation, containing instructions for the model. agent_scratchpad will encompass a sequence of messages containing previous agent tool invocations and their corresponding outputs. history will hold interaction history and generated output. Here is a sample history object: [HumanMessage(content='Can you help me create a jira ticket'), AIMessage(content='Sure, I can help with that. Please provide me with the details for the Jira ticket you would like to create.')], 'output': 'Sure, I can help with that. Please provide me with the details for the Jira ticket you would like to create.'} And here is the prompt code using ChatPromptTemplate: Python from langchain_core.prompts import ChatPromptTemplate, MessagesPlaceholder prompt = ChatPromptTemplate.from_messages( [ ( "system", """ You are skilled chatbot that can help users raise jira tickets. Ask for the missing values. Only Allow values from allowed enum values. """ ), MessagesPlaceholder(variable_name="history"), ("user", "{input}"), MessagesPlaceholder(variable_name="agent_scratchpad"), ] ) Agent Pipeline This pipeline represents the sequence of operations that the data goes through within the agent. The pipeline below is defined using the pipeline operator "|" which ensures that the steps are executed sequentially. Python from langchain.agents.format_scratchpad.openai_tools import format_to_openai_tool_messages from langchain.agents.output_parsers.openai_tools import OpenAIToolsAgentOutputParser agent = ( { "input": lambda x: x["input"], "agent_scratchpad": lambda x: format_to_openai_tool_messages( x["intermediate_steps"] ), "history": lambda x: x["history"], } | prompt | llm_with_tools | OpenAIToolsAgentOutputParser() ) The purpose of the "OpenAIToolsAgentOutputParser()" component in the pipeline is to parse and process the output generated by the agent during interaction. Agent Executor The agent executor serves as the core engine for an agent, managing its operation by initiating activities, executing assigned tasks, and reporting outcomes. The following code demonstrates the instantiation of AgentExecutor. Python from langchain.agents import AgentExecutor agent_executor = AgentExecutor(agent=agent, tools=mytools, verbose=True, memory=memory, max_iterations=3) Session Management To manage sessions when executing the tool, we will use ChatMessageHistory, a wrapper that offers easy-to-use functions for storing and retrieving various types of messages, including HumanMessages, AIMessages, and other chat messages. The RunnableWithMessageHistory encapsulates another runnable and oversees its chat message history. It's responsible for both reading and updating the chat message history. Python from langchain_community.chat_message_histories import ChatMessageHistory from langchain_core.runnables.history import RunnableWithMessageHistory message_history = ChatMessageHistory() agent_with_chat_history = RunnableWithMessageHistory( agent_executor, lambda session_id: message_history, input_messages_key="input", history_messages_key="history", ) By default, the encapsulated runnable expects a single configuration parameter named "session_id," which should be a string. This parameter is utilized to either create a new chat message history or retrieve an existing one. Python agent_with_chat_history.invoke( {"input": message}, config={"configurable": {"session_id": conversation_id}, ) Conclusion Integrating AI chatbots driven by large language models offers businesses a significant chance to enhance internal operations, streamlining project management and customer support. However, security and hallucination concerns may hinder immediate adoption by external consumers. Careful consideration of these factors is essential before implementing AI chatbots for customer-facing purposes.

I knew a Chief Software Architect from a major financial organization who was an anomaly: he had never developed software professionally. His undergraduate degree is in Accounting and Finance, and his most hands-on technology role was as a DBA. [His LinkedIn profile lists an early Programmer role, though he insisted he didn’t.] Even so, he was well-respected within his organization for his thought leadership and solutions, but nevertheless, it seemed an unusual career path. Since I last worked with him, he has moved into C-level roles at other organizations, confirming his abilities as a technology leader. Then I thought of others I have worked with who are non-technical but positioned to impact technical direction and realized their lack of understanding impacted (and continues to impact) the quality of the software solutions we, as engineers, are expected to deliver. Chief Non-Technical Officer This CTO has been with her/his company for many years in many roles: Director of Support, Chief Strategy Officer, Chief Cultural Officer, and Chief Technical Officer. S/he does not deny that s/he is not a strong technologist – and at times a badge of honor – yet confidently states decisions and direction that they become a fait accompli: alternatives that challenge her/his understanding are not often well received. At times, her/his inner circle helps to form a more nuanced understanding, but only to a point: overcoming her/his existing preconceived notions is difficult, and blatant opposition results in being sidelined from future discussions. By no means is s/he a total technical novice, but fundamental change requires extensive effort and time. Her/his oft-repeated mantra went something like this: Don’t tell me you’re refactoring; refactoring brings no value to our customers. Harking back to her/his strategy days, where feature-feature-feature is the overwhelming driver, this mantra confirmed her/his denial or lack of understanding of the current state of the product. The growing and maturing customer base made clear that areas of the product needed love and attention, but proposed efforts to address them were not prioritized because – in her/his view of the world – there was no visible benefit to their customers, at least when focused on customers asking for new or extended features. The real technologists of the company understood the potential benefits to both the customer and company: performance and scaling improvements, reduced cloud costs, faster deployments, fewer outages, faster feature delivery, reduced technology stack, and consistent and intuitive user experience. Regardless of potential benefits, nothing called out as refactoring would survive planning. The problems continued to grow, and the problems continued to be ignored. Sigh. Product To be clear, I have no interest in becoming a product owner: the wide-ranging responsibilities require a breadth of knowledge and experience not often found in a single person, while their many stakeholders – both internal and external – have contradictory goals and agendas that need to be balanced. I view it as a political role, finding compromises that please (appease) most, with no one getting everything s/he desired. This role is not for the weak and timid. Once we accept that product owners are unlikely to have the background or experiences necessary to handle all responsibilities, we can then understand why the focus is on those responsibilities understood or deemed important by their leaders. Outside of organizations offering technical solutions, product owners often have a stronger business understanding than technology understanding based on their work experience. Perhaps not surprisingly, the product is defined by business expectations more so than technical requirements: future features and functionality are defined by understanding industry trends, reviewing customer feedback, interpreting — sales and usage analytics, defining the user experience, etc. In essence, the product owner is an overclocked business analyst. Real-World Example A particular product manager focused only on rapidly releasing new features regardless of technical stability. Over time, the issues rose to the point where outages – not processing failures, actual outages – occurred daily and could no longer be ignored. She continued to view the work as unnecessary and not beneficial to the product, resulting in this exchange during quarterly planning: The result is product owners often eschew – whenever possible – technology and technical viability aspects of the product, reducing the impact of technology during product planning. Instead of top-down planning, individual engineers attempt to push technical issues bottom-up, which is very difficult and often unsuccessful. Organizations require a strong engineering discipline and culture to offset the business focus of product owners, but it remains a frustrating challenge. [Of course, production technology issues do arise that demand immediate attention, but the resulting work is stressful, particularly for the engineers who are responsible for implementing the changes required; the result is often a one-off effort rather than fundamentally changing the overall culture.] The Not-Ready-For-Prime-Time Implementation This is less about an individual or role but rather an organizational culture problem: proof-of-concepts assumed to be production-ready. Software proofs-of-concept (POCs) are created to test new business concepts or determine the usefulness or applicability of new technology. POCs should be created with minimal engineering rigor that allows a quick and cheap implementation to be discarded without guilt once the results are evaluated. Most important, it is not intended to be a workable product. Despite these clear expectations, too often, I’ve seen the business get excited at seeing the POC and want it available to customers immediately. The POC might be slightly enhanced or it might be unaltered, but it’s out there for the world (internal or external) to use. And when the problems start appearing – because, by definition, it was not intended for real-world usage – the finger-pointing begins. Agile advocates snigger and say You needed an MVP, silly! but my experiences are much the same as POCs: poor. By definition, an MVP is a complete application without the bells and whistles, but corners are inevitably cut: crawling (of crawl/walk/run paradigm) when current volumes require walk, run, or even fly; minimal/non-existent observability; non-standard user experience; incomplete or incorrect API definitions; security through obscurity; incomplete error handling. When leaders decide to move forward after a successful MVP, the expectation is to expand and enhance the MVP implementation; in fact, it may be better to start over. [I am not disavowing MVPs’ usefulness but rather am clarifying that organizations misuse/abuse the term and are, in fact, creating glorified POCs that are not complete, are not ready for users, and are not production ready. Just saying…] So when you next hear of an access application that is integrated into the enterprise supply chain workflow, don’t say I didn’t warn you. Organizations who make ignorant decisions on the production-readiness of applications shouldn’t know why failures occur later, yet they do, and the engineers are left to pick up the pieces. What Can You Do? It’s not hopeless, really. It isn’t …. not necessarily fun, but there are strategies that you can attempt. Gather Create a personal archive of articles, use cases, scenarios, and data that allows you to tell stories to non-technical people, helping them understand the tradeoffs present in all organizations. Internally, you might be interested in estimated vs. actual effort for feature delivery, production failure rates, or implementation costs mapped to the customer base. Are cloud costs increasing faster than customer growth? Did assumptions made during initial implementation impact the ability to deploy future features, whether positive or negative? Is supposedly important work upended by unknown and unplanned initiatives? Did a potential security breach impact customer confidence? What was the cost of researching a potential security breach? Is data quality affecting your reporting, analytics, and billing? There are many different ways to try and understand what’s happening within your organization. Almost daily, there are new articles online that highlight the issues and problems other organizations experience: Southwest’s 2022 holiday meltdown, a ransomware attack on Vital Care Providers, and Cloudfare’s bad software deployment. Not every organization publishes postmortems, but details often leak through other channels. Perhaps more importantly, your organization doesn’t want to appear in those articles! Educate As most non-technical folks appear unable or unwilling to accept that software is hard, our responsibility – for better or worse – is to show and explain. Unique situations require adjusting the story told, but it is necessary – and never-ending – to have any chance to get the organization to understand: explaining how software is developed and deployed, demonstrating how a data-driven organization requires quality data to make correct decisions, explaining the advantages and disadvantages of leveraging open source solutions; showing examples of how open source licenses impact your organization’s intellectual property. Look for opportunities to inject background and substance when appropriate, as education is open-ended and never-ending. Often, it will appear no one is listening as you repeat yourself, but eventually – hopefully – someone will parrot what you’ve been saying for months. Negotiate Aside from those employed in purely research and development roles, engineering/technology for engineering/technology's sake is not feasible, as technology concerns must be balanced with business concerns: product and its competitors, sales pipeline, customer support and feature requests, security, privacy, compliance, etc. Each decision has its short- and long-term impacts, and it is very unlikely that all involved will be pleased. Sorry, but that’s corporate politics. That does not mean you roll over and play dead, but rather horse trade, often with management and product, to ensure the technical concerns aren’t forgotten: Ensure that changes in business priorities are coupled with impact analysis on in-process development efforts; Accept less-than-optimal initial implementations with the agreement of fast-follow work to address compromises; Define metrics that identify when technology-focused work should be prioritized over feature work. These ideas may or may not apply to your organization or situation, but hopefully, they will give you ideas that may be pursued. Conclusion The problems I’ve discussed are age-old and have seemed to become worse in recent decades, so I’m not sure if any of what I’ve discussed is a surprise. Perhaps this is only the latest incarnation of the problem and post-Agile a new approach will reap benefits. Perhaps leaders will acknowledge that engineers really do understand the problems and are trusted to implement a solution rather than given solutions that fit an arbitrary (and often unrealistic) timeline. It’s a tug-of-war that I don’t yet see resolved.

DevOps encompasses a set of practices and principles that blend development and operations to deliver high-quality software products efficiently and effectively by fostering a culture of open communication between software developers and IT professionals. Code reviews play a critical role in achieving success in a DevOps approach mainly because they enhance the quality of code, promote collaboration among team members, and encourage the sharing of knowledge within the team. However, integrating code reviews into your DevOps practices requires careful planning and consideration. This article presents a discussion on the strategies you should adopt for implementing code reviews successfully into your DevOps practice. What Is a Code Review? Code review is defined as a process used to evaluate the source code in an application with the purpose of identifying any bugs or flaws, within it. Typically, code reviews are conducted by developers in the team other than the person who wrote the code. To ensure the success of your code review process, you should define clear goals and standards, foster communication and collaboration, use a code review checklist, review small chunks of code at a time, embrace a positive code review culture, and embrace automation and include automated tools in your code review workflow. The next section talks about each of these in detail. Implementing Code Review Into a DevOps Practice The key principles of DevOps include collaboration, automation, CI/CD, Infrastructure as Code (IaC), adherence to Agile and Lean principles, and continuous monitoring. There are several strategies you can adopt to implement code review into your DevOps practice successfully: Define Clear Goals and Code Review Guidelines Before implementing code reviews, it's crucial to establish objectives and establish guidelines to ensure that the code review process is both efficient and effective. This helps maintain quality as far as coding standards are concerned and sets a benchmark for the reviewer's expectations. Identifying bugs, enforcing practices, maintaining and enforcing coding standards, and facilitating knowledge sharing among team members should be among these goals. Develop code review guidelines that encompass criteria for reviewing code including aspects like code style, performance optimization, security measures, readability enhancements, and maintainability considerations. Leverage Automated Code Review Tools Leverage automated code review tools that help in automated checks for code quality. To ensure proper code reviews, it's essential to choose the tools that align with your DevOps principles. There are options including basic pull request functionalities, in version control systems such as GitLab, GitHub, and Bitbucket. You can also make use of platforms like Crucible, Gerrit, and Phabricator which are specifically designed to help with conducting code reviews. When making your selection, consider factors like user-friendliness, integration capabilities with development tools support, code comments, discussion boards, and the ability to track the progress of the code review process. Related: Gitlab vs Jenkins, CI/CD tools compared. Define a Code Review Workflow Establish a clear workflow for your code reviews to streamline the process and avoid confusion. It would help if you defined when code reviews should occur, such as before merging changes, during feature development, or before deploying the software to the production environment. Specify the duration allowed for code review, outlining deadlines for reviewers to provide feedback. Ensure that the feedback loop is closed, that developers who wrote the code address the review comments, and that reviewers validate the changes made. Review Small and Digestible Units of Code A typical code review cycle should involve only a little code. Instead, it should split the code into smaller, manageable chunks for review. This would assist reviewers in directing their attention towards features or elements allowing them to offer constructive suggestions. It is also less likely to overlook critical issues when reviewing smaller chunks of code, resulting in a more thorough and detailed review. Establish Clear Roles and Responsibilities Typically, a code review team comprises the developers, reviewers, the lead reviewer or moderator, and the project manager or the team lead. A developer initiates the code review process by submitting a piece of code for review. A team of code reviewers reviews a piece of code. Upon successful review, the code reviewers may request improvements or clarifications in the code. The lead reviewer or moderator is responsible for ensuring that the code review process is thorough and efficient. The project manager or the team lead ensures that the code reviews are complete within the decided time frame and ensuring that the code is aligned with the broader aspects of the project goals. Embrace Positive Feedback Constructive criticism is an element, for the success of a code review process. Improving the code's quality would be easier if you encouraged constructive feedback. Developers responsible, for writing the code should actively seek feedback while reviewers should offer suggestions and ideas. It would be really appreciated if you could acknowledge the hard work, information exchange, and improvements that result from fruitful code reviews. Conduct Regular Training An effective code review process should incorporate a training program to facilitate learning opportunities for the team members. Conducting regular training sessions and setting a clear goal for code review are essential elements of the success of a code review process. Regular trainings play a role, in enhancing the knowledge and capabilities of the team members enabling them to boost their skills. By investing in training the team members can unlock their potential leading to overall success, for the entire team. Capture Metrics To assess the efficiency of your code review procedure and pinpoint areas that require enhancement it is crucial to monitor metrics. You should set a few tangible goals before starting your code review process and then capture metrics (CPU consumption, memory consumption, I/O bottlenecks, code coverage, etc.) accordingly. Your code review process will be more successful if you use the right tools to capture the desired metrics and measure their success. Conclusion Although the key intent of a code review process is identifying bugs or areas of improvement in the code, there is a lot more you can add to your kitty from a successful code review. An effective code review process ensures consistency in design and implementation, optimizes code for better performance and scalability, helps teams collaborate to share knowledge, and improves the overall code quality. That said, for the success of a code review process, it is imperative that the code reviews are accepted on a positive note and the code review comments help the team learn to enhance their knowledge and skills.
