Becoming agile practitioners wasn’t a cakewalk for us. We crossed many hurdles to reach where we are — a place where we are not just incorporating an agile approach in our projects but all in all our in-house processes. Tools like JIRA, Basecamp, Slack, and many more have become our go-to stop for all our collaboration and communication. Today, we have become experts at Agile but it didn’t come so easy to us. 

The initial path was rough and we were faced with many misconceptions and myths. Over the years, we learned more about the process and along with it, we also embraced DevOps and Scrum. Today, when we see people still fearing Agile or failing at it or even more — mistaking Agile for Scrum and DevOps, we feel like we have to debunk all the myths. 

We all know that Agile, DevOps, and Scrum are some of the most popular processes that are used by developers all over the world in creating various products and apps. But what needs to be changed are the misconceptions surrounding them. Through this write-up, we seek to clear all the myths surrounding Agile, DevOps, and Scrum.

Difference Between DevOps and Agile

DevOps is a method where the focus lies on integration, communication, and collaboration to enable rapid deployment of the process. 

Agile Method, on the other hand, involves continuous development and testing in its SDLC process to break the product down into smaller portions which are then integrated for the final testing. 

Scrum is one of the many methods of implementing Agile. The agile method can also be used as part of the operation of DevOps.

While these are all unique in their ways, with their pros and cons, there are always debates over the use of each. To know which is better for your particular needs, it is important to understand what these are and how they are different from each other.

  • While DevOps is seen as a practice that works by getting the development and operations teams to work together to deliver the finished product, Agile works by delivering smaller quick releases, collaboration and working on customer feedback. Thus, while DevOps does the work quicker, Agile takes longer but deals with any feedback instantly.
  • DevOps focuses management of end-to-end engineering processes, by ensuring constant testing and final delivery. Agile is aimed at the management of complex projects concerning the constant changes and upgrades as needed. It is a reiterative model as opposed to DevOps which works with the entire process at a go.
  • With its focus on collaboration and development, DevOps is perfect for a large team at work making it a more efficient process for a larger development need. On the other hand, Agile development works best with smaller teams but it can deal with constant customer feedback, and work on developments and changes while it is being processed, making it easier for customers who are on the pickier side or need more changes.

There are several myths popularly ascribed to DevOps, Agile and Scrum which makes it daunting especially for new developers who are just getting hold of the software development scenario. It is important to focus on debunking these myths and seeing reality, to get a clearer outlook on every method, and to understand which works best for you.

Myths About Agile Development

Agile Means Slow and Chaos

Agile means sprints and sprints mean no deadlines! Well, this is not true!

The working principle of Agile is to break down the development into smaller processes and work on them, considering the customer feedback and integrating these reviews into the final product. 

There are levels of the organization working in Agile, making it more customer-friendly. Software development without agile means the customers only see their final products and it might need many changes. With sprint-based development and continuous iterations, the product that you get in the end would be flawless. 

While it takes a little longer time, it also makes the final product delivery without any hitches.

Agile Needs No Documentation Or Planning

There is another myth around Agile and that is you do not need to document or plan when being an Agile Practitioner. Many of our clients have come to us and asked if we are documenting everything and our answer has been simple — Yes!

After each iteration or the defining of the user needs, you must document every need to meet the expectations of the stakeholders. As an advancement over the older traditional development, Agile does away with a lot of excess documentation but every essential process requires documentation. This is how you make it efficient and handle it easily. 

There is also a great deal of planning required regarding the sprints and the iterations. But with each small process being handled, the plan moves on to the next process.

Agile Makes You Work On Same Stuff Again and Again

There is a fair bit of rework involved as every process is completed with adequate customer feedback, but once it is set, there is no rework to be done later as the final product is integrated. 

Agile is thorough but there is no scope of redundancy or additional rework than that is necessary. In the case of customers who change their minds, it is the easiest method to reach an agreement on.

Myths About DevOps

DevOps Is a Technology To Be Purchased

One of the biggest misconceptions that people have for DevOps is that it is a kind of technology or a set of tools that they can purchase. We have had many inquiries where our clients asked if we offered DevOps in our technology stack. This myth needs to be busted. 

DevOps is not some technology, tools, or skills. It is a strategy, an approach, a methodology that you incorporate in your business processes, especially in software delivery. It brings about a shift in the workflow and culture in a particular organization. 

It is a way of working through continuous and constant deploying, monitoring, collaboration, integration, delivery, and testing. It is only when these processes are mastered, that you can make the best use of your DevOps tools.

DevOps = NoOps

No, DevOps is not done when you train your developers to take care of the IT functions and make the IT operations team obsolete from the workspace. DevOps aims for a methodology, a continuous movement, that organizations embrace to automate the process and increase the team’s resilience.

This does not mean that the developers would be independent of the operations. This simply seeks to empower both the teams to deal with any minor obstacle on their own without being dependent on others.

They cannot be wizards with a magical wand; one swipe and all their tasks would be completed. 

While DevOps engineers can work on infrastructure maintenance and its improvement, they still rely on other teams & departments, especially the operations and IT for their complete operations. 

DevOps Replaces Agile 

It is important to understand that both DevOps and Agile methods work on different principles and hence, are best suited for different kinds of development projects. This is enough to say that it is almost impossible for DevOps to replace the Agile or vice versa. In the ethos of software development, both are essential and serve their unique purposes.

Myths About Scrum

Scrum Is Super Cheap

If you are approaching Scrum with the sole motivation of it being cheap, you are in for a rude shock. While it might come out to be more cost-efficient, it is not a process where you can compromise on the costs and get good results.

Scrum Wastes Time In Meetings

Scrum is a process that acknowledges the qualities and contributions made by each individual in the team while promoting self-organization. However, there are many followers of Scrum or rather abandoners of Scrum who feel that it makes them waste a lot of their time attending meetings.

This myth needs to be debunked.

Scrum works on Scrum Events that comprise Sprints. This means- the teams or individuals get a specific period within which they are supposed to complete the task at hand. There are Sprint Planning, Daily Scrums, product or MVP development, Review, and Sprint Retrospective that make part of a single sprint. A specific goal is set and there is no meeting in between the sprints. 

If you already had the culture of having regular meetings, Scrum might seem like an extra for the meetings but if you adopt the approach as it genuinely is, it would certainly reduce the time invested in meetings. 

Scrum Master Must Resolve Every Problem

There is another common myth around the organizations and even clients following Scrum that if you have a Scrum Master, all your issues will be automatically resolved by him/her. While this is believed by many, it is only true to a certain limit.  

The Scrum Master is not standalone when it comes to solving any problem. No one, in any process, team, organization, or industry can handle and resolve all the issues on his/her own. The main job of the Scrum Master is to aid the Development Team so that it can resolve the problem and also enable them to resolve any further problems on similar issues without any help.

Key Takeaways

  • DevOps, Agile, and Scrum methodologies are three of the most effective ways to get outsourcing contracts completed in time.
  • Many people confuse DevOps, Agile, and Scrum and use them interchangeably. But there is a stark difference between each process and one needs to have a good understanding of it. 
  • Depending on the project requirements, size, and complexity, one can choose from DevOps, Agile, Scrum.  
  • There are several myths associated with DevOps, Agile, Scrum. Not debunking them would help you make a well-informed decision

It is important to debunk the myths associated with these processes to not pit one against another. In most large-scale developments, often all these processes are employed together depending on the need for the work, to offer the most efficient solution for all needs. The best software development solutions come from a harmonious use of development methods.
