Poor Oddjob, I thought as I read Craig Flichel’s Feature Comparison of Java Job Schedulers featuring Obsidian, Quartz, Cron4j and Spring. Yet again it hasn’t made the grade, it’s been passed over for the scheduling team. Never mind I say, you’re just a little bit different and misunderstood. Let’s have a kick about in the back yard and see what you can do… Real-time Schedule Changes / Real-time Job Configuration Oddjob: Yes Here is Oddjob’s Client GUI, connecting to an instance of Oddjob running as a Windows Service on my home PC. My Oddob instance sends me a reminder email when it’s someone’s birthday, and also tells me when it’s going to rain. The swing UI allows complete configuration of the server. With it I can configure the jobs and their schedules, but unfortunately I can’t control the weather! Ad-hoc Job Submission: Yes Configurable Job Conflicts: Not Really Applicable Ad-hoc job submission is really what Oddjob is all about. Many jobs won’t be scheduled at all and will sit in a folder to be manually run as required. To run a job, scheduled or not, just click ‘run’ from the job menu. Job conflicts aren’t really a problem for Oddjob because it won’t reschedule a job again until it’s finished. If a job’s next slot has passed, you have the choice to run immediately or skip missed runs and reschedule from the current time. If you want concurrent execution you can configure different jobs to run at the same time or use a single schedule and launch the jobs in parallel. Manually Stopping a job is just as easy as running it. Click ‘stop’ from the job menu. Code- and XML-Free Job Configuration Oddjob: Yes You saw this in the first section. Oddjob’s configuration is via a UI and is done in real time. In fact I often start one job as I’m configuring the next. It’s all very interactive. Oddjob uses XML behind the scenes for those that like to see under the hood. Job Event Subscription/Notification Oddjob: Yes It’s very easy to trigger a job based on the completion state of another job. You would have to write code to listen to configuration changes though. Custom Listeners: Undocumented Job Chaining: Yes There’s lots of options for job chaining, sequential, parallel, or cascade, and any nested combinations thereof. Adding a custom Stateful listener would be easy enough, and might be useful if embedding Oddjob but this isn’t the normal use case. The unit tests do this extensively however. Monitoring & Management UI Oddjob: Yes The same UI allows you to see the job state, job by job log messages, the console of an Exec Job, and the run time properties of all the jobs. Zero Configuration Clustering and Load Sharing Oddjob: Kind Of Oddjob has a Grab Job so you can run the same configuration on several servers and have them compete for work. I wrote it as a proof of concept but I’ve never had cause to use it in the field and I haven’t had any reports that others have either. Job Execution Host Affinity: Kind Of In the same way that you add the ‘Grab job’ to many servers to share work, you could in theory just add Grab for a particular job to only certain servers. I guess this is server Affinity? Scripting Language Support in Jobs Oddjob: Yes Oddjob has a Script Job for any language that supports the Java Scripting Framework. JavaScript is shipped by default.With the Script Job you can also interact with Oddjob to use the properties of other jobs, and set variables for other jobs to use. Scheduling Precision Oddjob: Millisecond In theory Oddjob can schedule with millisecond precision, but this isn’t usual practice. Polling for a file every 30 seconds, for instance, is normally fine. Job Scheduling & Management REST API Oddjob: JMX Only No REST API. You can embed the JMX Client easily enough and control everything from Java, but not for other languages. Not yet. Custom Calendar Support Oddjob: Yes Oddjob has the concept of breaking a schedule with another. The breaks can be as flexible as the job schedule itself – define days, weeks or just a few hours off for a task. The Scheduling section of the User Guide has much more on Oddjob’s flexible scheduling capabilities. Conclusion Oddjob has many other features to make automating repetitive tasks easy. One noteworthy feature is the ease of adding custom jobs by just implementing java.lang.Runnable. Oddjob is undeniably an amateur player in the Scheduler league, and one that is often overlooked. With its Apache licence it is completely free and open. Why not check it out when you have an hour or two? You might be pleasantly surprised by the quality of play.

Micromanagement is sometimes counterproductive when it comes to deadline-oriented work. Here's what experts recommend doing instead for increased efficiency.

Agile - What’s a Manager to Do? As a manager, when I first started learning about Agile development, I was confused by the fuzzy way that Agile teams and projects are managed (or manage themselves), and frustrated and disappointed by the negative attitude towards managers and management in general. Attempts to reconcile project management and Agile haven't answered these concerns. The PMI-ACP does a good job of making sure that you understand Agile principles and methods (mostly Scrum and XP with some Kanban and Lean), but is surprisingly vague about what an Agile project manager is or does. Even a book like the Software Project Manager’s Bridge to Agility, intended to help bridge PMI's project management practices and Agile, fails to come up with a meaningful job for managers or project managers in an Agile world. In Scrum (which is what most people mean when they say Agile today), there is no place for project managers at all: responsibilities for management are spread across the Product Owner, the Scrum Master and the development team. We have found that the role of the project manager is counterproductive in complex, creative work. The project manager’s thinking, as represented by the project plan, constrains the creativity and intelligence of everyone else on the project to that of the plan, rather than engaging everyone’s intelligence to best solve the problems. In Scrum, we have removed the project manager. The Product Owner, or customer, provides just-in-time planning by telling the development team what is needed, as often as every month. The development team manages itself, turning as much of what the product owner wants into usable product as possible. The result is high productivity, creativity, and engaged customers. We have replaced the project manager with the Scrum Master, who manages the process and helps the project and organization transition to agile practices. Ken Schwaber, Agility and PMI, 2011 Project Managers have the choice of becoming a Scrum Master (if they can accept a servant leader role and learn to be an effective Agile coach – and if the team will accept them) or a Product Owner (if they have deep enough domain knowledge and other skills), or find another job somewhere else. Project Manager as Product Owner The Product Owner is command-and-control position responsible for the “what” part of a development project. It's a big job. The Product Owner owns the definition of what needs to be built, decides what gets done and in what order, approves changes to scope and makes scope / schedule / cost trade-offs, and decides when work is done. The Product Owner manages and represents the business stakeholders, and makes sure that business needs are met. The Product Owner replaces the project manager as the person most responsible for the success of the project (“the one throat to choke”). But they don’t control the team’s work, the technical details of who does the work or how. That’s decided by the team. Some project managers may have the domain knowledge and business experience, the analytical skills and the connections in the customer organization to meet the requirements of this role. But it’s also likely to be played by an absentee business manager or sponsor, backed up by a customer proxy, a business analyst or someone else on the team without real responsibility or authority in the organization, creating potentially serious project risks and management problems. Some organizations have tried to solve this by sharing the role across two people: a project manager and a business analyst, working together to handle all of the Product Owner’s responsibilities. Project Manager as Scrum Master It seems like the most natural path for a project manager is to become the team’s Scrum Master, although there is a lot of disagreement over whether a project manager can be effective – and accepted – as a Scrum Master, whether they will accept the changes in responsibilities and authority, and be willing to change how they work with the team and the rest of the organization. The Scrum Master is a “process owner” and coach, not a project manager. They help the team – and the Product Owner – understand how to work in an Agile process framework, what their roles and responsibilities are, set up and guide the meetings and reviews, and coach team members through change and conflict. The Scrum Master works a servant leader, a (nice) process cop, a secretary and a gofer. Somebody who supports the team and the Product Owner, “carries food and water” for them, tries to protect them from the world outside of the project and helps them solve problems. But the Scrum Master has no direct authority over the project or the team and does not make decisions for them, because Agile teams are supposed to be self-directing, self-organizing and self-managing. Of course that’s not how things start off. Any group of people must work their way through Tuckman’s 4 stages of team development: Forming-Storming-Norming-Performing. It’s only when they reach the last stage that a group can effectively manage themselves. In the mean time, somebody (the Scrum Master / Coach) has to help the team make decisions that they aren’t ready to make on their own. It can take a long time for a team to reach this point, for people to learn to trust each other – and the organization – enough. And it may not last long, before something outside of the team’s control sets them back: a key person leaving or joining the team, a change in leadership, a shock to the project like a major change in direction or cuts to the budget. Then they need to be led back to a high performing state again. Coaching the team and helping them out can be a full-time job in the beginning. After the team has got together and learned the process? Not so much. Which is why the Scrum Master is sometimes played part-time by a developer or sometimes even rotated between people on the development team. But even when the team is performing at a high level, there’s more to managing an Agile project than setting up meetings, buying pizza and trying to stay out of the way. I've come to understand that Agile doesn't make a manager’s job go away. If anything, it expands it. Managing Upfront First, there’s all of the work that has to be done upfront at the start of a project – before Iteration Zero. Identifying stakeholders. Securing the charter. Negotiating the project budget and contract terms. Understanding and navigating the organization’s bureaucracy. Figuring out governance and compliance requirements and constraints, what the PMO needs. Working with HR, line managers and functional managers to put the team together, finding and hiring good people, getting space for them to work in and the tools that they need to work with. Lining up partners and suppliers and contractors. Contracting and licensing and other legal stuff. >/p> The Product Owner might do some of this work - but they can't do it all. Managing Up and Out Then there’s the work that needs to be managed outside of the team. Agile development is insular, insulated and inward-looking. The team is protected from the world outside so they can focus on building features together. But the world outside is too important to ignore. Every development project involves more than designing and building software – often much more than the work of development itself. Every project, even a small project, has dependencies and hand-offs that need to be coordinated with other teams in other places, with other projects, with specialists outside of the team, with customers and partners and suppliers. There is forward planning that needs to be done, setting and tracking drop-dead dates, defining and maintaining interfaces and integration points and landing zones. Agile teams move and respond to change quickly. These changes can have impacts outside of the team, on the customer, other teams and other projects, other parts of the organization, suppliers and partners. You can try using a Scrum of Scrums to coordinate with other Agile teams up to a point, but somebody still has to keep track of dependencies and changes and delays and orchestrate the hand-offs. Depending on the contracting model and your compliance or governance environment, formal change control may not go away either, at least not for material changes. Even if the Product Owner and the team are happy, somebody still has to take care of the paperwork to stay onside of regulatory traceability requirements and to stay within contract terms. There are a lot of people who need to know what’s going on in a project outside of the development team – especially in big projects in big organizations. Communicating outwards, to people outside of the team and outside of the company. Communicating upwards to management and sponsors, keeping them informed and keeping them onside. Task boards and burn downs and big visible charts on the wall might work fine for the team, but upper management and the PMO and other stakeholders need a lot more, they need to understand development status in the overall context of the project or program or business change initiative. And there’s cost management and procurement. Forecasting and tracking and managing costs, especially costs outside of development labor costs. Contracts and licensing need to be taken care of. Stuff needs to be bought. Bills need to be paid. Managing Risks Scrum done right (with XP engineering practices carefully sewed in) can be effective in containing many common software development risks: scope, schedule, requirements specification, technical risks. But there are other risks that still need to be managed, risks that come from outside of the team: program risks, political risks, partner risks and other logistical risks, integration risks, data quality risks, operational risks, security risks, financial risks, legal risks, strategic risks. Scrum purposefully has many gaps, holes, and bare spots where you are required to use best practices – such as risk management. Ken Schwaber While the team and the Product Owner and Scrum Master are focused on prioritizing and delivering features and resolving technical issues, somebody has to look further out for risks, bring them up to the team, and manage the risks that aren't under the team’s control. Managing the End Game And just like at the start of a project, when the project nears the end game, somebody needs to take care of final approvals and contractual acceptance, coordinate integration with other systems and with customers and partners, data setup and cleansing and conversion, documentation and training. Setting up the operations infrastructure, the facilities and hardware and connectivity, the people and processes and tools needed to run the system. Setting up a support capability. Packaging and deployment, roll out planning and roll back planning, the hand-off to the customer or to ops, community building and marketing and whatever else is required for a successful launch. Never mind helping make whatever changes are required to business workflows and business processes that may be required with the new system. Project Management doesn't go away in Agile There are lots of management problems that need to be taken care of in any project. Agile spreads some management responsibilities around and down to the team, but doesn’t make management problems go away. Projects can’t scale, teams can’t succeed, unless somebody – a project manager or the PMO or someone else with the authority and skills required – takes care of them.
