  Initial iterations

  An early task for your new project it so configure an iteration path. Going a little further than the standard iteration model can help with planning later.

  Introduction

  The online documentation for iteration paths has a graphic which could cost you some time in the future. Care to guess?

  

  In case its not obvious, the sprint numbering starts from 1 again for each release. In my experience releases can move around but you really want sprints to be a consistent drum beat for the project.

  Sprints

  This first question you need to answer is how long will a sprint be? You shouldn’t be changing the length at all so picking a length can be tricky. The scrum guide says this:

  Sprints are the heartbeat of Scrum, where ideas are turned into value.

  They are fixed length events of one month or less to create consistency. A new Sprint starts immediately after the conclusion of the previous Sprint.

  A single week is less common but useful where you are not delivering software and have very short deadlines; though at this point maybe a simple kanban would be more efficient. The most common length is 2 weeks. Microsoft DevDiv adopted a 3 week duration. 4-weeks seems a little too long for me, long enough to be doing mini-waterfalls which is to be avoided.

  I once heard somewhere is the length of a sprint should be as long as you can go and risk going in the wrong direction. Since feedback from customers only comes at the end of each sprint the opportunity for course correction is similarly timed.

  Personally, if you are delivering software I would pick two weeks unless you can make a great case for three. This is especially true if you are new to agile - you really want that feedback regularly.

  I would also recommend that you don’t start/end sprints on Mondays or Fridays - these days are often when folks are not around for various reasons. Plus, who wants to spend all day in sprint meetings on a Friday.

  You can now go and create a bunch of sprints in Azure DevOps. Create a nice long, but flat, list of sprints at the project level with start and end dates.

  Releases and other Milestones

  Only after you have your sprint list should you apply any hierarchy to it. A sprint should deliver potentially shippable code but often not released. A release is a more formal affair. Scheduling with milestones can help with planning at epic or feature level for larger projects.

  For large, long running product deliveries your planning will reach further out than your PBI backlog. At range, things get fuzzy so trying to plan in detail is a futile waste of effort. Remember that any work items specified but not delivered are considered inventory and incomplete work depreciates rapidly with knowledge and feedback gained along the way.

  To help, I’m a fan of multiple levels as shown below (also from Microsoft). At the top you have a strategic outlook for the next 12 months. These consist of epics only. Below that a roadmap of features you plan to deliver over the next six months. PBIs don’t start to appear until the quarterly plan which is your main backlog. Finally tasks are created during sprint planning.

  

  However you break this up you will have a hierarchy of iterations similar to the following:

  • Vision-2024
    • Roadmap-2024-H1
      • Plan-2024-Q2
        • Sprint-1
        • Sprint-2
        • Sprint-3
        • Sprint-4
        • Sprint-5
        • Sprint-6
    • Roadmap-2024-H2
      • Plan-2024-Q3
        • Sprint-7
        • Sprint-8
        • Sprint-9
        • Sprint-10
        • Sprint-11
        • Sprint-12
      • Plan-2024-Q4
        • Sprint-13
        • Sprint-14
        • Sprint-15
        • Sprint-16
        • Sprint-17
        • Sprint-18
  • Vision-2025
    • Roadmap-2025-H1
      • Plan-2025-Q1
        • Sprint-19
        • Sprint-20
        • Sprint-21
        • Sprint-22
        • Sprint-23
        • Sprint-24
      • Plan-2025-Q2
    • Roadmap-2025-H2
  • Vision-2026

  With a structure like this you can throw epics and features into a future planning bucket without worrying which iteration. This is a bit generic though; far better if you have catchy names for the vision, roadmap and plan levels since its easier to remember which one is current.

  Sprints won’t neatly fit into calendar boundaries like quarters, halves and years but its not a big deal. Just put an extra sprint somewhere or one less to keep them from drifting. Make sure the numbering is sequential still. Teams just work with sprints and its confusing if the sequence jumps.

  Also, there are no releases on this list, just planning windows. Releases are orthogonal to iterations and move around a lot so the release a work item is completed in may not be the one originally intended. You can use build and release numbers for tracking this instead.

  Since teams can use different iterations then unfortunately you need to select iterations at a team level too which just needs a lot of clicking. Go click one more time on Team Configuration Option: Auto Populate Team Iterations with Project Iterations if you would rather have them auto populated instead.

  If you are going to be doing a lot of this then scripting the creation of iterations is a way to save some time.

  Summary

  Usually iterations don’t get much thought at the start of a project and end up being rearranged as you need but they can be a useful way of planning deliveries at just the right level.

  Picking the Perfect Process (model)

  Which process model should you pick for your brand new Azure DevOps project? You can change later but its easier to get it right at the start. Some processes might even cause you issues.

  Introduction

  There are four process models supplied currently: Basic, Agile, Scrum, and CMMI. I’m not going to regurgitate the information already available online. Go and read for yourself the main distinctions among the default processes. Some differences might not be that obvious but will become apparent later.

  History

  Azure DevOps has technically been around for quite some time. Before its current incarnation it used to be an on-premise version called Team Foundation Server (TFS). Before that I belive it existed as a Microsoft internal tool called Source Depot, but that might just have been the source control tool. TFS had two process templates - Agile and CMMI. Both of these were designed specifically for the Microsoft Solutions Framework process used by Microsoft Consulting Services, and others. It was part of my job at Microsoft to go and talk to customers about it as you can see from this very dated PowerPoint. Gotta love that gold gradient shadow text.

  

  The two flavours of this process were MSF for Agile Software Development and MSF For CMMI® Process Improvement.

  

  So, the current Agile and CMMI process models have been around for a while. Both of them pre-date the first official Scrum guide release in 2010. They have been tweaked but not really modified to stay current. I can’t imagine any team in Microsoft follows these processes any more.

  Making Your Selection

  The history above is useful context but doesn’t say why you shouldn’t use these models apart from the fact they are old.

  The CMMI process is really heavy with extra work item types and states used to manage a formal change management process. Work items have lots more fields that need to be filled out and steps from start to finish. It doesn’t scream agile.

  The Agile process, on the other hand, is a bit sly. It uses the right terms like User Story, Acceptance Criteria, and Story Points but a couple of things don’t really marry with modern agile.

  Firstly, the state transitions New > Active > Resolved > Closed. There isn’t a state that really represents the backlog. You could use New but then you are mixing up work with the half baked ideas that may not make it onto the backlog. Also, the Resolved state implies there must be some form of verification before closure and that they must be done in order. Cross functional agile teams work together on committed work items until they are done. Sequencing work via a Resolved step means you are queuing.

  Some fields can be unhelpful too specifically the Completed Work field which I wrote about a long time ago: https://snape.me/2014/09/06/tracking-hours-worked-on-a-scrum-task-is-counterproductive/. Interestingly, I’ve just checked my current Azure DevOps and this field has been removed from the Agile process so it is being improved.

  To recap the above in a nice easy summary.

  Do not use the Agile or CMMI process models.

  The two remaining models are Basic and Scrum. I love them both but they have very different purposes.

  The Basic process model it reduced to a bare minimum. All work items are simply Issues with a higher level Epic. To differentiate different types of work you use tagging in the same way GitHub uses labels on its issues. Issue states are To Do > Doing > Done without extra process steps too.

  The Scrum process model really looks like modern scrum with Approved > Committed > Done states to map onto product backlog, sprint backlog and done respectively. Additional approval states are removed to encourage in-sprint completion. Even the terminology of Done vs Closed maps better onto agile. Feature work items aren’t defined in scrum but I find them useful as a unit of release deliverable vs product backlog item (PBI) as a unit of sprint deliverable (more on this in a future post).

  My rule of thumb for choosing between these two process models is:

  It the process is for delivering software then pick Scrum otherwise pick Basic.

  I use the Basic process model all the time for ad-hoc boards and task tracking for example: tracking architecture review board work, personal to do lists, support ticketing, governance structures etc. It is particularly useful for use with business users and other non-technical customers because most folks will understand the basics of a to do list whereas trying to describe the nuances between a task, a bug and a product backlog item can be tricky.

  Dealing With Process Jealousy

  OK, so you picked Basic or Scrum but you quite like some of the things in other process models? That isn’t too much of an issue since you can copy the definition of an interesting work item from the model it lives in to your model. There is an important point though:

  Always create an inherited process before selecting one for your projects.

  You cannot change the standard processes so save yourself a minor inconvenience in the future by creating a model you can modify when you need to.

  Examples of work item types I often add are:

  • Question - used to document known unknowns typically associated with architecture or planning activities.
  • Decision - for tracking decisions that need making and the outcome of those decisions.
  • Feedback - used to formally track feedback from show and tell sessions. Often I prefer to just add new children (tasks or PBIs) to the existing work item than needs more effort.

  Finally

  Its a trivial step at the point you create a project in Azure DevOps. Picking the right process model can help point you in the right direction. I’m interested in how you chose the right process or what work item types would you add? Click one of the buttons below and tell me.
