Using the pre-defined Scrum process

I've recently been asked for more guidance about using the pre-defined Scrum process in version 2.9 of xProcess. It uses some of the new features for process definition (like Composite tasks) and also has "top-down" estimating for projects built-in, which is useful for resource planning and financial reporting. So I'm planning to post a series of blog entries on the process and in this one I'll focus on getting started with this process "out of the box". Here's what it covers:
  • Creating a Scrum project
  • Adding resources to the project
  • Adding Sprints to the project (a Sprint in Scrum is like a "timebox" in other methods)
  • Adding Backlog Items to the project (Backlog Items are the tasks the project must achieve)
So step one is to select the Project Manager perspective (the default) and hit the "New" button so we can make a Scrum project. The New project dialog shows the processes that are available for import, so if you've not already done so this is the point to import "Basic Scrum 2.9.0" and then select "Scrum Project" as your type of project. You can fill in the name and other details of the project (such as the number of 4-week Sprints and a location of a Wiki if you are using one) on this dialog.

At this point take a look at the set of tasks that are already in the project (hitting the "Tasks" button is the quickest way to do this. Here's what you might see (click on the image to make it full size).

There are:
  • some overhead tasks (green because they have fixed start and end dates and are within the target dates of the project)
  • A "Sprints" parent task containing one sprint "Sprint 01" (these tasks are red since they have NEVER end dates, clearly after the project target)
  • An "Unscheduled Backlog" (which is grey as this task is specified as not to be scheduled, also resulting in NEVER end dates).
In the pane below the project details, you can also see there are some alerts displayed telling us that this project needs resources with particular role types. That's a clue to our next step - add resources. Hit the "Resources" button on the "Tools" pane and you'll see an "Add/New Project Resource" button. If you've already defined or imported a set of people you can select those who are going to be on the project, or you can create new persons at this point. Add six team members (Participant role) and one team leader (Scrum Master role) to the project.

At this point we should see actual end dates appearing for the Sprints and the overall project and we can even see a Gantt chart and projected Burndown chart. The Burndown chart is slightly more interesting if we add 2 more Sprints to the project (hit the "New" button and select "Sprint"). Then hit the "Burndown Chart" button on the project pane and you should see something like this:

Now it's important to note that as yet we've entered very little information about this project other than the number of Sprints and the people on the project and their availability. The projected burndown is only reflecting this simple data showing when the work in each Sprint (based on estimates for the amount of work in a Sprint which is modifiable in the process definition or, for a specific Sprint by modifying the estimates in its "Required Resources"). To use Scrum in earnest we need some actual "Backlog Items". Backlog Items are identifiable tasks that in a software development project for example could correspond to features to be built or defects to be corrected. The next step therefore is to add such items.

Hit the "New" button again and select "Backlog Item" (and then "Next"). We have a choice of the 3 Sprints we've defined or the "Unscheduled Backlog" as valid parent tasks for these items. Setting the parent task as Unscheduled Backlog means that we can create a set of tasks without them changing the scheduling of the project. We can then decide later in which Sprint specific tasks should be completed. So with Unscheduled Backlog as the parent task you can give the backlog iten a name and a size (size is measured in "ideal days" by the way), and hit "Finish" and the task will created. If you already have a list of tasks you can copy and paste a comma-separated list into the name field of the "New" dialog, check the "Create Multiple" check-box and several items will be created in one go.

Now we have a project some resources and set of tasks to be completed. The next step is prioritising. We'll look at that in the next posting in this series.

Does your Definition of Done allow known defects?

Is it just me or do you also find it odd that some teams have clauses like this in their definition of done (DoD)?
... the Story will contain defects of level 3 severity or less only ... Of course they don't mean you have to put minor bugs in your code - that really would be mad - but it does mean you can sign the Story off as "Done"if the bugs you discover in it are only minor (like spelling mistakes, graphical misalignment, faults with easy workarounds, etc.). I saw DoDs like this some time ago and was seriously puzzled by the madness of it. I was reminded of it again at a meet-up discussion recently - it's clearly a practice that's not uncommon.

Let's look at the consequences of this policy. 

Potentially for every User Story that is signed off as "Done" there could be several additional Defect Stories (of low priority) that will be created. It's possible that finishing a Story (with no additional user requirements) will result in an increase in…

"Plan of Intent" and "Plan of Record"

Ron Lichty is well known in the Software Engineering community on the West Coast as a practitioner, as a seasoned project manager of many successful ventures and in a number of SIGs and conferences in which he is active. In spite of knowing Ron by correspondence over a long period of time it was only at JavaOne this year that we finally got together and I'm very glad we did.

Ron wrote to me after our meeting:

I told a number of people later at JavaOne, and even later that evening at the Software Engineering Management SIG, about xProcess. It really looks good. A question came up: It's a common technique in large organizations to keep a "Plan of Intent" and a "Plan of Record" - to have two project plans, one for the business partners and boss, one you actually execute to. Any support for that in xProcess?

Good question! Here's my reply...

There is support in xProcess for an arbitrary number of target levels through what we call (in the process definitions) P…

Understanding Cost of Delay and its Use in Kanban

Cost of Delay (CoD) is a vital concept to understand in product development. It should be a guide to the ordering of work items, even if - as is often the case - estimating it quantitatively may be difficult or even impossible. Analysing Cost of Delay (even if done qualitatively) is important because it focuses on the business value of work items and how that value changes over time. An understanding of Cost of Delay is essential if you want to maximise the flow of value to your customers.

Don Reinertsen in his book Flow [1] has shown that, if you want to deliver the maximum business value with a given size team, you give the highest priority, not to the most valuable work items in your "pool of ideas," not even to the most urgent items (those whose business value decays at the fastest rate), nor to your smallest items. Rather you should prioritise those items with the highest value of urgency (or CoD) divided by the time taken to implement them. Reinertsen called this appro…
