Latest patterns for Scrum

xProcess 2.8 is being released this week and among the exciting new capabilities are some new sample processes, including updates to the Scrum patterns. Here are some of the highlights.

Firstly the project pattern for the "Basic Scrum" process is now built from composite tasks so that there is a standard structure that is provided for all its projects. The Hierarchy diagram shows the structure, having top-level tasks for: General and Scrum administration overheads (overheads are unplanned or unplannable tasks that take up a proportion of everyone's time); the Sprints (a composite task which contains an iteration of Sprint instances); and the Unscheduled Backlog (a composite which contains a collection of Backlog Items).

You can also see from this diagram the structure of the Sprint and Backlog Item patterns. Sprint is a collection of the Backlog Items to be scheduled over the period, and consists of a single task. The beuty of xProcess of course is that these patterns can be modified to match the way your team is working or the particular application of Scrum that you are using. For example if you are using Scrum with XP you might want to rename the Backlog Item pattern to User Story and perhaps provide some structure to the set of tasks and role types that corresponds to0 the way you are using the method.

When you make a new Scrum Project in xProcess you'll be prompted for values of the parameters of the pattern. You can see these in this screenshot, where as well as defining the name of the project the start date, duration (the number of 4 week Sprints) and the Wiki location.
The Wiki location is not a required field but we've found many people find wikis are a convenient way to group documentation. By providing the location of the wiki in this dialog the descriptions of your backlog items are automatically transferred to a wiki page while also being browsable and editable in xProcess views.

Having created your Scrum project from this pattern, the next thing to do is add your resources. You need to add someone with a Scrum Master role and the others with Participant roles - let's say six participants in this example.

Because the tasks in the Scrum pattern are defined as top-down, even at this stage xProcess is able to provide a project schedule, based on the specified duration of the project. More usefully though, this is the time to create the first Sprint (right-click on the Sprints task and select New...) and then create some Backlog Items, either in the Sprint or in the Unscheduled Backlog if we don't yet know which Sprint we want them to be completed in. Backlog Items are prioritized, firstly from the particular Sprint into which they are created or moved, and secondly by the priority order of the tasks within a Sprint. You can edit this priority order by opening the Sprint editor, clicking on the priorities tab and either dragging and dropping or changing the priority number.

Once you have a Sprint which contains the items the team will be implementing, open the Burndown view. This provides both the history of how much work has been completed so far in the Sprint and a forecast of what should be completed. You'll see immediately for example if there's too much work in there and forecast dates are beyond the end of the Sprint. Here's an example of just one such Sprint...

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…
