The types of things you might want to consider once you're up and running with the basic process include:
- Adding different role types if there are areas of specialisation within the team
- Adding artifact templates for essential documents
- Adding gateways to tasks (quality checklists)
- Adding structure to the "Backlog Item" pattern, for example subtasks of a standard form
- Adding different types of Backlog Item with different roles, estimates, gateways, structure and so on.
This diagram shows the hierarchy in the Scrum Project pattern. It consists of a project, named in the pattern as "$Name$" (this string will be substituted with the name the user supplies for the project). It has a General Overheads... task and a Scrum administration... task, both of which cover background work not related to backlog items. The Backlog Item pattern appears 3 times within the project pattern: in the first sprint, Sprint 01; within the Sprint pattern (which can be instantiated within the Sprints parent task as many times as required for Sprint 02, Sprint 03, etc.); and within the Unscheduled Backlog task. In order to add additional or alternative patterns, all 3 of these locations will need to be modified slightly so that the new patterns appear in place of, or additional to, the Backlog Item pattern.
Here's the situation after adding 2 new patterns for Defect and Enhancement as alternatives to the general Backlog Item. This will give the Project Manager a choice of the types of backlog item she wants to make in each case.
One word of confession here: to add extra pattern shortcuts like this means that the composite task that contains them (Sprint 01 for example) must be a selection composite rather than a collection composite. In version Basic Scrum 2.9.0 they are collections so you either need to change this or, to save hassle, use version 2.9.0a or later of the process (if this is not yet available for download, email firstname.lastname@example.org to get it.)
Next we'll look at adding structure, artifacts and gateways to our new patterns. Or check out the next article in the Using Scrum series: Participating in the Project.
