I have collaborated with Microsoft through my company CEI to create a new process template for TFS. It is tailored to Government clients that have requirements like CMMI, but also want to be agile. The main work item we have added is a Use Case. It is intended to be the child of Requirement work items and replaces the User Story work item in the Agile template. Many of the work item queries from the Agile template have been integrated into the GovDev Process Template. The following graphic nicely shows how the linking between work items is intended to be done.
One of the most significant reports added was the Requirements Traceability Matrix! I have heard many clients ask for this in the past, especially in regards to government requirements. A screenshot is given below.
The best part is this is all open source! Here’s the link to the Codeplex site, go download it today!
