I was lucky enough to have some I’d been a part of captured in a case study. The engagement was focused on Application Lifecycle Management improvements focused on people, process and tools (TFS).
The study is available at http://www.microsoft.com/casestudies/Case_Study_Detail.aspx?CaseStudyID=4000004473
When I work with a customer I’m most successful when I embed myself in their org. This helps me understand the nuances of the problem but also craft a solution that is appropriate to the organization. With a deep understanding of the organization an engineering solution can be developed that persist people and organizational changes.
