The goal was to our clients in the insurance industry. The program resolve all clarifications within the Sprint teams, appeared to be going in circles and was conspicu- as speed was required. ously stuck in requirements and analyses. It was not until late July when it was decided to move the program to an Agile/Scrum approach; the Original Sprint Teams plan was to get the program back on track for a delivery in May 2012. As expected, numerous On-site Offshore questions were raised. Among them: How long Sprint Lead Lead/ Proxy Sprint Lead should the Sprints be? How do we put a backlog Scrum Master together quickly? How do we get the teams to be Business Analyst Business Analyst productive as soon as possible? Do we include testing within the Sprint teams? How do we finish Lead Tester Tester the analyses of the outstanding requirements? UI Architect Service Architect Etc., etc., etc. Not Applicable Five Developers Time was of the essence.
