Many development teams inside Microsoft are now using the agile methodology for software development and had been looking for a way to track their daily progress. Some of the product units in Developer Division are also using this methodology.
A team within Microsoft decided to build a web based tool on top of Visual Studio Team Foundation Server for just this purpose. Seeing the excitement and adoption for this among internal teams, our services folks (Microsoft Consulting) wanted us to make this available broadly to our customers. As a result, eScrum 1.0 was released today on MSDN for external consumption.
This tool integrates with Excel and MSProject via TFS, allows interaction with TFS Team Explorer, and is a one-stop place for all Scrum artifacts such as product backlogs, sprint backlogs, task management, retrospectives, and reports.
