The document discusses how Microsoft's Visual Studio Team System (VSTS) helps development teams improve their application lifecycle management practices. It describes VSTS tools that enable teams to collaborate and communicate, manage workflows, drive predictability through process templates, ensure quality through testing tools integrated at all stages of development, integrate work frequently through version control and builds, and make real-time decisions using reporting. VSTS provides an end-to-end solution to support all roles from requirements to deployment.
