What does ChaRM provide, and what two things does it combine?

A framework/workflow/capabilities to manage landscape-wide change. It combines:

• A governance body — guiding the change + release processes.
• The technical mechanism — pushing physical transport requests from system to system.

Resource management, project planning, and release coordination are integrated out of the box; it's built on SAP CRM business transactions with a Web UI, is ITIL-conformant, and needs almost no config.
