Development Tracks 
A development track contains
· all development configurations and
· all runtime systems
that are needed to develop, test, and produce one or more software components.
Development configurations contain information about dependencies between software components, and the assignments between DTR workspaces and CBS buildspaces. (See also Development Configurations).
Runtime systems are systems in which you can test and use your software components in a runtime environment.
A development track now contains the development configurations and runtime systems for the various development states of the software component. These are usually:
· DEV (development)
· CONS (consolidation)
· QA (quality assurance)
· PROD (production)
The software component goes through all of these states during its lifecycle. The Change Management Service (CMS) propagates the component from one state to the next.

These development states can differ according to the way the track is used. The states listed here are taken from the current track template for development.

The graphic below is a schematic representation of a development track and its development configurations and runtime systems.
