What is a Change Package?

The heart of ChangeMan ZMF is the change package. A change package is a unit of work within a software development or maintenance project. It is managed as a unit through a defined lifecycle while software changes are in motion.

A change package consists of descriptive information, control parameters, and history information stored in VSAM files. It also includes a set of libraries that belong exclusively to the change package and which contain the software components being changed. A change package is a secure development environment for project components, with access managed by ChangeMan ZMF using rules stored in your security system.

A change package and the components in the package are guided through your system development lifecycle by the ChangeMan ZMF package lifecycle.
