Change controls

Change control is based on a number of distinct roles for the persons on the development team, noted as follows:

Class owner

A class owner is the team member responsible for the integrity of a class in an application edition. Class ownership promotes the creation and maintenance of quality code, for the following reasons:

Class ownership provides the controls necessary for serious software development while offering the flexibility to let developers quickly experiment. The key is that only the class owner can release a class into its containing application. Other developers can create an edition of a class, change the edition, and even version the edition. The class owner, however, determines the main stream of development for the class through releasing.

Only a class owner can do the following:

The scope of class ownership is restricted to a single application edition. This means that where a class is defined in one application and extended in others, its definition and each of its extensions can have different owners. Further, if an application has multiple streams of development, the class might have a different owner in each stream.

Class developers

A class developer is a team member who develops and changes classes.

A class developer need not be the class owner. Unless restricted by access controls, any user can change a class and become a developer of the new edition or version. However, the class owner retains responsibility for ensuring that the released version of the class is correct.

A class developer can do the following:

  1. Load the edition into an image
  2. Create a version of a class edition
  3. Change the class definition
  4. Change a method (load, release, save, or delete)
  5. Change the public or private status of a method
  6. Change the comment or notes for the class

The second, third, fourth, and sixth items cannot be performed on versions. A new edition of the class must be created before such changes can be made.

Application managers

An application manager is responsible for the overall status of an application. An application manager coordinates the activities of the application's developers and ensures that the configuration information for the application is correct.

Only an application manager can do the following:

Configuration map managers

A configuration map manager maintains the integrity of a configuration map.

Only a configuration map manager can do the following:
