Promotion Method
Topics
As the project progresses and the quality and stability of baselines improve.
A promotion level is an attribute of a baseline that is used to indicate its
quality or stability. Baseline attributes and levels can be defined by the
project, however, some example promotion levels are the following:
- Integration Tested
- System Tested
- Acceptance Tested
- Production
The levels are ordered to reflect progression from the lowest to the highest
quality. The act of changing the promotion level of a baseline is called
promoting or demoting the baseline.
On occasion, the configuration manager may need to demote a baseline by
changing its promotion level to one that is lower in the promotion level order.
For example, the integrator may discover a a major bug in a newly created
baseline. To prevent developers introducing this bug into their development
workspaces, the baseline could be labeled as rejected.
The recommended baseline represents a system configuration that has achieved
a specific promotion level. A baseline becomes part of the set of recommended
baselines when it is promoted to a certain level, for example, TESTED. Promotion
levels can be used in project development policies. For example, a project
policy could state that a given baseline is the recommended baseline when it
reaches a particular promotion level. This policy helps to ensure that
developers rebase their work areas whenever a baseline passes an acceptable
level of testing.
