Answer:
Explanation:
Concurrent Process model can be regarded as evolutionary process model as well as software engineering is concerned, it allows to know the current state of activities as well as their associated states.
The set of states In the concurrent process model are:
✓awaiting changes
✓Inactive
✓baselined
✓under development
✓under revision
✓under review
✓done
The stated "states" above give a representation of externally observable mode as regards to the behaviour of activities of a particular software engineering.
The existence of activities of software engineering do exist at same period
In concurrent process model, though each of the activities occur in different states so that process network is produced. The movement from one state to another of activity of software engineering is as a result of
predefined events.
