The concurrent development model, sometimes called concurrent engineering The concurrent process model can be represented schematically as a series of major technical activities, tasks, and their associated states. For example, the engineering activity defined for the spiral model is accomplished by invoking the following tasks: prototyping and/or analysis modeling, requirements specification, and design. The activity-analysis-may be in any one of the states noted at any given time. Similarly, other activities (e.g., design or customer communication) can be represented in an analogous manner. All activities exist concurrently but reside in different states. For example, early in a project the customer communication activity has completed its first iteration and exists in the awaiting changes state. The analysis activity (which existed in the none state while initial customer communication was completed) now makes a transition into the under development state. If, however, the customer indicates that changes in requirements must be made, the analysis activity moves from the under development state into the awaiting changes state. The concurrent process model defines a series of events that will trigger transitions from state to state for each of the software engineering activities.
concurrent
Parallel development occurs when there is a need for separate development paths to diverge from a common starting point, so that there is no longer a single "latest and greatest" version, but instead two or more concurrent "latest" configurations (often called variants) where new development is carried on. Also implicit is the potential need for the divergent development paths to converge again. This means that any strategy for development branching should also take into account the process for merging.
