Process Models To Represent Phases

A process model is a way to represent each phase of a software project and is characterized by :

1. Entry criteria specifies when the phase can be started. Inputs for the phase are also included. A clear entry criteria makes sure that a phase doesn't start prematurely.
2. Tasks or steps that need to be carried out in that phase.
3. Verification specifies methods of checking that the tasks have been carried out correctly. Helps in defect prevention and delays the time gap between defect injection and defect detection.
4. Exit criteria specifies conditions under which one can consider the phase as done. Outputs are also included. This model is known as the Entry Task Verification Exit or ETVX Model.

Life Cycle Models

A life cycle model describes how the phases combine together to form a complete project or life cycle. Such a model is characterized by the following attributes :

1. The activities performed
2. The deliverables from each activity.
3. Methods of validation of the deliverables.
4. The sequence of activities.
5. Methods of verification of each activity, including the mechanism of communication amongst the activities.

Some Life Cycle Models

1. Waterfall Model

2. Prototyping & Rapid Application Development(RAD) Model

3. Spiral or Iterative Model

4. The V Model

5. Modified V Model
