Software Process Model

Software process model is a Software Development Life Cycle model or Software Paradigm. Software Development Life Cycle (SDLC) model is a diagrammatic representation of various activities required to make software product. Along with this diagrammatic representation description of each phase of the SDLC must be given. The software life cycle also specifies the order in which each phase must be executed. There are various life cycle models and those are:

1.    Waterfall model

2.    Prototype model

3.    Spiral model

4.    Evolutionary development model

5.    Iterative enhancement model

The basic activities that can be carried out in life cycle model are:

1.    Feasibility study

2.    Requirement analysis and specification

3.    Design

4.    Coding

5.    Testing

6.    Maintenance

These are typically called as phases of life cycle model.
