Kinds of process model :

• concurrent engineering model (4 facts) - A process model in which each team works on its own component, typically following a spiral or evolutionary approach
• evolutionary model (5 facts) - A process model that views development as a series of hills, each representing a separate loop of the spiral model
• extreme programming (9 facts) - A process model and methodology that provides a disciplined approach to highly incremental and user-centred development of small projects
• incremental development (3 facts) - A process model in which the software is developed in a series of releases
• opportunistic approach (4 facts) - An unsatisfactory process model in which developers keep on modifying the software until they or their users are satisfied
• phased-release model (7 facts) - An approach to incremental development in which, after requirements gathering and planning, the project is broken into separate subprojects, or phases
• spiral model (6 facts) - An incremental process model that explicitly embraces prototyping and an iterative approach to software development
• waterfall model (10 facts) - A process model in which the software engineer works in a series of stages
