  • Waterfall Model: The basic development activity is regarded as a series of distinct independent stages, which is a kind of program-driven software process, which is helpful to standardize software development activities.

  • Prototyping: A prototype is a partially developed product that strengthens the understanding of the system, helps clarify requirements, and selects viable design strategies.

  • Iterative development: combine different activities, such as description, development, and validation, to build a series of versions during the development process and to progressively deliver parts of the system.

  • Convertible Model: use automated means to transform requirements specifications into a system that can be delivered using a series of transformations.
