What are the software development models?

(1) Waterfall Model: Waterfall model The software life cycle is divided into planning, requirements analysis, software design, coding, testing, maintenance six stages, in a fixed sequence of software development.

(2) Rapid prototyping Model: developers build a rapid prototype for customer evaluation, further identify requirements, once the requirements are determined, can abandon the established prototype.

(3) Incremental model: The incremental model considers software as composed of a series of incremental artifacts.

(4) Spiral Model: The spiral model combines the waterfall model and the rapid prototyping model, along the Helix several iterations, which is driven by risk, that is, the risk analysis must be carried out before a certain stage is implemented.

(5) Hybrid model: Mix several different models, which allow a project to evolve along the most efficient path.
