Differences and linkages between several major development models

The difference: Waterfall model is a linear model, each stage must complete the required documentation, suitable for the needs of clear and stable small and medium-sized software development.

Rapid prototyping user intervention is premature, through iterative refinement of customer requirements, prototype obsolescence, suitable for small-scale software development with fuzzy requirements.

Each iteration of the incremental model completes an increment that can be used for OO development and is suitable for large-scale software development that is easily chunked.

Spiral model is a typical iterative model, which takes risk analysis as well as OO development, and is suitable for large-scale software development with uncertainty.

Fountain models are object-oriented iterations and seamless or refinement.

Contact: The main task is to summarize the user's needs, in order to concisely describe the process of software engineering, they are summed up in the demand analysis.
