ADDIE, A top-down design methodology:
Analyse > Design > Develop > Implement > Evaluate
Rapid prototyping
This methodology differs in that simple, prototypes are developed and trialled with learners as part of the design process, rather than implementing all the course at the end of the development phase. This is a more flexible and dynamic approach than ADDIE, and resembles the approach we've taken in Project 1. For a comparison of ADDIE and the rapid prototyping approaches, see e-learning guru
