Prototyping revisited

A discussion is presented of the different standpoints which, at the beginning of the eighties, have brought forth prototyping as a strategy. The different lines of development are sketched, and the various trends are examined. An examination is made of the following topics: (1) the history of prototyping and the software crises, (2) prototyping terminology, (3) trends that have supported prototyping, (4) methods in line with the idea of prototyping, (5) areas of research and development that will help to promote and develop prototyping, and (6) integrating prototyping into the concept of evolutionary systems development
