Document Summary

Prototyping is a half method and takes an intermediate place between the sdlc and the lean methods. Prototyping, as an iterative process, can better protect against the potential catastrophe attendant upon finding the elephant. Prototype is also often used to try our improvements to a system that were not part of the original specification but which occurred to the developers in the process of building. Step 6 is crucial and is all about user feedback. The prototyping process for software development: project inception and feasibility, perform a basic requirements analysis (not as in-depth as in the sdlc, prototype is developed, often only including user interfaces in the earliest stages. This is referred to as horizontal prototyping: the current prototype is shown to the clients to elicit feedback, the feedback is used to revise and enhance the prototype. Continuing this loop until a deliverable system is produced.
