A prototype is used to check feasibility (also called proof of concept), specific system behavior or a system feature.

The realization of a prototype is a risk-reduction measure. Depending on the project situation, prototyping can occur in different phases, once or more times. A prototype can be reusable or disposable. Depending on the findings, the next steps are determined.

The objectives, the concept and the outcomes of the prototype are recorded in the prototype documentation.

The prototype is developed and the prototyping outcomes are evaluated.

1. Develop the objectives, concept and methodology for the prototype
2. Realize prototype
3. Evaluate prototype
4. Document outcomes and conclusions, and incorporate them into further planning
5. Destroy prototype or ensure reusability
