Abstract:

Prototypes are often used as a tool in the product development process and their usage is advised in many guidelines, frameworks and product development methods. Those prototypes achieve different goals of which most relate to getting new insights and information about the product in development. For the development of those prototypes however, significantly less development methods are available compared to the number of methods for the development of products. Investigating the process of using a prototype leads to the idea that the main purpose of those prototypes is describable as learning about the product. This idea is elaborated further and followed by the introduction of the detailed process model for prototyping which is primarily based on the detailed process model for products. However, the purpose of the prototype differs from the purpose of the product which leads to some significant changes of the model. To give an example of a prototyping process, the development of a sensor-integrating elastic claw coupling is introduced and analysed. In addition, this paper discusses the question, how other product development models may be applied to the development of prototypes.
