In this article a methodology for rapid prototyping is described. Modified data flow diagrams are used as a graphical tool and Prototyping System Description Language is deveoped.The advantages of the methodology and of the prototyping tool, which is being built, are as follows: a possibility to describe a system in an understandable graphical way without global data, a posibility to describe the system by parallel activities and a possibility to verify the whole system or only a part of it. A simple and understandable specification of the new system is enabled by decomposition.
