A comparison of Process State Table (ProST) and scenario on making concepts and drawing requirements for logical GUI design

Abstract

Concept and requirements are detailed together. Actually, concepts can’t be almost defined before visualizing ideas. Ideas of products can be visualized by sketches or/and models. However, there are few tools to visualize services, user interface and other invisible things. ProST and scenario are the tools to image the context of use and the usage of invisible things. ProST was compared with scenario on making concepts and drawing requirements for logical GUI design.
