This article introduces development and design approaches to organizational change (DIL). Simulation games can be used for promoting organizational development. They offer an arena for organization members to analyze the present state of an organization and create new organizational solutions. The bridge between the present and future mode of working can be built on by the ideas for improvement brought forward by the participants of the simulation game. The study focuses on the WORK FLOW GAME (WFG) (DIS). It integrates the following activities: work process improvement, use of information technology, and participation and learning by the personnel of a company or public agency. WFG promotes organizational innovations through interaction and cooperation of the people involved.
