The integration of ergonomics in design and planing has always been an ambition within ergonomics, but experience show that it is an ideal difficult to bring into practice. Presently tools, methods and procedures are asked for. This paper argues - by presenting an overview of existing recommendations - that this is not actually what presently is needed especially not form research and development. It is suggested that a better understanding of change processes in organisations and especially of the role of the change agent is needed, and an understanding based on understanding organisations as political arenas is advocated.
