The problem of finding appropriate ways to organise and design organisational change processes, and especially their initial phases, is the main question behind this paper. It is argued that a methodological approach is advantageous by guiding the process towards efficiency and effectiveness. The theoretical base for such a method is described concerning change and method theory. Two methods deriving from perspectives of process redesign, quality, ergonomics and organisational theory were integrated. The resulting method was verified in three case studies, concerning change process and method use. The results show that integration of perspectives, situational adaptability, an unbiased initial problem attitude, and a change initiating co-operation between change agent and organisation could be achieved. The developed theory and work structures are advantageous in guiding and legitimising the change process. The work procedures ensure participation and enable both top-down and bottom-up generated improvements to be emphasised.
