This book opens a view into the dialogical methods used in national policy programmes and in local action research projects in Finland. On the basis of versatile academic and facilitator experience the authors shed light on the theoretical-philosophical backgrounds of the methods and analyze the prerequisites and the challenges of dialogue in case studies in different work environments – from day care to new technology. Dialogue is seen both as episodic situations and as continuous processes that may promote the quality of working life and the effectiveness of organizations. The creation of permanent development structures by using dialogue as a driver of learning, action and change is proposed to be one of the most challenging aims of the research-assisted development activities.
