The book refers to the relation between biography and interaction. Coaching as a specific situation of professional communication reflects this relation. The qualitative method of research sets out to be innovative in the way it combines historical, i.e. biographic approach and an interactive, actual approach. As a result, it shows great evidence of the convergence between biography and interaction. How do biographic structures influence communication in general and coaching in particular? How does the coaching interaction mirror biographic resources? What does that mean for the process of learning coaching?
