The book is based on research conducted at 13 different motion picture shoots through participant observation. The conclusions of the research establish a relationship between evolution of individual roles within teams and expression of new ideas within the team. The process of role evolution outlined in the book also shows how different stages of role evolution affects the fluency of expression of new ideas in a creative team. The book also talks about cumulative impact of role evolution of different individuals on overall creative output of the team. The book concludes by asking for devising new ways of assessing creativity of teams.
