The audience approaching these books usually has two origins: industry and academia. On the industry side, one wants more information on how to do it. From the academic side, more about the concepts, and what they mean.
In this sense, the book tries to offer a bit to both, on the one hand, it explains, and well, the conceptual components of narrative design, on the other hand, it gives an account of teamwork processes. Naturally, it does not go into depth. Nor does it give an account of the tools, and how to overcome the most complex problems, sought by those working in the industry. Nor does it establish any relationship with the issues of narratology, in the sense of sustaining in-depth the scope of the importance of the design of a narrative as opposed to just the writing.
An interesting, even if introductory, book.
