Windows 7 isn't the only major product due out this fall from Steven Sinofsky. The Microsoft Windows president has been working as a co-author on a book with Harvard Business School's Marco Iansiti, a Microsoft representative confirmed this morning. The book is expected to draw in part on Sinofsky's experience, coming in to lead a complex organization and focus it on a unified vision.

Barnes & Noble refers to the book under the working title, "One Strategy," but we hear that the title has not been finalized. Here's how the bookseller describes the book in an abstract.

This book is about developing and executing great, innovative strategies. It shows general managers how to build the right organizational capabilities and base of understanding, how to generate insightful strategies and develop detailed plans, and how to lead these strategies to completion. The book is founded on 20 years of Harvard Business school research on strategy and innovation (Iansiti) and 20 years of management experience at Microsoft (Sinofsky). The central evidence for the book is drawn from the extensive blogs written by Sinofsky to manage his 4000 person Windows and Windows Live organization, as it recovers from the Vista challenges and embarks on a new strategic direction. The book focuses on Sinofsky’s quest for building an integral enterprise, restructuring the Windows Group to preserve and improve upon a business worth $10’s of billions in revenues, and over $100 Billion in market capitalization. Two and half years old, the quest is already showing signs of success, with significant achievements in organizational satisfaction and product shipments.

The big question, of course, is whether Sinofsky's book will outsell former Windows chief Jim Allchin's album.
