Certainly the importance of mastering project management, in particular for products that contain signficant amounts of software, is crucial for business success, both at Siemens and elsewhere. This book is based on extensive practical experience and is a broad and well-written book on this topic. The special focus on software architecture as a major success factor for projects provides a useful perspective -- not only for project managers but also software architects as well as others in the software development team.
