Ashley Moran wrote a wonderful review of Manage Your Project Portfolio. I particularly like these quotes:
There’s a wealth of tips for making the whole process effective, with some unexpected ones thrown in. The sections How to Kill a Project and Keep it Dead and Discover Barriers to Collaboration are little gems.
It’s also amazing that all this has been fitted into just 170 pages. You could read it in a day.
Essential reading for software managers, and extremely valuable to anyone in working software who is committed to helping their team deliver customer value while staying sane in the process.
