Book excerpt: A project manager who doesn't make mistakes is a project manager who never progresses. Making new mistakes is a sign of growth and advancement. However, repeating past errors or failing to learn from those made by others is a definitive path to sabotaging one’s career. Explore this rigorously researched compilation of 101 mistakes that project managers routinely commit across domains, industries, and cultures, and understand the “why's” and “how not's” of each of these mistakes. You will be better equipped to scrutinize those mistakes you may make without realizing. While there are many books that tell you “what to do” when it comes to project management, this is the only book that tells you “what not to do”. This compilation would help project managers, function heads, project leaders, sponsors and senior management / leadership engaged in the world of project and program management.
