This book is truly a tome of Strategic Analysis and Strategy in general but it is also an incredible guide and reference for ongoing work. Michael Porter is considered the Grandfather of Strategy and Strategic Analysis in the 21st century. His various works are considered, in some form or another, as required reading in any MBA course on Strategy and leadership. I was first exposed in my Master’s of Science program at Purdue, through their partnership with Thunderbird School of Global Management. His article, included in Harvard Business Reviews “Top 10 Must Reads” On Strategy, titled “What is Strategy?” merely glosses the surface. Porter my brother as an Industrial & Systems Engineer by another Mother as this book is a thorough “systems thinking” analysis and framework of industry’s, markets, business structures, and ultimately understanding their evolution as well as where the profit (and power) currently resides in a market and where it is likely to reside in the future. I recommend this book for anyone seriously interested in the foundations of Strategic Thinking but also Industrial & Systems Engineers, Innovation Leaders and Leaders in General, as well as entrepreneurs looking to have a framework from which to understand the current and long term structure of their industries.
