Every year billions of dollars are invested in businesses launched to bring new inventions into the market. Unfortunately, many of these businesses fail due to the inexperience and poor judgement of their leaders. The Inventor's Puzzle deciphers the business of product innovation and exposes essential issues that can lead to business failure when evolving an invention from concept to market-ready product. Rather than presenting these issues from a distant academic perspective, The Inventor's Puzzle is written from the author's firsthand experience of troubleshooting real-world problems in product innovation businesses. The book serves as a "how to" guide and a business primer for the myriad of product innovation stakeholders, including inventors, entrepreneurs, and investors, who are drawn to this dynamic business sector but who might lack firsthand experience.
