Iâve spent 20+ years failing forward as an entrepreneur, and have witnessed firsthand the evolution of entrepreneurship (innovation driven business creation) as a distinct discipline and skill-set, as well as the support and frameworks to aid and assist in creating more successful ventures.The problem:15-20 years ago, the only widely available resources were the Small Business Association (SBA), which focused on geographically focused businesses with well defined business models and low levels of innovation and uncertainty, and the Seasoned Core Of Retired Executives (SCORE) which paired execs from established businesses with business owners. There was a huge disconnect however, because neither of these organizations distinguished between owner/operators of well known enterprises, and entrepreneurs/founders of businesses with innovation as a core aspect of their DNA. It was a mess.Part of that mess was identified and discussed as methodologies and tools like agile development, lean startup, design thinking, etc emerged to articulate the specific differences between new businesses that operated with innovation as a fundamental and essential differentiator (with the accompanying uncertainty and attempts to mitigate/reduce it), and the well known models of established businesses---as well as why and how the processes and methods that work in established businesses--didnât work. Or, even worse, flat out will smother and kill ventures at that stage.But despite itâs popularity, Lean Startup hasnât delivered on the promise of less waste, more successful businesses. At least, not yet. Not any that can be easily witnesses or seen. Iâve had first hand involvement with TechStars and Y Combinator companies that have progressed from idea to full blown scalable, profitable, sustainable ventures, and each of these teams struggled with attempting to bridge the gap of theory to the daily grind of starting a business.Key issues they all faced;--Lean Startup exhorts identifying key assumptions and running fast experiments. OK, that might work for customer development, but does nothing to help ID customers and market segments (doesn't even meaningfully mention them). It does nothing to advance understanding customers, or ID'ing beachheads, determining financials (like market sizing), determining pricing, evaluating overall economics of the business . . .--Identifying and understanding discrete elements of a successful business.--Prioritization. (many/most had a sense of dependencies, but didn't know where to start in understanding what the elements were, or how they were related)--Application. (even if they had an idea of what they needed done, they wouldnât know *how* to do it)--Assessment/Diagnosis: Trying to understand how to interpret what was happening in their business. Struggling to zero in on what was causing the issue, discovering the ever elusive âwhy?âThis is the single most useful book with that regard. Itâs practical. It calls out the discrete elements in a very clear manner. And while thereâs a reduction of something immensely complex, that simplicity isnât due to omission. Itâs just base mastery of the subject matter.Several reviewers have suggested that this is a guide to help aspiring or new entrepreneurs. Maybe.Iâd suggest that this is actually much more useful to a sophisticated entrepreneur. Most of us have succeeded for reasons we canât articulate. We have hunches, and we kinda sorta know what we do, but we couldnât always explain it effectively. What this book does is provide a taxonomy for efficiently organizing and categorizing the âwhatâ of building a business. I, and many others whom I have shared this book with, had the experience of reading this book and recognizing things we have always done, organized into a precise framework. It instantly improved our thinking, and brought order to thinking and working that was otherwise disordered and sometimes flat out chaotic.Also, this framework does a damn good job of recognizing ACTUAL dependencies that rule the physics of all businesses, not the perceived physics (that favor the perceptions and skills of the founders). This lays out the must haves, in an order that is always true. Deviation from that sequential development is almost always going to cost you time and money.This framework isnât perfect. Itâs going to continue to evolve. That said, itâs my opinion that this is the single best example of the state of the art in Innovation Driven Entrepreneurship.Everybody can improve their business, tangibly, and in the very short term, through applying this framework and the processes laid out.Recommended without reservation.Buy it now.
