I made lots of comments on the draft (up until p. 70) on crocdoc: <a href="https://crocodoc.com/g30tgl" rel="nofollow">https://crocodoc.com/g30tgl</a>. They should have been added by "Zach".<p>My general takeaway: You have something great here. I believe that what you have to say is largely valuable. Even if what you're saying isn't necessarily unique (in that it was derived from previous models), the way in which the book is framed <i>is</i>. The reconciliation of Customer Development and the Business Model Canvas with web-based startups is something that I've been looking for, and trying myself, since I read both books a few months ago. I look forward to Parts 2 and 3 (I believe they were omitted from this draft, yes?).<p>Two main points of constructive criticism:<p>- The structure of the book is problematic. Many of the headers and sub-headers are very similar, if not the same, which makes the book difficult to browse for content or to find your place. Furthermore, I believe that the chapters should be numbered. This would obviously conflict with your segmentation of the "Parts" of the book, but that could be rectified by using "Part A, Part B, etc.", and using numbers for chapters.<p>- There is too much summarization. I feel like there are topics that are first brought up in a list, then 10 pages later summarized in a more specific list, then 10 pages later expanded upon, then 20 pages later discussed upon in their own section (This is obviously hyperbole, but it's the feeling that I get). The introduction, for instance, begins with the section "What is Running Lean?" What immediately follows are a few paragraphs that the reader will naturally take as the answer to the proposed question. Running Lean, then, is "a systematic process for iterating from Plan A to a plan that works." But, near the end of the chapter, we are faced with a sub-section, also entitled "What is Running Lean?" From here we learn that Running Lean is <i>actually</i> the synthesis of "3 core methodologies: Customer Development, Lean Startup, and Bootstrapping". I suggest introducing <i>all</i> of this in the same spot. Reduce redundancy; reduce <i>waste</i>. :-)<p>I will keep adding comments as I read the book (they are mostly comments about wording/grammar issues), and will post here again if my general feelings towards the book change. For any clarification, my email address is available in my profile.<p>Best of luck!
