Disclaimer: I received this book as a complimentary copy in exchange for an honest review.
About me: I am a Data Scientist at an NYC Fintech, with 4 years of experience applying AI/ML in the financial sector. On a daily basis, I deal with key stakeholders from the rank-and-file ops user, to senior management at major global banks.
Review:
Here's a book that's easy to read but tough to review. It presents the problem of working with and making sense of data in 6 phases:
1. Ask
2. Acquire
3. Analyze
4. Apply
5. Announce
6. Assess
The above is pretty accurate, and an excellent way to think of data-related problems. Each of those are broken down into sections where the author develops his thesis, providing great examples along the way to cement the material.
One can easily tell he is a great educator from the way he handles difficult concepts and makes them accessible without being patronizing. In that, he is also thorough.
My major gripe with the book, and the reason I only gave it 4-stars, is that I am at a loss as to who this book was intended to serve. Depending on the audience, it could be: (perfect!), (too technical), (not technical enough), (too long).
The first 5 chapters are, in all honesty, great! Having been part of implementation teams at large financial institutions, I always found myself going through the steps outlined therein and explaining the same concepts as the author (albeit less brilliantly) to senior management and low-level stakeholders. In that sense, these five initial chapters are invaluable for anyone trying to explain the problem of extracting value from data and how to go about it from a completely methodological standpoint. So, perfect if you need to talk to (busy) managers that only need to get the overall picture and buy into it, as well as the ops users that will be implementing these first steps.
From here on, I became a bit lost in the scope of the material. Chapters 6 ("The Analyze Phase") through 9 ("The Apply Phase") are a mishmash of things that seem a bit Frankensteinian. For instance, if you read and found the first five chapters useful, you would not expect the author to tell you about means, standard deviations, and the normal curve in chapter 6. It's a bit too basic for that audience (and probably any audience of this book) and probably does not belong here. Chapters 8 and 9 are a bit too psych-101, filled with too many principles and "rules" that are redolent of popular science books. In short, too "bloggy".
Fortunately, the author managed to bring it in for a strong finish in the latter chapters, providing useful tools, frameworks, models, templates and job-aides that will surely benefit his audience. The last chapter in particular ("Example use cases and case studies") is brilliant as it presents the overall picture without any of the fluff. I loved it!
Overall, I think this book would be useful to anyone looking to make informed, data-driven decisions, or are working closely with those that will. Recommended.
