This can be considered a good introductory and light reading for any business person who is trying to make sense of the recent increase in mentioning of topics such as "data-driven culture", "big data", "data-drive decision making", "data literacy", "data-driven company", and such.
It gives a good overview, and can be mildly helpful for people who are trying to form a data strategy for their business, but one should not expect much from this book, because its structure is mostly like "here's what big company / my customer did with Y and Z type of data, and won big" repeated again and again in different business domains. Your company will of course fall into one of the mentioned business domains, but this doesn't automatically mean you can replicate a similar success. Nevertheless, the examples can be considered a good starting point to think about your particular use case.
For technically oriented people, there isn't much to learn about technology, except maybe a few mini case studies from some sectors and how the author manages to communicate the business value of these without frightening business people with technical and complex jargon.
Finally, I appreciated author's tackling the dark side of data: how companies should be careful with governance and privacy issues and why it doesn't make sense anymore to follow the worn out mantra of "let's store everything, we'll figure out later how to get value of that huge data set". This concern will be more and more important in the upcoming days, so whether you're the technical person implementing data related projects, or the business person responsible for the higher level data strategy, it'll be in your interest to take that part of the book seriously.
I also have to admit that, as a very technically oriented person who can easily dive into technological details, I found the book helpful to remind me how I can force my mind to look at things more from the business and high level perspective (and therefore I'll refrain from criticizing some of its inaccuracies when it comes technological points :) .
