A refreshingly good overview of the EA field, that manages to discard a lot of the often jargon-filled texts that exists. And the author manages to stay fairly neutral when describing the evolution of the EA field.

if you want to understand what EA is about, including its drawbacks, this is a recommended book, with a lot of examples, that even manages to explain a lot of the concepts that you will need later, if you want to deep-dive.

Unfortunately, I agree with the author that EA is very needed but seldom used, due to the overly complexity of the field (and sadly, Powerpoint is more often used to present complex ideas to management)
