The Big Con: How the Consulting Industry Weakens our Businesses, Infantilizes our Governments and Warps our Economies by Rosie Collington, Mariana Mazzucato

Did not finish book. Stopped at 55%.
After reading an interview with the authors and book's release notes, I was really keen on learning how, why, where and when employing consultants is detrimental to the client. 
Disclosure: I do work in the industry, one company I worked for is mentioned briefly around page 40%.
The book in the first half I have read keeps providing examples of projects going wrong, but shies away from looking into the reasoning behind the decisions  made, or finding similar projects that went much better under different circumstances.  
Feels like it is just a binder of random case studies - but it is hard to say how were they chosen, why are they mentioned and they aren't too thoroughly researched.
