True as the author says in the introduction, the first three parts are the “meat” of the book. From how to generate an issue tree, to how to work with a team to solve a problem, to how to present results to clients, these are the marrow of the McKinsey Way and the resources we can benefit from.
As a seasoned intern having worked with several different big companies, most of the techniques and principles are not new to me. I believe it's even more so to those experienced professionals. But it's still a good handbook to keep, to remind yourself of some basics for an efficient and effective work. What’s more, if you can read with a humble heart or without any prejudices, I believe it will render out even more.
Though the author tries to be neutral and objective, the account in this book still “lifts a corner of the veil” of the dark side about consulting: long working hours usually into the early mornings, long and frequent business travels, complicated politics to navigate through at client organizations, and well-received yet reluctantly implemented recommendations…Any of these can take a toll on your health, relationships, and sanity. So think twice before choosing consulting. If you choose it, you choose a lifestyle.
