Best Books for Consultants

A consultant is paid for two things: seeing the problem clearly and getting other people to act on it. The best books for consultants cover both halves, the thinking and the persuasion, and most consulting books only cover one.

This list is six books. Each links to a synthesis that cuts the book to the 20% you can use in your next client conversation, with a "do this today" step and three prompts to run on a live engagement.

Why consultants need the 20%, not the whole book

Consultants already read a lot. The problem is that reading doesn't turn into models you can reach for in a meeting. A synthesis gives you the model in a form you can remember and explain to a client in two minutes.

The books split into two groups. Thinking, Fast and Slow and The Art of War are about diagnosis: spotting the easy question a client swapped in for the hard one, and knowing the terrain before you commit to a recommendation. How to Win Friends and Influence People, The 7 Habits and Start With Why are about the room: listening first, letting the client reach the conclusion, and leading a proposal with why it matters. The 48 Laws of Power covers the politics in between.

How to use this list

1. Match the book to the engagement. Messy diagnosis: Thinking, Fast and Slow. A sceptical stakeholder: How to Win Friends. A proposal that keeps losing on price: Start With Why.
2. Read the synthesis before the meeting, not after. Each is a few minutes.
3. Run one prompt on the live problem. Paste in the real brief, with client details removed.
4. Keep the model, drop the book. If you can explain the idea to a client in two minutes, it's done its job.

The consulting books that didn't make the cut

This page only lists books the site has actually distilled, so every link goes to a full synthesis. Classic consulting titles will be added as they get one.
