A practical guide to building high-performing teams

A talented group isn’t automatically a team.

Most teamwork advice tells you what good looks like — not what to do when your team doesn’t. This book helps you find which problem you actually have, and fix that first.

How to Teamwork by Reinier Jansen, book cover

How to read this book

Don’t read 14 chapters. Start with one question.

You have one team, one set of symptoms, and limited time. Skip straight to what matters — come back for the rest later, or never.

1

Ask the Gate Question

Ask each person separately: “What is our team’s goal, in one sentence?” Different answers? Go to Chapter 2.

2

Run the Symptom Scan

Mark only what you’ve actually seen in the last two to four weeks.

3

Fix one lever

Pick the symptom costing you the most. Read that chapter. Give it two to three weeks.

4

Re-run in a month

Symptoms shift once you fix the first one. That’s expected.

The Symptom Scan

Which of these have you seen lately?

Not generally — in the last two to four weeks. Each symptom points to a likely cause and the chapter to read first.
