Multipliers

Introduction

Liz Wiseman, a former executive at Oracle, studied leaders and noticed that some made everyone around them smarter and more capable, while others drained intelligence and energy. She calls the first group 'Multipliers' and the second 'Diminishers'.

Multipliers, written with Greg McKeown, describes the five disciplines that distinguish them and how leaders can become Multipliers.

Who should read this book?

Managers, executives, teachers and anyone who leads others and wants to get the best from them.

Helps with: Lead and grow at work

The central message

The best leaders amplify the intelligence and capability of their people. By acting as Multipliers, leaders get more from their teams.

Key ideas and concepts

1. The Talent Magnet

   Multipliers attract talented people and use them at their highest point of contribution, while Diminishers hoard resources.

2. The Liberator

   Multipliers create intense but safe environments that require people's best thinking.

3. The Challenger

   They define opportunities that stretch people rather than giving all the answers.

4. The Debate Maker

   They drive sound decisions by encouraging rigorous debate.

5. The Investor

   They give people ownership of results and hold them accountable.

6. The Accidental Diminisher

   Well-meaning leaders can shrink others by being too quick, too helpful or too full of ideas.

Deeper analysis

Multipliers offers a practical lens for leaders to examine their impact on others. Wiseman's five disciplines are clear, and her concept of the 'accidental diminisher' is especially useful because it shows how good intentions, like jumping in with ideas or rescuing people, can suppress others' thinking.

The research is based on interviews and consulting work, and claims such as Multipliers getting twice the capability from people are hard to verify independently. The book is somewhat repetitive. Still, it's a helpful tool for self-assessment and for developing leaders.

Practical applications

• Ask more questions and give fewer answers in meetings.
• Give someone ownership of a project.
• Set a stretch challenge for your team.
• Notice when you're being an accidental diminisher.
• Invite debate before decisions.
