Coaching for Performance, Fifth Edition (25th Anniversary Updated Edition): The Principles and Practice of Coaching and Leadership

Introduction

Coaching for Performance by Sir John Whitmore is widely regarded as the definitive guide to coaching in business, leadership, and life. Now in its fully updated 25th Anniversary Fifth Edition, the book reflects the evolution of coaching from a niche leadership skill into a core organizational capability. Whitmore introduces and expands on the renowned GROW model, providing a practical, human-centered framework for unlocking potential and improving performance through awareness, responsibility, and trust.

This updated edition of Coaching for Performance integrates modern leadership challenges such as employee engagement, sustainability, and purpose-driven organizations. Rather than focusing on command-and-control management, Whitmore argues that high performance comes from asking better questions, fostering ownership, and creating environments where people think for themselves.
