About the book
Every organisation’s trajectory is shaped by a tiny fraction of its decisions — the 1% that are irreversible, high-stakes, and often invisible until it’s too late.
Why even the most brilliant leaders and talented teams botch critical decisions, obsess about inconsequential ones, or land on compromises that nobody believes in but nobody cares to object to? This book explores the reasons from psychological biases to systemic failures. More importantly, it provides a comprehensive toolkit for building the decision-making culture and disciplines that ensure organisations consistently make more good choices than mediocre ones. Over time, that edge compounds into extraordinary performance.
Drawing on 20+ years of real-world strategy through execution experience across complex enterprises in financial services, energy and health, Maxim Sharshun introduces the practical 50:1 Method.
This is a battle-tested executive toolkit built on the 50:1 Rule (where 1% of choices drive 50% of outcomes), 1% Frontier and Decision-Making Pyramid frameworks, that help identify those critical choices, and a comprehensive Who-How-Why-What toolkit for consistently nailing those.
