Our decisions shape who we are and the reality we live in. The stakes are high because our decisions will play a large part in determining if we succeed or fail. Each of us makes dozens of decisions every day, thousands of decisions a year. Whether you are planning a solo venture or you’re part of a young start-up, you need to cultivate an unfair advantage to overcome the odds of failure as you are blazing a new path. Programming decision rules and processes into your life or your organization’s culture can accelerate learning and give you that advantage. I wrote this handbook for my team at Reach Labs to help us make better decisions. When businesses utilize the decision-making processes, rules, and tools described in the handbook, they can increase their rate of learning, create tighter feedback loops to make decisions more quickly, and build systems to improve performance.
