The post proposes a six-stage process that addresses two key challenges: balancing intuition, experience, and data as inputs, and creating a feedback loop that studies the decision itself rather than just the outcome. The stages begin with defining the dilemma and establishing a default decision—what you would choose immediately—then ask what evidence would change that choice, research that evidence, identify a set of meaningful alternatives, and make a risk-versus-reward decision with documented rationale.

## Summary

According to research by Wal McConnell and Lynsey Duncan, quick decision-making is a startup’s biggest competitive advantage, but it is often dismissed as reckless. The post proposes a six-stage process that addresses two key challenges: balancing intuition, experience, and data as inputs, and creating a feedback loop that studies the decision itself rather than just the outcome. The stages begin with defining the dilemma and establishing a default decision—what you would choose immediately—then ask what evidence would change that choice, research that evidence, identify a set of meaningful alternatives, and make a risk-versus-reward decision with documented rationale. Finally, the process requires reviewing both the outcome and the decision quality, independent of the outcome, to extract learnings and improve future decisions. The approach advocates breaking large decisions into smaller experiments, continuously reviewing assumptions, and iterating quickly to maintain agility and momentum.

## Context

Published on the Intercom blog, the post draws on research conducted with Lynsey Duncan and references concepts from Cassie Kozyrkov, Google’s Chief Decision Scientist.

## Approach / What changed

A six-stage process: 1) Define the dilemma and desired future; 2) Determine a default decision based on current knowledge, intuition, and experience; 3) Ask what information would change the default decision and conduct targeted research; 4) Identify a set of meaningful decision choices; 5) Assess each choice on risk versus reward, document the rationale and assumptions; 6) Review both the outcome and the decision process independently to improve future decisions.

## Takeaways

- Effective quick decision-making balances intuition, experience, and data as inputs, not relying solely on facts or analysis.
- Establishing a default decision early creates a benchmark that prevents aimless information gathering and speeds up the process.
- Reviewing the decision process separately from the outcome reveals blind spots and assumptions, providing more reliable learning than judging by results alone.

## FAQ

### What is a default decision?

It is the decision you would make right now without additional evidence, based on your current knowledge, intuition, and objectives. It establishes a benchmark for evaluating new choices and prevents broad, inefficient information gathering.

### How do you know if more evidence is needed?

Ask yourself what specific information would steer you away from your default decision. If no such information exists, you can proceed; otherwise, convert that into a targeted research question to reduce uncertainty.

### Why review the decision separately from the outcome?

Because good outcomes can result from luck, and bad outcomes from sound decisions. Studying the decision process, assumptions, and blind spots provides more reliable learning for improving future decisions.
