Waiting for perfect information is a decision to lose.
The 70% rule states that most business decisions should be made with 70% of ideal information and 70% confidence in the outcome. Decisions delayed beyond this threshold cost more in lost opportunity than imperfect decisions cost in correction. Speed of decision beats quality of decision in most business contexts.
I call this The 70/70 Decision Protocol—a rapid-fire test that eliminates analysis paralysis. After watching decision delays destroy millions in value at Berkshire Hathaway, Illinois Tool Works, and Whirlpool Corporation, I developed this framework to force action over deliberation.
What Is the 70% Rule in Decision Making?
The 70% rule in decision making requires acting when you have approximately 70% of the information you’d ideally want and 70% confidence you’re choosing correctly. Additional information gathering beyond this point yields diminishing returns while opportunity costs accelerate.
Here’s the uncomfortable truth: the information you’re waiting for probably won’t change your decision. Research from Harvard Business Review on decision quality found that decision accuracy peaks at 60-70% information availability, then remains flat or declines as analysis paralysis sets in.
The math works against perfectionists. If you wait for 90% information, you’ve consumed 3x the time for marginal accuracy improvement. Your competitors made three decisions while you deliberated on one.
Jeff Bezos articulated this principle: most decisions are reversible “two-way doors.” Treat them as such. Make the call, observe the outcome, adjust if necessary. The cost of correction is almost always less than the cost of delay.
How Do You Apply the 70/70 Decision Protocol?
Apply The 70/70 Decision Protocol by asking two questions before any decision: “Do I have at least 70% of the information I’d ideally want?” and “Am I at least 70% confident this is the right choice?” If both answers are yes, decide immediately. If not, set a deadline by which you’ll decide regardless.
Execute this protocol in practice:
- State the decision required in one sentence
- List what information you have (not what you’d like to have)
- Estimate your confidence level: below 50%, 50-70%, or above 70%
- If above 70% on both tests, decide now
- If below, identify the single piece of information that would most change your confidence
- Set a deadline to obtain that information or decide without it
The deadline is critical. Without a forcing mechanism, analysis continues indefinitely. Most organizations default to “gathering more information” as a way to avoid commitment.
Why Does Decision Speed Matter More Than Decision Quality?
Decision speed matters more than decision quality because business environments change faster than analysis cycles complete. A good decision made quickly beats a perfect decision made slowly. According to McKinsey research on strategic decisions, organizations that decide quickly outperform deliberate competitors by 2-3x on key metrics.
Consider the learning cycle advantage. Fast decisions create rapid feedback loops. You discover what works through action rather than prediction. Organizations making 10 decisions while competitors make 3 accumulate 3x more learning—and learning compounds.
The only decisions requiring more than 70% certainty are irreversible ones with catastrophic downside. These represent perhaps 5% of decisions any organization faces. The other 95% should be made fast and corrected fast.
What Decisions Require More Than 70% Certainty?
Decisions requiring more than 70% certainty include irreversible commitments with catastrophic downside potential: major acquisitions, facility closures, market exits, or senior leadership changes. These “one-way door” decisions warrant extended analysis. All other decisions should follow the 70% rule.
The test is simple: Can this decision be reversed or corrected within 90 days at acceptable cost? If yes, apply the 70% rule. If no, invest in additional analysis—but set a hard deadline even then.
Most leaders over-classify decisions as irreversible. They treat hiring decisions, product launches, and pricing changes as permanent when all are reversible. This misclassification creates false caution that destroys velocity without improving outcomes.
Stop waiting. Start deciding. Correct as you go. This is how winners operate.
Frequently Asked Questions
How Do You Build Organizational Confidence in Fast Decisions?
Build organizational confidence in fast decisions by celebrating quick decisions publicly regardless of outcome, creating post-decision reviews focused on learning rather than blame, and modeling rapid decision-making at leadership level. Confidence comes from repetition and positive reinforcement, not permission.
What If My Boss Requires More Analysis Before Deciding?
When bosses require excessive analysis, present the 70% rule explicitly: “I have 70% of ideal information and 70% confidence. Additional analysis will delay decision by X days for Y% improvement. Recommend we proceed.” Make the tradeoff visible. Most leaders accept faster decisions when opportunity cost is quantified.
Does the 70% Rule Apply to Personal Decisions?
The 70% rule applies to personal decisions with similar logic: reversible choices with moderate stakes should be made quickly. Career changes, major purchases, and relationship decisions may warrant more deliberation, but even these suffer from excessive analysis. Act, learn, adjust.
