Compare Downside and Upside Against Your Business’s Capacity
Maximin and maximax are criteria for deciding what to prioritize under uncertainty. Use them to distinguish which outcomes matter, rather than treating them as personality types.
Are you protecting against the worst result or pursuing the best? Making that distinction explicit improves discussion. Choose the approach that fits your resources, market, and the consequences of failure, instead of debating which principle is universally right.
Why Decisions Become Inconsistent
Uncertainty can make yesterday’s confidence turn into today’s caution.
Unclear criteria can matter as much as missing information. Without an agreed priority, emotions and surrounding opinions pull decisions in different directions. Conclusions change from meeting to meeting and leave the organization uncertain.
Give intuition a foundation. Maximin and maximax offer two ways to establish one.
How the Two Principles Differ
Both apply to uncertain outcomes, but they focus on different results.
Maximin examines each option’s worst outcome and selects the best among those worst outcomes. It emphasizes the seriousness of failure.
Maximax examines each option’s best outcome and selects the greatest of those. It emphasizes the scale of success.
| Aspect | Maximin | Maximax |
|---|---|---|
| Outcome considered | Worst | Best |
| Priority | Avoiding loss | Maximizing gains |
| Suitable situation | Failure would be unacceptable | A substantial growth opportunity exists |
| Orientation | Protective | Growth-seeking |
The distinction concerns what to protect and what to pursue, beyond a simple ranking of the principles.
A Numerical Example
Suppose there are three new-business proposals, and you cannot predict whether the market will be strong or weak.
- Business A earns 10 in a strong market and loses 5 in a weak one
- Business B earns 3 in a strong market and earns 1 in a weak one
- Business C earns 6 in a strong market and loses 2 in a weak one
Maximin compares the worst results: A is minus 5, B is plus 1, and C is minus 2. B has the best worst-case result, so it is selected.
Maximax compares the best results: A is plus 10, B is plus 3, and C is plus 6. A has the highest upside, so it is selected.
The same information produces different choices under different criteria. When a meeting divides, clarify which criterion each person is using.
Four Factors for Choosing a Criterion
Explicit factors create consistency instead of leaving the choice to mood.
1. Severity of Failure
Assess the worst case first. If failure could threaten the company’s survival, protection deserves priority.
Tight cash flow, difficult-to-repair loss of trust, or potentially fatal customer departures strengthen the case for maximin. Avoiding irreparable harm comes before pursuing a large gain.
See using premortem analysis to identify risks for imagining a failed future and identifying overlooked concerns before deciding.
2. Business Resilience
The same loss can be manageable for one company and overwhelming for another.
Available cash, a stable existing business, and the ability to recover create room to consider a maximax approach. Greater resilience expands the available choices.
3. Market Opportunity
Pure caution can miss opportunities in a rapidly growing market. Conversely, aggressive expansion in a mature or shrinking market can be damaging.
Early action in a growing market may offer substantial rewards. Consider the market environment alongside the principle itself.
4. Time Horizon
Short-term stability and long-term expansion can call for different criteria.
Maximin may fit protecting the current period’s performance. Maximax may fit building a growth base several years ahead. The appropriate judgment changes with the horizon.

Frequently Asked Questions
Q: Is maximin excessively pessimistic?
A: It focuses on the severity of failure. When the worst result would be fatal, that can be a rational priority.
Q: Is maximax reckless?
A: Not necessarily. A resilient business with a substantial market opportunity may have a reason to pursue the highest upside.
Q: Is there an approach between them?
A: Yes. Other approaches weigh both the best and worst outcomes. Understanding these two first helps reveal your own emphasis.
Q: How can I organize disagreement in a meeting?
A: Separate views emphasizing the worst outcome from those emphasizing the best. This makes the issue explicit and reduces emotionally driven discussion.
Q: Can I use these ideas in everyday decisions?
A: Yes. Career moves, investments, and education choices also involve uncertainty. The distinction clarifies what you want to avoid and what you want to pursue.
