How to make decisions under uncertainty: 5 approaches for managers

Every manager eventually finds themselves in a situation where action is required, but the data is incomplete, forecasts conflict with one another, and every option seems risky. Markets change, regulations are updated, and the team is waiting for an answer. At such moments, it becomes clear that decision-making under uncertainty is a specific skill. And like any skill, it can be developed.

Why uncertainty is paralyzing – and what to do about it

The human brain is evolutionarily wired to avoid the unknown because it perceives uncertainty as a threat. As a result, managers facing a lack of information often either postpone decisions until the last possible moment or make impulsive choices simply to relieve the tension. Both approaches frequently lead to worse outcomes than making a well-considered decision based on incomplete information.

Fortunately, there are proven methods that help leaders act confidently even when they do not have the full picture. Let’s look at five approaches that genuinely work in business management practice.

Approach 1. Separate risks: what is reversible and what is not

The first question you should ask yourself before making any difficult decision is: How reversible is this decision?

Jeff Bezos referred to this concept as the distinction between “one-way doors” and “two-way doors.” Two-way-door decisions can be reversed or adjusted. They can be made quickly, even with limited information. One-way-door decisions are difficult or impossible to reverse: changing strategy, making major investments, or hiring for a key position. These require thorough analysis.

Many managers spend the same amount of time on both types of decisions – and that is a mistake. Categorize decisions based on reversibility. This immediately reduces anxiety and increases speed where speed matters most.

Approach 2. The pre-mortem method: think about failure in advance

One of the most effective tools in management practice is the pre-mortem method, developed by psychologist Gary Klein. The idea is simple: before making a decision, imagine that a year has passed and your plan has failed. Ask yourself and your team: What exactly went wrong?

This technique works because it eliminates groupthink – the tendency for people to agree out of politeness or deference to authority. When you allow the team to treat failure as an established fact, people begin to voice risks they might otherwise keep to themselves.

How to apply it in practice:

  • Set aside 20–30 minutes before making the final decision.
  • Ask each participant to write down 2–3 reasons why the plan might fail.
  • Collect the responses, group the risks, and assess which ones are genuinely critical.

Approach 3. The principle of a “good enough” decision

In uncertain conditions, searching for the perfect decision is often a luxury that businesses cannot afford. Economist Herbert Simon introduced the concept of satisficing (a combination of satisfy and suffice): making a decision that is good enough – not necessarily optimal, but one that meets the key requirements.

In practice, this means defining a minimum set of criteria in advance. For example: “We need a contractor who fits our budget, has experience in our industry, and can start within two weeks.” The first candidate who meets all three criteria becomes your choice. Do not continue searching for someone better.

This approach is especially important in situations where the cost of delay exceeds the cost of an imperfect decision.

Approach 4. The OODA loop: act, observe, adjust

The OODA methodology (Observe – Orient – Decide – Act) was developed by military strategist John Boyd and is now widely used in business. The principle is not to predict everything in advance, but to move forward through short iterations: observe the situation, orient yourself within it, make a decision, take action, and immediately begin the cycle again.

For small and medium-sized businesses, this means you do not need to wait until you fully understand a situation before taking action. Start with a small step, observe the response, and adjust your course as you move forward. Launching a new product, entering a new customer segment, or changing a pricing strategy are all initiatives that are better tested on a limited scale than planned in isolation for years.

By the way, when operating under uncertainty, financial transparency becomes your most important reference point. If you know the exact state of your cash flow, the profitability of each business area, and your actual tax burden, you can make decisions based on facts rather than intuition.

Approach 5. The Eisenhower Matrix: prioritize before choosing

Sometimes the challenge is not how to make a decision, but which decision should be made first. An overloaded manager may be trying to put out several fires at once and ends up focusing effectively on none of them.

The Eisenhower Matrix divides all tasks and decisions into four categories:
Urgent
Not urgent
Important
Do immediately
Schedule
Not important
Delegate
Eliminate
In uncertain conditions, many managers get stuck in the “urgent but not important” quadrant – reacting to noise instead of focusing on real priorities. The solution is to regularly, at least once a week, write down all current tasks and sort them using the matrix. This takes only 15 minutes but can dramatically improve the quality of managerial decision-making.

How to combine all five approaches into a system

Each of these tools works well on its own. Together, they are even more powerful. Here is how you can integrate them into your management practice:

  1. Before every difficult decision, determine whether it is reversible or irreversible (Approach 1).
  2. When working with your team, use a pre-mortem to uncover hidden risks (Approach 2).
  3. When there is no time for lengthy analysis, apply the satisficing principle and define your criteria in advance (Approach 3).
  4. For new initiatives and hypotheses, move forward through OODA-based iterations (Approach 4).
  5. When everything seems equally important, prioritize using the Eisenhower Matrix (Approach 5).

It is important to remember that many managerial decisions that appear strategic are actually driven by financial data. Should you launch a new business line? Hire a new employee or outsource the work? Enter a new market? You can answer these questions under uncertainty only if you have up-to-date management reporting and a clear understanding of the company’s real financial position. Without that foundation, any decision-making methodology loses much of its effectiveness.

The key takeaway: uncertainty is a condition, not an obstacle

The most common mistake is waiting for the moment when “everything becomes clear.” For most management decisions, that moment will never come. Uncertainty is not a temporary stage before stability – it is the permanent environment in which modern businesses operate.

Managers who succeed in such an environment do not possess a special gift for predicting the future. They have simply mastered a set of effective methods and apply them consistently, without waiting for perfect conditions.
