How to Overcome Decision Fatigue

At Hospira, a $3.6 billion medical-device and pharmaceutical manufacturer, approving a marketing brochure required handwritten changes on paper copies circulated in manila folders. Bain profiled the company as part of a ten-year study across nearly 800 companies. Eighty percent of people surveyed said their decisions consumed excessive effort. The company scored at the 40th percentile on decision effectiveness. Nobody at Hospira needed lifestyle advice on how to overcome decision fatigue. The process itself was the problem.

Every article on how to overcome decision fatigue tells you to sleep more and simplify your wardrobe. I have spent more than forty years working with organisations that cannot close on decisions, and in every case the fatigue came from the process between the Decider and the decision, not from the Decider's energy levels. Decision fatigue in organisations is not a depleted mental battery. It is the accumulated weight of a governance apparatus that produces everything except sufficient certainty that the decision will deliver the intended outcome.

The standard advice treats the wrong problem

The causes are not mysterious. A 2025 review across 23 peer-reviewed studies found ten. Six are organisational: complexity of the decision-making process, weight of responsibilities, high workload, weak organisational culture, duration effects, and availability of breaks. Three are individual. One is external. The standard tips address only the three individual causes. The six require structural changes. No amount of sleep will fix them. The people selling morning routines and willpower hacks address those three and ignore the six.

McKinsey found the same diagnosis from a different angle. Seventy-two percent of senior executives surveyed said bad strategic decisions were as frequent as good ones or were the prevailing norm. One specialty-chemicals company they profiled had six governance committees, every senior leader a member of every committee, no designated Decider for any of them. I have seen this arrangement in every sector I have worked in. Leaders described "death by committee." The fatigue was not produced by too many personal choices. It was produced by an apparatus that converted every question into a meeting that nobody owned.

Five steps to overcome decision fatigue at the source

The fix is not a lifestyle adjustment. It is replacing the apparatus entirely. The Universal Decision-Making Method that Roger Estall and I built replaces the governance apparatus with five steps. Any Decider can apply them to any decision, in any context, without committees, risk registers, or appetite statements.

First, frame the decision. State the organisation's Purpose, the opportunity, the desired outcome, the intended duration, and the Context. Most governance processes skip this entirely, and the result is predictable: six committees, not one of them with a written statement of the question it was answering.

Second, develop options. Identify the primary elements of the decision, the substance of what you will do, and the secondary elements, the conditions and safeguards you attach to make the outcome more certain.

Third, recognise assumptions. Every decision rests on a mix of facts and predictions, but most processes treat predictions as though they were facts. This is the step most processes miss, and it is where the fatigue dissolves.

Fourth, test for sufficient certainty. Not maximum certainty. The difference is what stops the treadmill.

Fifth, design monitoring. Decide in advance what conditions would tell you the decision is working and what would cause you to revisit. This replaces the open-ended register that gets reviewed quarterly with information nobody acts on.

Surface what the decision actually rests on

The third step is where executive decision fatigue breaks. I have watched boards spend six months circling a decision with 47-item risk registers, heat maps, and risk matrices, none of which stated what the decision actually rested on. One question cuts through the entire apparatus: "What are the assumptions we are making here?"

Consider a pricing decision. The Decider has production costs and distribution costs. These look like facts. But the pricing also rests on predictions about unit volume, and those predictions assume a competitor will not undercut within six months. That assumption is the one the decision depends on. A risk register would list dozens of items and never isolate it. The method isolates it because it asks which assumptions carry the most influence on the desired outcome and where confidence is lowest.

In Deciding, Roger Estall and I described a significance matrix that sorts assumptions by two factors: how much the outcome depends on each one, and how confident you are in it. A 47-item register compresses to the three or four assumptions that actually drive the decision. The rest falls away.

When I have done this with boards, the conversation changes immediately. The months of circling stop because the room is no longer debating abstractions. They are looking at specific statements about the world, each with a confidence level attached, each with a clear path to resolution. Once assumptions are visible, the Decider can act on them directly: obtain information or add safeguards that increase confidence, or choose a different path with fewer critical assumptions.

Sufficient certainty stops the decision fatigue treadmill

The governance apparatus creates fatigue because it never produces a stopping point. There is always another report, another register update, another committee review. The pursuit of maximum certainty is itself the treadmill. Sufficient certainty is the point at which the Decider has enough confidence that the desired outcome will be achieved, given the cost and effort of achieving more.

Roger Estall described the shift that quality management made in the 1980s: from inspecting the final product and throwing out the duds to fixing the process, because dud products are the outcome of dud processes. The same principle applies here. Stop inspecting the Decider's energy levels and sleep patterns. The dud decisions are coming off the line because the line is broken.

Hospira made this shift. After clarifying decision roles and stripping out approval layers, its stock price rose more than 80 percent, total shareholder returns reached the upper quartile, and cost and revenue targets were exceeded. Bain's wider study confirmed the pattern: companies in the top quintile for decision effectiveness were eight times more likely to execute well, with total shareholder returns nearly six percentage points higher. Decision fatigue is real. The question of how to overcome decision fatigue was never about the person. It was always about the process.
