Decision fatigue in B2B commercial leadership
Examine decision load, priorities and habits when commercial leadership becomes more demanding.
By 3pm on most days, the average executive has already made hundreds of decisions. What to prioritise. What to ignore. What to say in that message. Whether to reschedule. Who needs a response.
Most of these decisions are small. But they add up. And they cost something.
Decision fatigue is the gradual deterioration of decision quality as the day progresses. It's well-documented in the research and wildly underestimated by most leaders I work with.
What it looks like in practice
It doesn't feel like tiredness. It feels like everything taking slightly longer to decide. More second-guessing. More decisions deferred. More impulse choices at the end of the day that you wouldn't make in the morning.
Decisions about strategy, people and culture often come when you have the least energy to think them through.
Why it matters more now than ever
The complexity and pace of modern leadership have raised the volume of decisions dramatically. Constant connectivity means there's rarely a natural reset. You're making decisions across more contexts, more stakeholders, and more time zones than any previous generation of leaders.
The leaders who handle this well aren't smarter. They're more deliberate about how they structure their day and protect their cognitive capacity.
Four practical ways to reduce decision fatigue
First: make fewer decisions. This sounds obvious but it's underused. Delegate more. Set default answers for recurring situations. Build routines that eliminate the need to decide the same things repeatedly.
Second: put your most important decisions in the morning, when your decision-making quality is highest. Don't start the day with your inbox.
Third: separate information-gathering from decision-making. Trying to do both at once increases cognitive load. Gather first. Decide separately.
Fourth: build in deliberate recovery during the day. Even a 10-minute walk without your phone allows the prefrontal cortex to reset. This isn't downtime, it's part of your performance system.
The bigger principle
Your brain is not a machine that degrades evenly. It has peaks and troughs, and learning to work with that rhythm instead of against it is one of the highest-leverage things a leader can do.
The goal isn't to make more decisions faster. It's to protect the quality of the ones that matter most.
