Decision Making in Business: A Guide for Leaders Who Decide All Day

Most of the decisions that shape a company are made on an ordinary afternoon, between two other meetings, by someone who is slightly tired. Decision making in business mostly happens in small moments: a yes sent from a phone, a hire approved because the role has been open too long, a price left alone because changing it felt risky.

In short: good business decisions come less from being clever and more from a short routine you run every time. Sort the decision by how hard it is to undo. Frame it with real alternatives. Look past the first consequence. Imagine it failing before it does. Decide in a decent state, on a deadline. Write it down so you can learn from it.

That is the whole method. The rest of this guide takes each step in turn and points to the longer piece on it, so you can go as deep as the decision in front of you deserves.

Why Process Beats Being Smart

Most leaders believe their decisions are limited by the quality of their analysis. More data, a sharper model, one more week. The largest study of real business decisions suggests they are looking in the wrong place.

Dan Lovallo and Olivier Sibony studied 1,048 major decisions, covering investments, acquisitions and capital spending, and compared how each one was analysed with how it was decided. Process explained about 39 percent of the difference in outcomes. Analysis explained about 8 percent. Their write-up in McKinsey Quarterly is worth reading in full.

By process they meant unglamorous things. Exploring alternatives to the proposal on the table. Checking whether the numbers were built to answer the question or to support an answer already chosen. Agreeing in advance what would count as evidence against. Naming who decides, and when.

There is a second reason to trust a routine over your instincts, and it is harder to feel. In a study described in the book Noise, insurance executives guessed that two of their own underwriters would price the same risk about 10 percent apart. The measured gap was 55 percent. Same firm, same training, same file. Each underwriter felt reasonable, and each was. The variation was invisible from the inside.

That is the case for structured decision making in one finding. Judgement is not the enemy. Unchecked judgement is simply noisier than anyone running it can tell.

Step One: Sort the Decision Before You Make It

The first question is how hard the decision is to undo, because the answer sets how much effort everything else deserves.

Jeff Bezos split decisions into two types in his letters to Amazon shareholders. Some are one-way doors: walk through, dislike what you find, and you cannot get back. Most are two-way doors, and those can be made quickly with a light process. “Many decisions are reversible, two-way doors,” he wrote in his 2016 letter. His warning was that growing companies start applying the heavy process to everything.

Most organisations run this backwards. They spend weeks on reversible choices because those come up often and feel visible, then rush the irreversible ones because a deadline appeared. The piece on rapid decision making covers the fast side: when speed beats accuracy, and how to put a clock on a choice that keeps coming back to your inbox.

The hard side is spotting the one-way doors that are dressed as two-way ones. A first senior hire looks reversible until you count what it costs to unwind. So does a discount you give your biggest customer. Reversibility comes down to what undoing it would cost, which is the argument in Alex Hormozi’s decision framework, applied backwards.

The same sort works outside the office. Whether to pay for help with a retirement account, the subject of our piece on whether you need a financial advisor for your 401k, is mostly reversible if you watch the fees. A career change at 40 sits much closer to a one-way door, which is why it deserves a test run before the resignation letter.

Step Two: Frame It With Real Alternatives

The most common mistake in a real decision happens before any judgement is made. It is the frame.

“Should we hire this person or not?” is a question with one option in it, dressed up as two. Research by the management scholar Paul Nutt, which Chip and Dan Heath build on in Decisive, found that “whether or not” decisions failed far more often than decisions where people compared two or more genuine alternatives.

The fix takes ten minutes. Before deciding, write down at least one real option that is not “do nothing”. Then write your criteria, what a good outcome looks like, before you look closely at the options. Criteria written afterwards tend to describe whichever option you already liked.

Our decision making framework you will actually use turns this into five questions that fit on a single page. It is built for a founder choosing between two suppliers on a Wednesday afternoon.

Step Three: Look Past the First Consequence

Most bad business decisions were sensible at the moment they were made. They worked at the first step and went wrong at the third.

Cut prices to win share and you win share. Then your strongest competitor matches you within a month, the whole category resets lower, and everyone earns less for the same work. The first step did exactly what it was meant to do.

Hire a salesperson to grow revenue and revenue grows. What the plan missed is that the new hire sells whatever is easiest to sell, the founder now spends hours a week managing instead of building, and discounted customers leave faster. None of it shows up in month one. All of it shows up by month nine.

Second order thinking is the habit of asking one more question: and then what? The first consequence arrives with evidence attached. The later ones arrive quietly and get blamed on something else.

Step Four: Imagine It Failing First

Once a decision is nearly made, the people around it stop looking for problems. Nobody wants to be the one slowing things down.

The psychologist Gary Klein designed the premortem to get around that. Before committing, the team imagines it is a year later and the decision has failed badly. Each person writes down why. Klein described the method in the Harvard Business Review, and its strength is that it makes raising a doubt the assignment rather than an act of disloyalty.

It costs about twenty minutes. For a one-way door, there is no cheaper insurance.

Step Five: Decide in the Right State

Late in a hard day, people decide worse. You have felt it: the third time a question comes up, you reach for whichever answer ends the conversation fastest.

The popular explanation, that willpower drains like a battery, rests on research that is far shakier than the advice built on top of it. The famous parole board study is one of the most contested results in behavioural science. The piece on decision fatigue goes through what the evidence does and does not show, and why that changes the remedy.

The practical rule that survives is simple. Decide the rule when you are fresh, and apply it to the case when you are tired. Pricing rules, hiring bars and spending limits should be set on a clear morning, so that the evening version of you only has to follow them.

Give every open decision a deadline as well. A choice without a date tends to get heavier every time you look away from it.

Step Six: Write It Down and Check It Later

Most people learn the wrong lesson from their decisions. A good call that turned out badly gets treated as a mistake. A reckless call that got lucky gets repeated.

The defence is a short written record made at the time: what you decided, what you expected to happen, and why. Add a date to check back. When the date comes, you compare the outcome to the reasoning, and you can finally tell bad luck from bad judgement.

Annie Duke builds a whole book around that distinction in Thinking in Bets. It is second on our list of the best books for decision making, which is ranked by a narrow test: what each book changes about the next decision you make.

Executive Decision Making Is Mostly the Decisions You Never See

Everything above applies to the decisions a leader makes personally. Executive decision making has a second half, and in a growing company it soon becomes the larger one: the hundreds of decisions made every week by people the executive never speaks to.

Those decisions are only as good as the direction they are given. A useful vision is a decision tool. It lets two competent people settle an argument without escalating it, in the direction the leader would have chosen. A vision everyone agrees with cannot do that, which is the argument in the CEO’s guide to crafting a vision that actually works.

This is also where the difference between leadership vs management becomes practical. Management builds the routine that lets decisions get made well. Leadership decides where those decisions are meant to point.

Decision Making in Business, on One Page

The whole method fits in a table. Print it, or keep it next to whatever you decide on most often.

Step	The question	Time it takes
1. Sort	How expensive is this to undo?	Two minutes
2. Frame	What is the real alternative, and what does good look like?	Ten minutes
3. Look ahead	If this works, what happens next, and after that?	Ten minutes
4. Premortem	It failed a year from now. Why?	Twenty minutes, one-way doors only
5. Timing	Am I deciding the rule or the case, and when is the deadline?	One minute
6. Record	What did I expect, and when will I check?	Five minutes

For a two-way door, steps one, two and five are enough, and the whole thing takes a quarter of an hour. For a one-way door, run all six. Either way, the routine costs less than a week of circling the same question.

The Routine Is the Advantage

Nobody makes every call well. The leaders who decide well over years are mostly the ones who made the same few checks every time, including on the days they did not feel like it.

That is the quiet finding under all of this. Decision making in business is a habit more than a talent, and a habit can be copied. Pick the decision that has been sitting on your desk the longest, and run it through the table today.
