Jeff Bezos put a useful label on something most managers never stop to name. In his 2015 letter to Amazon shareholders, he split decisions into two kinds. Some are consequential and almost impossible to reverse, what he called one-way doors. You walk through, the door locks behind you, and living with the result is the only option left. Most decisions are nothing like that. They are two-way doors: you open them, step through, look around, and if you do not like what you find, you walk back and choose again. His warning was blunt. As organizations grow, they start running almost every decision through the slow, careful, one-way-door process, and the result is “slowness, unthoughtful risk aversion, failure to experiment sufficiently, and consequently diminished invention.”
I have watched capable managers do the individual version of this for twenty-five years. The problem is almost never that they decide badly. It is that they spend one-way-door effort on two-way-door choices, then wonder why the week disappeared and nothing actually shipped.
The test takes about ten seconds
Before you book a meeting or open a spreadsheet, ask one question about the decision in front of you: if this turns out to be wrong, how expensive is it to undo?
Running network operations at a large telecom early in my career, I sat on the choice of a new monitoring dashboard for the better part of a month. I built a comparison grid, pulled three vendors into demos, looped in two other teams for their opinions, and kept finding one more factor to weigh. It was a two-way door the whole time. If we had picked the wrong tool, the cost of switching was a weekend of reconfiguration and a mildly annoyed team. I treated a reversible choice like a marriage. The month I spent deliberating was worth more than any difference between the tools, and the delay itself had a cost: the gap in visibility I was trying to close stayed open the entire time I shopped.
Contrast that with a cutover I signed off on a year or two later, retiring a legacy billing dependency that half a dozen systems quietly relied on. That one was a one-way door. Once we pulled it, going back meant standing up decommissioned hardware under pressure in the middle of a business morning. It deserved every hour of the slow, methodical review we gave it, and more. The skill is not learning to decide faster in general. It is learning to tell the two apart, and then matching your effort to the door.
Most of what crosses a manager’s desk is a two-way door wearing a one-way costume. The standup time. The ticket queue structure. The pilot you could run with one team for three weeks. The agency you could try for a quarter. The vendor you could leave after the first contract term. Almost all of it is recoverable, and almost all of it gets treated as if the building depends on getting it perfect the first time.
Why steady, conscientious managers drift the wrong way
The drift toward the slow process is not laziness. It is the opposite. The managers who overbuild their decision-making tend to be the careful, responsible ones, and three forces pull them there.
The first is that reversing a decision feels like admitting the first one was a mistake, so people over-invest upfront to avoid ever having to walk back. The second is that nobody gets blamed for a decision that was studied to death, while a fast call that goes wrong looks reckless in hindsight, even when the fast call was correct given what was known. The third is simple contagion. Bezos was describing organizations for a reason: when the culture around you treats every choice as a committee event, matching that pace feels like diligence rather than waste.
The cost of all this is not abstract. McKinsey’s research on decision making found that executives spend an average of nearly 40 percent of their time making decisions, and that for a typical Fortune 500 company the ineffective part of that work burns roughly 530,000 days of managers’ time a year, about $250 million in wages. In a separate survey of more than 1,200 managers, 61 percent said that at least half the time they spend making decisions is used ineffectively. The same work found that the organizations which make decisions both quickly and well were about twice as likely to report strong returns from their recent choices. Speed and quality were not a tradeoff. The companies that classified correctly got both.
Sorting your week by door type
The practice is small enough to start this week, and it costs nothing.
Take whatever is sitting on you right now, the decisions you keep circling without closing, and label each one. One-way or two-way. Be honest about the undo cost rather than the anxiety the decision produces, because the two often have nothing to do with each other. A choice can feel enormous and still be a two-way door, and that feeling is exactly what keeps you deliberating long past the point of return.
For everything you label two-way, give yourself a deadline measured in hours, not weeks, and name the person who gets to make the call alone. That is usually you, sometimes someone one level down who is closer to the work and has been waiting for permission to just decide. Push these down and out. A two-way door is the safest possible training ground for a developing manager, because the cost of a wrong answer is a correction, not a catastrophe. Hoarding reversible decisions at your level is how you end up with a calendar full of judgment calls that drain you by noon while the genuinely consequential ones get the leftover attention.
For the one-way doors, slow down with a clear conscience. Convene the room. Run a premortem before you commit. Pull in the people who will have to live with the result. This is where careful, methodical process earns its keep, and where the hours you saved on the reversible pile should be spent instead.
The question that reorganizes a manager’s week is not “what is the right answer here.” It is “can I walk this back.” Ask it first, every time, and most of your decisions will turn out to be doors that swing both ways. Stop guarding them like they only open once.
