Most senior leaders pride themselves on being decisive. What they rarely examine is whether they are decisive about the right things, at the right speed, with the right amount of deliberation.

​

The reversible/irreversible decision test is the simplest and most effective framework for fixing that. It takes thirty seconds to apply and changes the quality of every decision that follows.

​

The Core principle

​

The speed at which you should make a decision is determined by one thing: how expensive it is to be wrong.

​

That sounds obvious. In practice, most leaders treat all decisions as roughly equivalent - running the same meeting process, the same approval layers, the same gut-check sequence regardless of the actual stakes involved. That is where the mistake happens.

​

Some decisions can be undone. Others cannot. Treating them the same way guaranteed you will move too slowly on the things that need speed and too quickly on the things that need care.

​

01  Ask: is the decision reversible?

Before any significant decision, ask one question: if this turns out to be wrong, can we undo it?

​

A reversible decision is one where the cost of being wrong is manageable. you can course-correct. You can change direction. The mistake doesn't compound.

​

Examples of reversible decisions:

​

 - Testing a new pricing structure with a segment of clients

 - Hiring a contractor for a defined project

 - Changing your content or marketing strategy

 - Trialling a new supplier or service provider

 - Moving to a new project management tool

​

These decisions deserve speed. The right instinct is to move, gather real data, and correct course quickly if needed. Overthinking a reversible decision is itself a cost, it consumes management time and delays learning that only comes from doing.

​

​

02 If irreversible, slow down deliberately

An irreversible decision is one where the cost of being wrong is high and the ability to undo it is limited.

​

Examples of irreversible decision:

 - Signing a co-founder or shareholder agreement

 - Making a major capital commitment - debt, equity, or infrastructure

 - A key hire into a senior or equity-bearing role

 - A significant market pivot or brand repositioning

 - Exiting a business line, geography, or a long-term contract.

​

These decisions deserve the opposite of speed. More information. More challenge. More time for the picture to clarify. The cost of being wrong is high. The cost of being slower is low in comparison.

​

This is not an argument for indecision. It is an argument for proportionate deliberation, matching the depth of your process to the actual stakes involved.

​

03 Name the decision type before you make it

​

This is the step most leaders skip, and it is the one that makes the framework work in practice.

​

Before any significant decision, say out loud - in the meeting, in teh conversation, in your own thinking:

​

​

​

​

It sounds simple. It changes the quality of everything that follows.

​

When a names a decision as reversible, the meeting shifts. The conversation moves faster. People stop seeking consensus on things that don't require it. Someone makes the call. You move.

​

When a team names a decision as irreversible, the meeting shifts differently. People slow down. They are harder questions. They look for the information they don't yet have. They challenge assumptions they might otherwise let pass.

​

The label does the work. You don't need a lengthy process audit. you need one honest answer before the conversation starts.

​

04 Watch for manufactured urgency on irreversible decisions

 

This is where the framework earns its keep.

​

The most dangerous version of a bad decision is an irreversible one made under artificial pressure. It happens more often than most leaders admit and it is almost always someone else who creates the urgency.

​

​

​

​

These phrases appear constantly in capital raises, acquisitions, senior hires, and major contracts. Sometimes the deadline is real. Often it is a pressure tactic, a mechanism to prevent you from gathering the information that would change your answer.

​

The correct response to a deadline on an irreversible decision is always the same: ask what changes after Friday. Push on the answer. Be genuinely sceptical of the urgency until you understand its source.

​

A counterparty who cannot explain why the deadline exists, or whose explanation doesn't hold up, is telling you something important about how they will beave once the deal is signed.

​

 

The Bottom Line

​

Most decision-making frameworks ask you to gather more information, consult more stakeholders, or build more elaborate models. This one asks you to do something simpler first: decide what kind of decision you are making.

​

Reversible? Move fast. Gather data from the doing.

Irreversible? Slow down deliberately. The cost of being wrong is too high to rush.

​

One honest answer to that question before the conversation starts is worth more than any process that follows it.
