Decision-making frameworks for leaders: how to decide faster and better
Good leaders decide at the right speed and make it clear who decides. Use one-way and two-way doors to set the speed, RAPID or DACI to set roles, OODA for fast-moving situations, Cynefin to choose between planning and experimenting, a pre-mortem to spot risks, and 10/10/10 to keep short-term emotion in perspective.
- Match decision speed to how reversible the decision is
- Make one person clearly accountable for each decision
- In uncertain situations, run small experiments instead of big plans
- Run a pre-mortem before big commitments
- Write down the decision and the reasoning
Most teams don't suffer from bad decisions as much as from slow or unclear ones: nobody knows who decides, meetings end without a call, and reversible choices get treated like bet-the-company moves. These frameworks fix that.
1. One-way and two-way doors: set the speed
Jeff Bezos described two kinds of decisions in his 2015 letter to Amazon shareholders:
- One-way doors are hard or impossible to reverse: a large acquisition, shutting a business line, a senior hire. Decide carefully and consult widely.
- Two-way doors can be reversed: a pricing test, a new process, a campaign. Decide quickly, with a small group, and learn from the result.
Most decisions are two-way doors. Treating them as one-way doors is how organisations slow down.
2. RAPID: who does what in a decision
Developed by Bain & Company, RAPID names the roles:
- Recommend: gathers input and proposes a decision.
- Agree: must sign off (use sparingly, for example legal or compliance).
- Perform: carries out the decision.
- Input: consulted for facts and views.
- Decide: makes the final call. One person.
3. DACI: a simpler version for projects
- Driver: runs the process and gets the decision made.
- Approver: makes the decision (one person).
- Contributors: provide expertise.
- Informed: told the outcome.
Write the DACI at the top of any decision document. It ends the "who's deciding this?" debate.
4. The OODA loop: decide in fast-moving situations
John Boyd's loop: Observe what's happening, Orient (make sense of it), Decide, Act, and repeat. The team that loops faster than its competitor or the crisis wins. Use it during a launch, an outage or a market shock.
5. Cynefin: choose the right approach
Dave Snowden's Cynefin framework sorts situations into domains:
| Situation | What it looks like | What to do |
|---|---|---|
| Clear | Cause and effect are obvious | Apply best practice |
| Complicated | Experts can work out the answer | Analyse, then act |
| Complex | Cause and effect are only clear in hindsight | Run small experiments, amplify what works |
| Chaotic | No clear cause and effect, urgent | Act to stabilise, then reassess |
A common mistake is treating a complex problem (entering a new market) as complicated (one big analysis and plan).
6. The pre-mortem: find risks before they happen
Psychologist Gary Klein's technique: before committing, imagine it's a year later and the decision has failed. Each person writes down why. You surface risks that people would otherwise keep to themselves.
7. 10/10/10: keep emotion in proportion
From writer Suzy Welch: how will I feel about this decision in 10 minutes, 10 months and 10 years? Useful for hard people decisions and career moves.
A simple decision process
- Is it a one-way or two-way door?
- Who decides (DACI or RAPID)?
- What kind of situation is it (Cynefin)?
- For big decisions, run a pre-mortem.
- Decide, write down the reasoning, and set a date to review.
Frequently asked questions
What is the best decision-making framework for managers?
For everyday use, combine one-way and two-way doors (to set the speed) with DACI or RAPID (to make roles clear). Add Cynefin and pre-mortems for larger, uncertain decisions.
What's the difference between RAPID and DACI?
Both clarify roles in a decision. RAPID, from Bain, adds an "Agree" role for mandatory sign-offs and separates who performs the decision. DACI is simpler and common for project decisions.
How do I make decisions faster as a leader?
Treat reversible decisions as two-way doors, give one person the authority to decide, set a deadline, and accept that some decisions will be corrected later.
How do I talk about decision-making in an interview?
Use a STAR story: the situation, the decision you owned, the framework or process you used, and the measurable result.
