Use AI as a thinking partner to define problems, find causes, generate options, and decide well
Short answer
A free guide to using AI for problem-solving in 2026: defining the problem, root cause analysis, the five whys, breaking problems down, generating options, thinking models, pre-mortems, testing solutions, decision making, avoiding AI pitfalls, prompts, and a simple problem-solving routine.
AI is great at asking questions, seeing a problem from new angles, and generating options fast. It does not know your situation as well as you do, so the best results come from working with it step by step.
A problem well defined is half solved, and AI is great at helping you define it.
02
Define the problem
Help me define this problem clearly. Ask me up to seven questions, one at a time, about what is happening, since when, who is affected, and what success looks like. Then write a one-paragraph problem statement.
03
Find the root cause
Ask “why?” five times to dig below symptoms
List all possible causes, then rank them by evidence
Separate facts from assumptions
Ask AI which causes are most likely and how to test them
04
Break it into parts
Big problems feel impossible. Ask AI to split the problem into smaller parts you can solve one at a time, and to show which parts depend on others.
05
Generate options
Give me 15 different ways to solve this problem, from safe to bold. Include at least three unusual ideas. For each, give one benefit and one risk.
Quantity first, judgement later.
06
Use thinking models
First principles
Break it down to basic truths and rebuild
Inversion
Ask how to make the problem worse, then avoid that
Second-order thinking
Ask what happens after the first effect
Constraints
Ask what you would do with half the time or money
Ask AI to apply one model at a time to your problem.
07
Run a pre-mortem
Imagine we chose this solution and it failed badly six months from now. List the ten most likely reasons, and how we could prevent each one.
08
Decide
Compare the top options in a table: cost, time, risk, impact
Decide what matters most before scoring
Ask AI to argue against your favourite option
Make the decision yourself, and write down why
09
Test small
Turn the solution into a small experiment
Decide in advance what result counts as success
Review results and adjust
10
Avoid AI pitfalls
AI may sound confident when it is guessing
It can agree with you too easily, so ask it to challenge you
It lacks your full context, so give it facts, not just feelings
Check any facts it brings in
11
A simple routine
Define
What exactly is the problem?
Diagnose
Why is it happening?
Generate
What could we do?
Decide
What will we do, and why?
Test
How will we know it worked?
The golden rule
Do not ask AI for the answer. Ask it to help you think: define, diagnose, generate, decide, and test.
Define
Root cause
Options
Models
Pre-mortem
Decide
Test
Pick one problem you are stuck on and run it through the five steps with AI today.
