Opportunity Solution Trees

Teresa Torres' map from a single outcome at the root, through the user opportunities that could move it, down to solutions and the experiments that test them. Discovery with a structure.

A WHAT IT IS

The framework

The Opportunity Solution Tree (OST), from Teresa Torres' Continuous Discovery Habits, is a visual framework that organises an entire discovery programme: a single desired outcome at the root, a structured hierarchy of user opportunities beneath it, solutions for each opportunity, and experiments that test those solutions.

The tree keeps discovery anchored to an outcome instead of wandering into interesting-but-irrelevant research. Its discipline is that every solution must trace up to a real user opportunity, which must trace up to the business outcome — so you can't fall in love with a solution that serves no opportunity. It also makes the solution space visible: by forcing multiple opportunities and multiple solutions per opportunity, it fights the instinct to commit to the first idea.

THE TREE STRUCTURE

Outcome (root) — the one business/product result you're driving
Opportunities — user needs, pains, desires that could move the outcome
Solutions — ways to address each opportunity (at least 3)
Experiments — tests that validate each solution

B WHY IT MATTERS

What it prevents

Unstructured discovery wanders — lots of interesting research, no clear line from insight to a decision that moves the outcome.

The shortcutWhat it costsWhat it gives you instead
Discovery with no anchorResearch drifts; findings don't connect to any outcome.The outcome at the root keeps everything pointed at one result.
Falling for the first solutionThe team commits to one idea before exploring the space.Requiring multiple opportunities and solutions keeps options open.
Solutions with no opportunityBuilding something that serves no real user need.Every solution must trace up to a validated opportunity.
No link from research to decisionInsights pile up but never resolve into a choice.The tree turns opportunities into prioritised, testable solutions.
C HOW TO RUN IT

Step by step

1

Start with one desired outcome

Put a single, measurable business or product outcome at the root — the thing all this discovery is meant to move. Not an output, an outcome.

2

Map the opportunity space

Branch the outcome into the user opportunities — needs, pains, desires — that could move it, drawn from research. Aim for breadth before depth; the goal is to see the whole space.

3

Generate at least three solutions per opportunity

For the priority opportunities, force multiple solution ideas. The minimum-three rule defeats the instinct to commit to the first idea and reveals better options.

4

Prioritise opportunities, then solutions

You can't pursue every branch. Choose the opportunity most likely to move the outcome, then the most promising solutions within it.

5

Design experiments to test the top solutions

For the highest-priority solutions, design experiments that test their riskiest assumption. The tree's leaves are tests, not commitments — evidence decides what gets built.

D IN PRACTICE

A short illustration

IN PRACTICEstructured discovery

A team did plenty of research but it sprawled — interviews, ideas, and pet features with no clear connection to any goal. Decisions came down to whoever argued best, because nothing linked the research to the outcome.

Building an OST forced the structure: one outcome at the root, the opportunities that could actually move it mapped beneath, and — crucially — at least three solutions per opportunity instead of the one everyone had fixated on. Two of those alternative solutions turned out stronger than the original favourite, and every choice could now be traced from experiment up to outcome.

The lesson: structure doesn't constrain discovery — it focuses it. The tree's two best habits are anchoring everything to one outcome and forcing multiple solutions per opportunity, which together kill both wandering and premature commitment.
E THE ARTIFACT

The opportunity solution tree

The deliverable is the visual tree itself — outcome, opportunities, solutions, experiments — maintained as a living map of the discovery programme.

F THE SO-WHAT

Why it matters

THE KEY INSIGHT

The tree's job is to make discovery traceable: every experiment connects up through a solution and an opportunity to the one outcome you're driving. Anything that can't be traced doesn't belong.

Two of the tree's rules do most of the work. Anchoring to a single outcome stops discovery from sprawling into interesting irrelevance. And forcing at least three solutions per opportunity breaks the most common discovery failure — falling in love with the first idea before the space has been explored. Together they turn discovery from a pile of research into a structured argument: here's the outcome, here are the opportunities that move it, here are the solutions we compared, and here's the evidence for the one we chose.

G MISTAKES & LIMITS

Common mistakes

Multiple outcomes at the root

More than one outcome and the tree loses focus. Pick the single result you're driving.

One solution per opportunity

Skipping the minimum-three rule reintroduces premature commitment. Force alternatives.

Inventing opportunities

Opportunities must come from real research, not the team's imagination.

Treating it as static

The tree is a living map — update it as research and experiments teach you.

When not to use it

H CONNECTS TO

Where this sits in the toolkit

Anchors → the Discovery loop

The OST is how the discovery loop (Tool 02) stays organised around an outcome instead of wandering.

Fed by → Problem Framing & research

Opportunities come from problem framing (Tool 04) and the qualitative/quantitative research tools.

Leads to → the experiment tools

The tree's experiment leaves are run with lean experiments, fake doors, and prototypes (Tools 15–19).

Prioritised with → Module 1 frameworks

Choosing which opportunities and solutions to pursue uses RICE/ICE-style prioritisation.

TRY IT YOURSELF

Sketch a tree for an outcome you care about

Pick one measurable outcome. Branch it into two or three user opportunities that could move it. For one opportunity, force yourself to write three different solutions.

Notice whether your favourite solution still looks best once you've generated two alternatives beside it.

If one of the alternative solutions you were forced to invent turns out stronger than your original idea, the minimum-three rule has just done its job — that's why it exists.
