Product Ideation Framework

A repeatable path from insight to a shortlist worth building

Design-thinking ideation gives you the creative rules. A product ideation framework gives you the funnel: how a validated insight becomes a How Might We question, becomes a wide set of ideas, becomes a small set of concepts worth testing.

Step-by-step lessons

From Insight to Shortlist

Four short lessons: the ideation funnel, writing How Might We questions, generating ideas at product scale, and evaluating what you generate.

1

The Ideation Funnel

Product ideation works best as a funnel: it starts wide with evidence and narrows step by step toward something you can actually build and test.

1

Insight

A validated finding from research — the raw material everything else is built from.

2

How Might We question

The insight reframed as an open, optimistic prompt.

3

Ideas

A wide set generated from the HMW question — quantity over quality here.

4

Concepts

The strongest few ideas, fleshed out enough to evaluate properly.

5

Shortlist

Concepts ranked and ready for prototyping.

Writing How Might We Questions

A How Might We (HMW) question reframes an insight as an open, solution-neutral prompt. Scope it carefully: too broad and it produces noise; too narrow and it's already a solution in disguise.

Too broad

"How might we improve retention?"

Could point anywhere. Loses the specific insight it should be built from.

Well-scoped

"How might we help new sellers price with confidence?"

Grounded in a specific insight, open enough for many possible answers.

Too narrow

"How might we add a price-suggestion tooltip?"

Already names a solution — forecloses other ways to solve the same need.

Quick check

Which is the best-scoped HMW question, given the insight "new sellers abandon listing at the pricing step because they don't know competitive prices"?

3

Generating Ideas at Product Scale

Beyond open brainstorming, a few sources reliably produce stronger product ideas by pulling from outside the room or forcing a new angle.

Analogous inspiration

Borrow a proven pattern from a different industry solving a structurally similar problem.

Constraint-based ideation

"What if we had zero budget?" or "shipped in a day?" — artificial limits force unconventional ideas.

Mining customer language

Read support tickets and reviews for recurring suggestions — then reframe as an HMW, not a literal build order.

A team studying restaurant reservation apps for inspiration on their own healthcare booking flow is using which technique?

Desirability, Feasibility, Viability

Once you have concepts, judge each on three lenses. A strong idea clears all three reasonably well — acing just one isn't enough.

Desirability

Do users actually want this? Grounded in research, not a hunch.

Feasibility

Can we build it with the technology, skills, and time we have?

Viability

Does it make sense for the business — cost, revenue, strategic fit?

Quick check

A brilliant idea scores extremely high on desirability but the team has no way to build it with current technology or skills. What lens is failing?

Practice Scenarios

15 situations that test whether you can scope a How Might We question, pick the right ideation source, or spot which evaluation lens is failing.

Scenario 1

A team skips writing a How Might We question and jumps straight from "users are confused at checkout" to brainstorming feature ideas.

What's the risk?

Scenario 2

An HMW question reads: "How might we build a loyalty points system?"

What's wrong with it?

Scenario 3

A fintech team studies how airlines handle overbooking and delay compensation while ideating a refund-dispute feature.

What technique is this?

Scenario 4

A team is stuck and someone proposes: "What if we had to ship this with zero engineers, just no-code tools, by Friday?"

What technique is being used?

Scenario 5

An idea scores high on feasibility and viability, but user interviews consistently show nobody wants it.

Which lens is failing?

Scenario 6

A concept clears desirability and feasibility easily, but the cost to build and maintain it exceeds any plausible revenue.

Which lens is failing?

Scenario 7

A PM mines support tickets and finds many customers requesting "please let us export to Excel."

What's the ideation-framework move?

Scenario 8

A team writes an HMW so broad — "how might we make our product better?" — that the brainstorm produces unrelated ideas from everyone.

What's the fix?

Scenario 9

A team has three concepts. One is highly desirable and feasible, but relies on giving the product away free — a model the company can't sustain.

What should happen?

Scenario 10

A team generates fifty ideas from an HMW question but has no way to organize or evaluate them.

What's the next funnel step?

Scenario 11

A team ideating a checkout improvement studies how video-game stores handle one-click, saved-payment purchases.

What kind of ideation source is this?

Scenario 12

A stakeholder says an idea "feels desirable" based on their own personal preference, with no user research behind it.

What's the concern?

Scenario 13

A team's ideation funnel has no insight feeding the top — ideas are generated from a leadership offsite with no research behind them.

What's the risk?

Scenario 14

Two concepts tie on desirability and feasibility. One is a much bigger strategic bet; the other a small, safe improvement.

What should break the tie?

Scenario 15

A team develops a concept fully — mockups, spec, cost estimate — before ever writing a How Might We question or gathering an insight.

What went wrong with their process?

The Ideation Funnel

1

Insight

Validated finding from research.

2

How Might We

The insight, reframed as an open question.

3

Ideas

A wide set, quantity over quality.

4

Concepts & shortlist

Fleshed out, evaluated, ranked.

Writing a Good HMW

Grounded in a real insight

Not invented from thin air.

Not too broad

"Improve retention" points nowhere specific.

Not too narrow

Don't pre-load the solution into the question.

Sources for Ideas

Analogous inspiration

Borrow a pattern from another domain.

Constraint-based ideation

Add an artificial limit to force new angles.

Mining customer language

Reframe requests as insight, not literal specs.

Evaluating Concepts

Desirability

Do users actually want it?

Feasibility

Can we build it?

Viability

Does it work for the business?
