Product Ideation Expert

Overview

Structured product ideation for both new product creation and existing product enhancement. This skill combines the Product Trio approach (PM + Designer + Engineer perspectives) with Teresa Torres' Opportunity Solution Tree framework to generate, evaluate, and prioritize product ideas systematically.

When to Use

• New Product Ideation -- Exploring greenfield opportunities where the focus is on core value delivery, speed to validate, and market differentiation.
• Existing Product Enhancement -- Identifying opportunities within a live product using the Opportunity Solution Tree to connect desired outcomes to concrete solutions.

Methodology

Phase 1: Frame the Problem Space

Before generating ideas, establish clarity on the context:

1. Define the Target Outcome -- What measurable result are we trying to achieve? (e.g., increase activation rate by 15%, reduce churn by 10%)
2. Identify the Target Segment -- Who specifically are we solving for? Include behavioral and situational context, not just demographics.
3. Map Known Constraints -- Budget, timeline, technical platform, regulatory requirements, team capacity.

Phase 2: Product Trio Ideation

Generate 5 ideas from each of the three perspectives (15 total):

Product Manager Perspective (5 ideas) Focus: Business value, market positioning, customer pain points, strategic alignment

• What problems do customers report most frequently?
• Where are competitors weak that we could be strong?
• Which segments are underserved by current solutions?
• What would make customers willing to pay more or switch?
• How does this connect to our strategic objectives?

Designer Perspective (5 ideas) Focus: User experience, workflows, accessibility, delight, friction reduction

• Where do users drop off or struggle in current flows?
• What tasks take too many steps or too much cognitive load?
• How could we surprise users with unexpected value?
• What accessibility gaps exist that exclude potential users?
• Where can we reduce time-to-value for new users?

Engineer Perspective (5 ideas) Focus: Technical feasibility, scalability, platform capabilities, integration opportunities

• What new capabilities does our tech stack enable?
• Which features could we build quickly with high impact?
• Where could automation replace manual processes?
• What data do we have that we are not leveraging?
• Which technical debt, if resolved, would unlock new possibilities?

Phase 3: Approach by Product Type

For New Products

Apply these lenses to each idea:

For Existing Products (Opportunity Solution Tree)

Follow Teresa Torres' Continuous Discovery Habits framework:

Desired Outcome
├── Opportunity 1 (unmet need / pain point / desire)
│   ├── Solution A
│   ├── Solution B
│   └── Solution C
├── Opportunity 2
│   ├── Solution D
│   └── Solution E
└── Opportunity 3
    ├── Solution F
    └── Solution G

1. Start with the outcome -- The metric or business result you want to move.
2. Map opportunities -- Interview-driven insights about what customers need, want, or struggle with.
3. Generate solutions per opportunity -- Each opportunity gets multiple potential solutions.
4. Compare and select -- Evaluate solutions within the same opportunity branch, not across branches.

Phase 4: Prioritize Top 5

From the 15 generated ideas, select the top 5 using this scoring model:

Weighted Score = (Impact x 0.30) + (Strategy x 0.25) + (Feasibility x 0.20) + (Speed x 0.15) + (Differentiation x 0.10)

Phase 5: Document Each Idea

For each of the top 5 prioritized ideas, produce:

Supplementary Techniques

When the trio needs additional stimulus:

• SCAMPER -- Substitute, Combine, Adapt, Modify, Put to other use, Eliminate, Reverse. Apply to existing products or competitor features.
• How Might We (HMW) -- Reframe problems as opportunity questions. "Users churn after trial" becomes "How might we demonstrate value before the trial ends?"
• Crazy 8s -- 8 sketches in 8 minutes per person. Forces breadth over depth.
• Worst Possible Idea -- Generate deliberately bad ideas, then invert them to find hidden good ones.

See references/ideation-frameworks.md for detailed descriptions of each technique.

Integration with Other Discovery Skills

• After ideation, move top ideas to identify-assumptions/ to map and prioritize assumptions.
• Use brainstorm-experiments/ to design validation experiments for key assumptions.
• Run pre-mortem/ before committing to build, to surface hidden risks.

Troubleshooting

Success Criteria

• Each ideation session produces at least 15 ideas across all three Product Trio perspectives (minimum 3 per perspective)
• Top 5 prioritized ideas each have a documented riskiest assumption and a validation plan
• At least 60% of prioritized ideas can begin validation within 2 weeks using lightweight methods
• Stakeholders rate the ideation output as "relevant to strategic objectives" at 4+/5
• Ideas that proceed to validation have a clear connection to the target outcome (traceable through the Opportunity Solution Tree)
• Ideation cadence is maintained (at minimum quarterly for existing products, monthly during new product exploration)
• At least 1 idea per quarter advances from ideation through validation to backlog commitment

Scope & Limitations

In Scope: Structured ideation facilitation using Product Trio approach, Opportunity Solution Tree mapping, idea prioritization with weighted scoring, SCAMPER and HMW supplementary techniques, idea documentation with validation plans, integration with downstream discovery skills.

Out of Scope: Assumption testing and experiment design (hand off to brainstorm-experiments/ and identify-assumptions/), detailed product requirements (hand off to execution/create-prd/), market research and competitive analysis, financial modeling for ideas.

Limitations: Ideation quality is bounded by the diversity of perspectives in the room -- remote-only sessions may reduce creative energy. Scoring models provide structured comparison but are not objective truth; they encode the biases of the scorers. Opportunity Solution Trees require ongoing user research to populate -- they are not a substitute for customer interviews.
