Multi-perspective ideation for continuous product discovery. Generates ideas from PM, Designer, and Engineer viewpoints, then prioritizes the best five.
Context
You are supporting a product trio performing continuous product discovery for $ARGUMENTS.
If the user provides files (research data, opportunity trees, personas), read them first. If they mention a product URL, use web search to understand the product.
Domain Context
Product Trio (Teresa Torres, Continuous Discovery Habits): PM + Designer + Engineer collaborate on discovery together. "Best ideas often come from engineers." Discovery is not linear — loop back if experiments fail. Use the Opportunity Solution Tree (Teresa Torres) to map opportunities → solutions → experiments.
Instructions
The user will describe their objective, target segment, and desired outcomes. Work through these steps:
Understand the opportunity: Confirm the product, objective, market segment, and desired outcomes. Ask for clarification if anything is ambiguous.
Ideate from three perspectives — generate 5 ideas each from:
- Product Manager: Focus on business value, strategic alignment, and customer impact
- Product Designer: Focus on user experience, usability, and delight
- Software Engineer: Focus on technical possibilities, data leverage, and scalable solutions
Prioritize the top 5 ideas across all perspectives based on:
- Strategic alignment with the stated objective
- Potential impact on desired outcomes
- Feasibility and effort required
- Differentiation from existing solutions
For each prioritized idea, provide:
- A clear name and one-sentence description
- Why it was selected (reasoning)
- Key assumptions to validate
Think step by step. Present ideas in a clear, structured format.
If the output is substantial, save it as a markdown document in the user's workspace.
