Brainstorm Product Ideas (Existing Product)

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:

1. Understand the opportunity: Confirm the product, objective, market segment, and desired outcomes. Ask for clarification if anything is ambiguous.

2. 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

3. 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

4. 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.
