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.
