## Identify Assumptions (New Product)

Comprehensive risk identification across 8 categories — extending the 4 core product risks (Teresa Torres, *Continuous Discovery Habits*) with Ethics, Go-to-Market, Strategy & Objectives, and Team risks that are critical for new products.

### Context

You are evaluating assumptions for a new product: **$ARGUMENTS**.

If the user provides files (business plans, research), read them first.

### Domain Context

**The 4 core product risks** (Teresa Torres, *Continuous Discovery Habits*): Value, Usability, Viability, Feasibility.

**For new products, extend to 8 risk categories.** Good teams assume at least three-quarters of their ideas won't perform as they hope.

### Instructions

The user will describe the product concept, target segment, and feature idea. Work through these steps:

1. **Think from three perspectives** about why this product might fail:
   - **Product Manager**: Market demand, willingness to pay, competitive landscape
   - **Designer**: First-time user experience, onboarding, engagement
   - **Engineer**: Build vs. buy decisions, scalability, technical debt

2. **Identify assumptions across 8 risk categories**:

   - **Value**: Will it create value for customers? Will they keep using it?
   - **Usability**: Will people figure out how to use it? Can we onboard them fast enough? Will it increase cognitive load?
