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:

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

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?
Viability: Can we sell/monetize/finance it? Is it worth the cost? Can we support customers and help them succeed? Can we scale? Will it be compliant?
Feasibility: Can we do it with the current technology? Is this integration possible? Can it be efficient? Can we scale it?
Ethics: Should we do it at all? Are there any ethical considerations? Will it pose a risk for our customers?
Go-to-Market (especially critical for new products): Can we market it? Do we have the required channels? Can we convince customers to try it? Is this the right messaging for this channel? Is this the right time? Is this the right way to launch it?
Strategy & Objectives: What are our assumptions? Can others copy our strategy? Have we considered political, economic, legal, technological, and environmental factors? Are those the best problems to solve?
Team: How well will the team work together? Do we have the right people? Do we have the right tools? Will the entire team stay with us long enough?

For each assumption, rate confidence and suggest a test.
