# Assumptions Mapping

## The What

Assumptions Mapping is used to find and check assumptions based on desirability, feasibility, and viability. It helps teams focus on testing high-risk assumptions, lowers uncertainty, and improves decision making.

## The How

Access the hypotheses: **Desirability**: Does the market want this idea? **Feasibility**: Can we deliver at scale? **Viability**: Is the idea profitable enough?

Map out **Evidence** vs **Importance**

Verify the top right quadrant where **critical assumptions** with little evidence are found

Not all hypotheses are equally important; some may not be critical to the business idea's success

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://jamiewen00.gitbook.io/tech-lead-handbook/product/assumptions-mapping.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
