# Assumption

> Assumptions are one of the supported [Discovery Space](/guides/getting-started/the-discovery-space) card types.

## What is an Assumption Card?

An assumption is a belief accepted as true without definitive proof. Every proposed idea inherently contains multiple assumptions that should be identified and validated. Below are common categories of assumptions that teams should consider:

| **Assumption Type** | Description                                                                           |
| ------------------- | ------------------------------------------------------------------------------------- |
| **Desirability**    | Does this solution solve a meaningful problem for users, and will they want it?       |
| **Usability**       | Will users intuitively understand and successfully use this solution?                 |
| **Feasibility**     | Can this solution be delivered with the current team, resources, and capabilities?    |
| **Viability**       | Does this solution align with strategic goals and generate measurable business value? |

**Additional Considerations:**

| **Assumption Type**        | Description                                                                                                     |
| -------------------------- | --------------------------------------------------------------------------------------------------------------- |
| **Ethical Considerations** | Does this solution align with ethical standards and avoid potential harm to users, society, or the environment? |
| **Scalability**            | Can this solution grow to meet increasing demand without degrading quality or performance?                      |
| **Legal**                  | Are there legal considerations that might impact implementation or adoption?                                    |

<Note>
  While the first four assumption types are foundational to most product development efforts, the additional types should be evaluated when relevant to the specific solution context.
