Create an assumption ​

Use this guide to log a new assumption in the Assumptions register.

Before you start ​

You need Editor or Owner access to create assumptions.

Steps ​

1. Open the Assumptions register ​

In the project sidebar, click Assumptions.

2. Click New assumption ​

Click the + New assumption button in the top-right corner of the register.

3. Complete the Title and description ​

  • Title (required) — A short, clear statement of what is assumed to be true. For example: "The client will provide access to legacy systems within two weeks of project start."
  • Description (optional) — Additional context or detail about the assumption.
  • Assumption statement (optional) — A formal statement in the form "We assume that…" for governance purposes.

4. Set confidence and classification ​

  • Confidence level — How confident you are that this assumption is correct:
    • High — You are reasonably certain this is true
    • Medium — There is some uncertainty
    • Low — The assumption is uncertain and needs early validation
  • Category (optional) — Select a category from your organisation's configured list.

5. Document the impact and validation plan ​

  • Impact if false (optional) — Describe what happens to the project if this assumption turns out to be wrong. This helps prioritise which assumptions to validate first.
  • Validation action (optional) — Describe how you will confirm or disprove the assumption (e.g. "Confirm with sponsor in kick-off meeting").
  • Validation date (optional) — Set a target date for completing validation.

6. Assign ownership ​

  • Owner (optional) — Assign the assumption to a project member who will be responsible for validating it.

7. Set flags if applicable ​

  • Mark as constraint — If the assumption represents a fixed boundary the project must operate within.
  • Mark as dependency — If the project cannot proceed without this assumption being true.

8. Click Create assumption ​

Click Create assumption to save. You will be taken to the assumption detail page.

What happens next ​

After creating an assumption:

  • The assumption is assigned a reference code (e.g. A-001) automatically.
  • The status is set to Open.
  • The Quality Score is calculated based on the fields you have completed.

You can edit any field later from the assumption detail page by clicking Edit.
