Following our chat - aim to create a document regarding assumptions guidance.

Section 1: Background of Assumptions

• Why they're important in theory.

• Why they help the end user.

Section 2: Best Practice of Assumptions

• Point value and range.
• Justification of value and range (link evidence)
• Quality Calculation + Justification
• Impact Calculation + Justification
• Risk Calculation (Quality * Impact) + mitigation activities where relevant
• Location within model (automated)
• Who changed what, when and why (automated)

Section 3: Further Considerations
