Fragile Spots (Critical Assumptions)

Every assumption that could break the plan is marked as fragile.

Examples:

• “Assume API gives full history”
• “Assume credit score provider can refresh daily”
• “Assume legal allows upsell banner”

These must be tested in the first sprint.

They are not risks, they are guaranteed sources of rework unless tested.

Activities

• Short assumption review
• Assign testing/ownership

Frameworks / Tools

• Assumption mapping (importance vs evidence)
• Risk radar
• Technical debt register

Outputs

• Critical assumptions map
• Fragility register
• Owners + actions to de-risk early
