When to use it
A useful fit
Use it when agreeing a budget, evaluating risk responses or deciding whether a forecast can be supported by available funding.
Know the limits
Do not treat a calculated average risk exposure as a guarantee of sufficiency. Reserve conventions vary, so define your organisation’s terms.
How to use it
- Separate planned work from identified risk exposure and other funding provisions.
- Document how each reserve is sized and who can approve its use.
- Track releases, remaining funds and remaining exposure together; update approvals when needed.
Worked example
A testing delay requires additional specialist support. The manager identifies the related risk, requests the appropriate reserve release and records both the funding used and the remaining exposure. The original work estimate is not silently rewritten.

Common pitfalls
Using reserve quietly to mask an overrun prevents the sponsor from seeing whether risk protection is disappearing.
