Measurement uncertainty
A budget is only worth what its weakest contribution can be traced to. I build budgets to the GUM and, more often, review budgets that already exist — against the measurement they actually support, and against the scope you hold.
What you get
- A documented budget with every contribution, its distribution, and the source it rests on
- Sensitivity coefficients and how they were derived, written down rather than assumed
- A stated basis for each Type B contribution, so an assessor can follow it without asking
- A short review memo naming what I would change and in what order
Right call when
You are adding a scope, the person who wrote the budget has left, or an assessor has questioned a contribution.
