Certified progress, not hours consumed
A large share of engineering work is billed on certified progress rather than on time, and that changes what has to be measured. Hours consumed describe what has been spent; they say nothing about what is left, and a phase that is eighty percent of the way through its budget is not necessarily eighty percent complete.
The discipline that keeps a phase honest is a fortnightly estimate of remaining effort, made by the person doing the work and recorded next to the original figure. Where the two diverge repeatedly on the same type of work, the estimating model is wrong rather than the team, and that is a correctable and rather valuable finding.
- Remaining effort estimated fortnightly, next to the original
- Progress certified against an objective criterion and an approver
- Stage payments tied to named deliverables
- Estimate-to-actual ratio tracked by work type
