Scope leakage
The team performs work that is outside the priced or documented baseline, but the commercial process does not capture the change with the same speed as field execution.
Revenue leakage
Earned or approved value gets delayed, missed, underbilled, disputed, or left outside the billing process even though cost has already been incurred.
Cost leakage
Rework, inefficiency, escalation, unplanned supervision, subcontract extras, and poor coding can consume margin without being tied back to the condition that caused them.
Forecast leakage
Unsupported assumptions hide the future effect of known issues, causing leadership to react after the exposure has already hardened.
Control leakage
When ownership, cadence, and escalation are inconsistent, open items age. The absence of a review rhythm becomes a profitability condition of its own.
