CIP sits at the intersection of the largest number of functions and the smallest amount of shared accountability. Facilities commissions work. Procurement issues purchase orders. Project managers know when the work is done. Accounting knows how to capitalize. Tax cares about classification. Nobody, typically, has a standing obligation to tell anyone else when the state of a project has changed.
That gap produces the three findings that appear in nearly every CIP review: projects that never close, in-service dates set by convenience rather than readiness, and one asset line where there should have been forty.
None of that is negligence. It is the predictable result of a process whose handoffs were never designed. Which is also why it is fixable — with lifecycle stages that mean something, a placed-in-service policy with a name attached to it, componentization decided at project setup instead of project close, CIP aging in front of leadership every month, and monthly reconciliation instead of an annual reconstruction.
