A project schedule can contain every major task and still miss the work that connects them. Equipment is delivered, but installation drawings are unfinished. Construction is complete, but commissioning staff cannot access the site. The promised opening date depends on those handovers, not merely on whether individual teams finish their own listed activities.
Define usable completion
A task is complete for the next team when the necessary information, access and conditions are available. That definition may differ from the producing team's internal milestone. Agreeing acceptance criteria at each important handover helps prevent a completed status from concealing work that remains unusable, especially when several contractors operate with different reporting systems and incentives.
Expose the waiting time
Schedules often show productive activity more clearly than the intervals between activities. Review periods, transport arrangements and customer approvals can consume significant time without appearing as obvious work packages. Giving those intervals an owner and a realistic duration makes the schedule more credible and reveals where early preparation could shorten the overall path to operation.
Test the sequence
A joint planning session can walk through the first day after each major handover. Who arrives, what do they need and what would stop them starting? This practical exercise often identifies dependencies that a high-level chart overlooks. It also allows teams to agree a workable sequence before delays force hurried decisions under customer pressure.
Report the joins
Progress reviews should include upcoming handovers and their readiness, rather than only completed percentages. That gives management an earlier view of execution risk. A delivery promise becomes stronger when the organisation can explain how work moves between teams and show that the next recipient is prepared to accept it when the schedule says it should arrive.
