A delayed trade should change a plan you can explain
Consider a window delivery that arrives after the planned installation date. Identify the affected activity, inspect its successors and revise the schedule deliberately. Compare the result with the baseline and check which commitments to the homeowner or other trades need a conversation. A recalculated date is not the same as a supplier confirming availability.
The schedule does not replace workforce allocation. Its working calendar and the separate workforce planner have different responsibilities. Do not assume that moving an activity automatically reserves a crew, changes an absence or resolves a subcontractor clash.
