01
Rebuild the current list from the recorded changes
Start with the six baseline identifiers. Remove F, then add G and H. The current scope is A, B, C, D, E, G and H, containing seven tasks. The count also follows from six minus one plus two, which equals seven. Keep F in the change record with its removed status; do not mark it completed merely because it no longer appears in the current list. The change record explains why the current scope differs from the baseline and prevents a missing identifier from being mistaken for an accidental omission.
02
Reconcile completion against the current scope
The completed set remains A, B and C because the scope change did not alter their status. The current unfinished set is D, E, G and H, containing four tasks. Three completed plus four unfinished equals the seven-task current scope. Before the revision there were three unfinished tasks; afterward there are four. That increase does not undo the three completions. It reflects one unfinished removal and two unfinished additions. A single remaining-count chart would not explain the difference unless it also showed the scope decisions that changed the underlying list.
03
Save a handoff with both versions and the reason
A reusable scope sheet records the baseline version, baseline identifiers, completed identifiers, additions, removals, current scope and current unfinished set. Add a reason and decision date for each change. For this example, the next work is D, E, G and H, while F remains recorded as removed. If a later revision changes a completed task substantially, decide explicitly how to represent the new work rather than silently preserving its completed status. The worksheet counts items, not effort or value, so any workload estimate belongs in a separate field with its own assumptions.
