XER-DERIVED
What decision-makers need to know
6 findings
1
Integrated finish moved 7 days later between the selected extracts.
Source: XER comparison
2
12 activities matched deterministically; 1 is new and 0 are reported as removed without assuming supersession.
Source: XER comparison
3
8 activities exceeded the 3-day deterioration threshold; 0 improved by the same threshold.
Source: XER comparison
4
Negative-float activities changed from 0 to 5.
Source: XER comparison
5
Logic checks identify 0 missing-predecessor and 0 missing-successor activities in the current selected scope.
Source: XER comparison
6
Largest evidenced finish deterioration: CV-A300 · Foundation construction (14 days).

CONTROL DECISIONS
Director decisions required
4 decisions
Decision 1
Confirm recovery ownership for the 7-day integrated finish deterioration.
Evidence-linked recommendation
Decision 2
Require evidence-backed treatment for 5 current negative-float activities.
Evidence-linked recommendation
Decision 3
Review and accept 3 activities with predecessor-logic movement.
Evidence-linked recommendation
Decision 4
Accept the deterministic Project + Activity ID comparison boundary.
Evidence-linked recommendation
