Schedule Management Plan

Scheduling standards

• All portfolio milestones must be traceable to a WBS element and owner
• Dependencies must be explicit (FS/SS/FF relationships where applicable)
• Critical milestones must have acceptance criteria and “definition of done”
• Dates are forecasted based on evidence (site readiness, approvals, procurement signals)

CPM methodology

• Critical path updated weekly
• Near-critical band tracked (≤ 10 working days total float)
• Float erosion flagged as early warning even if dates remain unchanged

Baselines & change control

• Baseline set post-planning gate; changes require impact narrative
• Any milestone movement affecting committed dates triggers Change Impact Analysis
• Re-baseline only when scope changes or assumptions materially shift

Cadence

• Weekly: IMS updates + critical path refresh + risk checks
• Bi-weekly: dependency closure review
• Monthly: executive dashboard + forecast confidence review

Escalation thresholds

• Committed date risk > 5% probability or > 10 working days slip forecast
• Total float drops below 5 working days on any critical milestone
• Dependency breaches: downstream start blocked with no approved recovery
