Schedule Management

Plans, develops, manages, and controls the project schedule.

established project management guidelines definition

Project Schedule Management includes the processes required to manage the timely completion of the project. The work products include a schedule management plan, the schedule baseline, a milestone list, and the project schedule itself. Schedule management defines activities, sequences them, estimates durations, develops the integrated schedule, and controls schedule variance.

Processes in this Knowledge Area

Plan Schedule Management

Outputs: schedule management plan.

REQ-FUN-108 — Schedule template instantiation seeds activities + dependencies

Define Activities

Outputs: activity list, activity attributes, milestone list.

REQ-FUN-101 — Schedule activity CRUD scoped to project and work package

Sequence Activities

Outputs: project schedule network diagrams.

REQ-FUN-102 — Activity dependency model (FS/SS/FF/SF + lag/lead in days)

Estimate Activity Durations

Outputs: duration estimates, basis of estimates.

No AI_PM requirements primarily mapped to this process.

Develop Schedule

Outputs: schedule baseline, project schedule, schedule data.

REQ-FUN-103 — Critical-path computation triggered on schedule change
REQ-FUN-104 — Schedule baseline (versioned, immutable snapshot)
REQ-NFR-067 — Critical-path computation p95 <= 500 ms at 500 activities
REQ-NFR-068 — Baseline rows insert-only at DB role level (schedule + cost)
REQ-NFR-072 — Schedule recalculation p95 <= 1 s on activity edit

Control Schedule

Outputs: work performance information, schedule forecasts, change requests.

REQ-FUN-105 — Schedule slippage detection vs approved baseline
REQ-FUN-107 — Schedule report (variance + SPI by project / WBS branch / time window)
REQ-FUN-109 — Activity status updates via dedicated activity_status_update rows
REQ-FUN-110 — Auto-create board item when activity deps are satisfied
REQ-FUN-111 — Per-activity forecasted finish date from EV + SPI
REQ-FUN-112 — Resource over-allocation flag (read-only, no auto-leveling)
REQ-FUN-113 — Post-baseline schedule changes require approved Change Request
REQ-FUN-114 — Schedule export in iCalendar (ICS) and CSV formats
REQ-FUN-106 — Read-only Gantt chart view of project schedule
REQ-NFR-071 — Gantt view legible at up to 200 activities (desktop)
