Equipment history is the accumulated, structured record of an asset's maintenance activity — work performed, failures experienced, parts consumed, costs incurred, and condition data collected — over its operating life.
Open resourceLifecycle Cost Analysis
Lifecycle cost analysis evaluates the present value of relevant costs — and, where included, benefits — over a defined analysis period to support defensible procurement, repair-versus-replace, and renewal decisions.
Open resourceWork Management

Maintenance management is the discipline of planning, organizing, controlling, and improving the work required to preserve asset function, spanning strategy selection, the work order lifecycle, planning and scheduling, and performance measurement.
Open resourcePlanning and Scheduling Governance
Planning and scheduling governance defines decision rights, readiness handoffs, freeze controls, dispute escalation, and shared data rules between maintenance planning and scheduling.
Open resourceSchedule Compliance
Schedule compliance measures completion against a frozen maintenance schedule while preserving baseline integrity, variance visibility, and anti-gaming controls.
Open resourceShutdown and Turnaround Planning
Shutdown and turnaround planning develops, challenges, freezes, and proves readiness of major-event scope before a finite execution window begins.
Open resourceShutdowns, Turnarounds & Outages
Shutdown, turnaround, and outage (STO) management is the governance layer that makes a major planned event run as one accountable program — steering committee, event manager, phase gates, a consolidated go/no-go, and governed contractor, cost, and lessons-learned control.
