Preventive maintenance: acting before the failure

Preventive maintenance schedules interventions before a failure appears, based on a period or a condition indicator. It turns an unplanned stop into a chosen one. The maintenance plan sets its content, its frequency and its workload.

The chosen stop rather than the imposed one

Preventive maintenance covers interventions scheduled before failure. Two logics trigger it: periodicity, based on running hours or the calendar, and condition, based on a measured indicator such as vibration, temperature or oil analysis. The maintenance plan sets its content, its frequency and the associated workload.

  • Triggered by periodicity or by a measured condition indicator
  • The plan sets the content, the frequency and the workload
  • A scheduled stop is prepared, tooled and held to the announced time

Two triggering logics

The Industrial Maintenance and Energy programme has candidates build a full plan for a fleet of equipment, with intervention schedules and the associated workload. The Networks and Cloud Computing programme applies the same logic to systems: update windows, health checks and planned switchover.

LogicWhat triggers itWhat it requires
PeriodicRunning hours or a calendar dateEquipment history and a written intervention schedule
Condition-basedA measured indicator: vibration, temperature, oil analysisSensors, a defined threshold and regular reading
Systematic after incidentAn event observed on identical equipmentExperience feedback shared between teams

Programmes that have you build a plan

2 catalogue programmes put “Preventive maintenance” to work: 240 credits and 2400 taught hours in total. The official rule holds throughout — one credit stands for 25 hours of work, 10 of them taught. Every line below is recomputed from the programme page: level, duration, credits, taught volume and fees in Guinean francs appear exactly as filed in the official catalogue.
