3.15 Task Analysis and MRD
Objectives
Outline Defence policy and procedures on:
  • Task Analysis (TA)
  • Failure Modes Effects and Criticality Analysis (FMECA)
  • Reliability Centred Management (RCM)
  • Resource Requirements
Each Support System uses resources to maintain the Mission System
Resources such as:
  • spares,
  • Support &Test Equipment (S&TE),
  • packaging,
  • manuals etc
  • skilled people
To understand what resources are required we need to evaluate the Materiel System. Task Analysis, which determines all the support tasks that are conducted against the following subjects:
  • Resource Evaluations and Tradeoffs
  • Level of Repair Analysis
  • Spares Optimisation
  • Resource Packaging
  • Rolling up resources from the task to system level
Task Analysis identifies, determines and documents all resource requirements for:
  • Operations
  • Maintenance
  • Other support tasks
  • For the Mission System and the relevant components of the Support System e.g.. Simulators and training equipment
Task Analysis uses the results of:
  • Failure Modes Effects & Criticality Analysis (FMECA)
  • Failure Modes Effects Analysis (FMEA)
  • Reliability Centred Maintenance (RCM)
  • Functional Flow & Human System Integration
  • Recorded within the Task Inventory
To conduct a Task Analysis, the Maintenance Policy must be set, which will include:
  • What is to be maintained
  • Where it is to be maintained
  • When it is to be maintained
  • Who is responsible for maintaining it
  • How it is to be maintained
Task Analysis may result from other processes, such as RCM.
  • Reliability Centred Maintenance is used to determine the most Applicable Task, and the most Effective Interval of when that task should be performed.  RCM provides the “WHAT” and “WHEN” of the items Maintenance Policy.
