This process group covers how assets are kept available and fit for purpose after they are in service, beginning with maintenance planning. Planning work includes setting maintenance strategies and policies, analysing asset condition and predicting what maintenance will be needed, folding preventive work into the operations schedule, identifying tasks and their priorities, planning resources and producing work plans. It then covers management of maintenance activity through scheduling of work, securing the required resources, quality control, updating work and asset records, managing safety during maintenance, and setting performance targets and tracking delivery against those targets and any contracts. Execution is covered last, spanning preventive, routine and corrective maintenance and repairs, along with spotting unplanned maintenance needs and carrying that unplanned work out.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
