PM Labor Capacity at 23% route, lockout, access, documentation, and parts staging allowance: a worked example

Push route, lockout, access, documentation, and parts staging allowance up to 23% and the picture changes. This example computes every intermediate figure at that operating point. a maintenance or asset-management team needs to confirm PM coverage with available technicians or rebalance intervals and routes for a PM planning window

The inputs for this scenario

  • PM tasks due in the planning period: 420 PM tasks (unchanged)
  • PM tasks completed per technician hour: 4.6 PM tasks / hr (unchanged)
  • Route, lockout, access, documentation, and parts staging allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base PM labor capacity time = PM tasks due in the planning period รท PM tasks completed per technician hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 112 hr for required pm labor capacity time, the number this scenario is built around.
  • At this operating point the engine returns 91.3 hr for base pm labor capacity time.
  • At this operating point the engine returns 23 % for route, lockout, access, documentation, and parts staging allowance applied.
  • At this operating point the engine returns 4.6 pieces / min for pm tasks completed per technician hour.

How this compares with the baseline

  • Against the tool's baseline example, where route, lockout, access, documentation, and parts staging allowance sits at 20% and the headline result is 110 hr, this scenario comes in 2.5% above the baseline at 112 hr.
  • It converts the number of PM tasks due into required technician labor hours by dividing by the completion rate and inflating the result by an allowance for surrounding non-productive time. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required PM labor capacity time: 112 hr (headline result)
  • Base PM labor capacity time: 91.3 hr
  • route, lockout, access, documentation, and parts staging allowance applied: 23 %
  • PM tasks completed per technician hour: 4.6 pieces / min
