Storeroom Inventory Accuracy at 70% target storeroom inventory accuracy: a worked example

This worked example runs the storeroom inventory accuracy numbers for a tougher week than the baseline: 70% target storeroom inventory accuracy instead of the typical 97%. Measure storeroom inventory accuracy by comparing accurate cycle-count lines with the total MRO parts lines counted.

The inputs for this scenario

  • Cycle-count lines matching system on-hand balance: 920 count (held at the documented default)
  • Total MRO inventory lines counted: 1,000 count (held at the documented default)
  • Target storeroom inventory accuracy: 70 % (the input this scenario stresses; the baseline uses 97)

Working through the calculation

  • The calculation starts from the formula this tool documents: Storeroom Inventory Accuracy rate = cycle-count lines matching system balance ÷ MRO inventory lines counted × 100.
  • Storeroom Inventory Accuracy rate works out to 92 % at these inputs, and this is the headline figure for the scenario.
  • Storeroom Inventory Accuracy gap to target works out to -22 points at these inputs.
  • cycle-count lines matching system balance works out to 920 count at these inputs.
  • MRO inventory lines counted works out to 1,000 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target storeroom inventory accuracy sits at 97% and the headline result is 92 %, this scenario lands almost exactly on the baseline at 92 %.
  • Use it after each cycle-count cycle or monthly storeroom audit to track whether record accuracy is trending toward your reliability target. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Storeroom Inventory Accuracy rate: 92 % (headline result)
  • Storeroom Inventory Accuracy gap to target: -22 points
  • cycle-count lines matching system balance: 920 count
  • MRO inventory lines counted: 1,000 count
