Manufacturing Master Data & Data Governance worked example

Data Error Cost at 25% errors reaching downstream: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop errors reaching downstream to 25%, then walk the calculation through step by step. Estimates the financial exposure from bad master or transactional data flowing through manufacturing systems.

The inputs for this scenario

  • Erroneous transactions per period: 1,800 transactions (held at the documented default)
  • Rework cost per error: 42 $/error (held at the documented default)
  • Errors reaching downstream: 25 % (the input this scenario stresses; the baseline uses 35)
  • Monitoring and audit overhead: 5,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total = error transactions x rework cost x escape% + monitoring overhead.
  • Total data error cost works out to 23,900 $ at these inputs, and this is the headline figure for the scenario.
  • Data error cost per unit works out to 13.28 $ / piece at these inputs.
  • Variable data error cost works out to 18,900 $ at these inputs.
  • Fixed data error cost adder works out to 5,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where errors reaching downstream sits at 35% and the headline result is 31,460 $, this scenario comes in 24.03% below the baseline at 23,900 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to errors reaching downstream, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses one blended rework cost and a single escape percentage; the most damaging errors that trigger recalls, chargebacks or lost customers cost far more than the average and should be modeled separately.

Results at a glance

  • Total data error cost: 23,900 $ (headline result)
  • Data error cost per unit: 13.28 $ / piece
  • Variable data error cost: 18,900 $
  • Fixed data error cost adder: 5,000 $
