PLM, BOM & Digital Thread worked example

EBOM to MBOM Gap with line items present in the current mbom of 63 value: a worked example

This worked example runs the ebom to mbom gap numbers for a tougher week than the baseline: line items present in the current mbom of 63 value instead of the typical 125 value. Estimate ebom to mbom gap for plm, bom and digital thread using production-ready inputs so teams can measure the gap between available and required amounts.

The inputs for this scenario

  • Line items present in the current MBOM: 63 value (the input this scenario stresses; the baseline uses 125)
  • Line items expected from the released EBOM: 100 value (held at the documented default)
  • Reference EBOM line-item baseline: 100 value (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Ebom to mbom gap amount gap = available ebom to mbom gap amount - required ebom to mbom gap amount.
  • Ebom to mbom gap margin works out to -37 % at these inputs, and this is the headline figure for the scenario.
  • Ebom to mbom gap amount gap works out to -37 value at these inputs.
  • Available ebom to mbom gap amount works out to 63 value at these inputs.
  • Required ebom to mbom gap amount works out to 100 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line items present in the current mbom sits at 125 value and the headline result is 25 %, this scenario comes in 248% below the baseline at -37 %.
  • Use it during BOM reconciliation, after an engineering change, or before a production release to confirm the MBOM matches the EBOM intent. 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

  • Ebom to mbom gap margin: -37 % (headline result)
  • Ebom to mbom gap amount gap: -37 value
  • Available ebom to mbom gap amount: 63 value
  • Required ebom to mbom gap amount: 100 value

Run it with your numbers

  • To rerun this with your own numbers, open the live EBOM to MBOM Gap calculator, set line items present in the current mbom to your actual value, and adjust the remaining inputs to match your operation.
