PLM, BOM & Digital Thread worked example

EBOM to MBOM Gap with line items present in the current mbom of 310 value: a worked example

This scenario runs the ebom to mbom gap calculation on the strong side: line items present in the current mbom of 310 value, with every other input held at its documented default. Use it when ebom to mbom gap in plm, bom and digital thread needs a clean margin number for a plm, bom and digital thread go / no-go review.

The inputs for this scenario

  • Line items present in the current MBOM: 310 value (raised for this scenario; the documented default is 125)
  • Line items expected from the released EBOM: 100 value (unchanged)
  • Reference EBOM line-item baseline: 100 value (unchanged)

Working through the calculation

  • Applying the documented formula (Ebom to mbom gap amount gap = available ebom to mbom gap amount - required ebom to mbom gap amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 % for ebom to mbom gap margin, the number this scenario is built around.
  • At this operating point the engine returns 210 value for ebom to mbom gap amount gap.
  • At this operating point the engine returns 310 value for available ebom to mbom gap amount.
  • At this operating point the engine returns 100 value for required ebom to mbom gap amount.

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 740% above the baseline at 210 %.
  • Use it during BOM reconciliation, after an engineering change, or before a production release to confirm the MBOM matches the EBOM intent. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Ebom to mbom gap margin: 210 % (headline result)
  • Ebom to mbom gap amount gap: 210 value
  • Available ebom to mbom gap amount: 310 value
  • Required ebom to mbom gap amount: 100 value
