Demand Forecast Gap with forecasted or committed barrier-film demand of 63 value: a worked example in specialty films, membranes & barrier materials

This worked example runs the demand forecast gap numbers for a tougher week than the baseline: forecasted or committed barrier-film demand of 63 value instead of the typical 125 value. Estimate demand forecast gap for specialty films, membranes and barrier materials using production-ready inputs so teams can measure the gap between available and required amounts.

The inputs for this scenario

  • Forecasted or committed barrier-film demand: 63 value (the input this scenario stresses; the baseline uses 125)
  • Actual firm orders or consumption: 100 value (held at the documented default)
  • Baseline demand used for the comparison: 100 value (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where forecasted or committed barrier-film demand sits at 125 value and the headline result is 25 %, this scenario comes in 248% below the baseline at -37 %.
  • Use it in the S&OP or demand-review cycle to size forecast error, spot over- or under-forecasting, and decide whether to adjust production or inventory targets. 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

  • Demand forecast gap margin: -37 % (headline result)
