S&OP, Demand Planning & Forecasting worked example

Schedule Stability Score with severity of schedule change impact of 15 score: a worked example

This scenario runs the schedule stability score calculation on the strong side: severity of schedule change impact of 15 score, with every other input held at its documented default. Use it when schedule stability in s and op, demand planning and forecasting needs a defensible ranking against other s and op, demand planning and forecasting risks for the next review.

The inputs for this scenario

  • Severity of schedule change impact: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood of schedule change occurring: 4 score (unchanged)
  • Ability to detect the change before it hits: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Schedule stability risk score = schedule stability severity score × schedule stability occurrence score × schedule stability detection score) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for schedule stability risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for schedule stability severity score.
  • At this operating point the engine returns 4 score for schedule stability occurrence score.
  • At this operating point the engine returns 3 score for schedule stability detection score.

How this compares with the baseline

  • Against the tool's baseline example, where severity of schedule change impact sits at 6 score and the headline result is 4.55 score, this scenario comes in 79.12% above the baseline at 8.15 score.
  • Use it to prioritize which schedule-instability drivers to mitigate during S&OP or master-scheduling reviews. 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
