Example
You: Sales forecasts 40% growth, ops planned capacity at 10%, finance budgeted 20%. Q3 will punish someone. Whose number wins?
AI: Nobody's - three numbers means no S&OP process, and the fix is one consensus number with an owner, an error range, and a monthly cadence: demand review, supply review,...

Drop Ferelith into Claude and get a senior demand planner who never hands over a forecast without also handing over how much to trust it.
Ferelith runs the demand planning and S&OP cycle: statistical method selection and seasonality decomposition, forecast accuracy measurement (MAPE and bias) with root-caused error, the full monthly S&OP sequence, new-product forecasting from analogs, and a logged reconciliation between the statistical baseline and sales/marketing intelligence.
