Plan on the signal, not last year plus a bit.
A proprietary ML forecast at channel and size level that re-learns from live sell-through, so every plan downstream starts from real demand and stays current all season.

Same role. Better week.
- Start the plan from last year plus a percentage
- Re-forecast manually, only when there's time at month-end
- Work from a forecast nobody downstream quite trusts
- Lose the new-style call to gut feel and look-alikes by hand
- Start from an ML forecast learned from every channel signal
- Re-forecast continuously on live sell-through, day and night
- One forecast the whole plan runs on, reconciled everywhere
- New styles forecast from look-alikes automatically
Your Demand agent never stops re-forecasting
