FAQ
Frequently asked questions
What is the difference between demand forecasting and demand planning?
Demand forecasting predicts future demand statistically. Demand planning adds business assumptions, aligns teams, and translates the forecast into inventory and purchasing decisions.
Can VOIDS plan campaigns and product launches?
Yes. Campaigns, events, launches, and growth targets can be modeled as demand effects by product, channel, and period.
Does VOIDS replace spreadsheets for demand planning?
Yes, for recurring planning workflows. VOIDS replaces disconnected spreadsheet versions with a shared forecast, assumptions, inventory impact, and purchasing actions.
