Demand forecast
A demand forecast is an estimate or prediction of the quantity of a product, service, or resource that will be needed during a specified future period.
Demand Forecasting Best Practices
A demand forecast is a prediction of future demand for a product, service, or item over a specified period.
- How it is used
- Supports supply-chain decisions about purchasing, production, shipping, storage, and inventory.
- How deep it goes
- Defines unconstrained demand and distinguishes it from sales, supply plans, budgets, targets, aggregation, horizons, and bias.
- Examples
- Uses an ice cream truck to contrast predicted demand, constrained sales, replenishment, and recurring stockouts.
- What you can do after
- Evaluate/understand whether a forecast represents customer demand rather than a constrained plan, target, budget, or sales history.

Machine Learning System Design
Demand forecasting is the process of estimating future demand for a product or service over a specified time period.
- How it is used
- Supports retail purchasing decisions by estimating demand per SKU per store before goods are delivered.
- How deep it goes
- Develops the problem through data selection, several baselines, and batch-serving plans rather than a detailed forecasting-algorithm derivation.
- Examples
- Uses a multi-store retailer, an item’s sales one week earlier, and progressively richer forecasting baselines.
- What you can do after
- Operate/configure it as scheduled batch forecasting with scalable jobs and checks on data, failures, and prediction accuracy.
