Demand Forecasting Best Practices
Sales are completed transactions or the quantities of products or services sold during a specified period.
- How it is used
- Distinguishes constrained sales from demand when collecting data and setting forecasting targets.
- How deep it goes
- Explains the stockout feedback loop and practical censoring of shortage periods, without detailing forecasting-model implementation.
- Examples
- Uses an ice cream truck stockout and an online product's inventory-and-sales history.
- What you can do after
- Evaluate/understand when sales are valid demand evidence and when shortages require order collection or censoring.
