Which of the following factors would typically represent period demand?

Period demand represents the total demand for an item over a specific time interval. It is an aggregation of various demand streams. The primary components used to calculate or project period demand are the statistical forecast (baseline demand), actual customer orders already received for that period (which consume the forecast), and any anticipated additional demand resulting from planned promotions, sales events, or other marketing activities.

A. On-hand inventory is a measure of supply, not a component of demand. Product life cycle is an input to forecasting strategy.
B. Product life cycle is a strategic consideration that influences the forecast, not a direct numerical component of period demand itself.
C. On-hand inventory is a supply-side factor and is not included in the calculation of demand.
