Which of the following factors would typically represent period demand?

Period demand typically refers to the anticipated demand for a product within a specific time frame. This demand is influenced by several factors including forecasts (predictions based on historical data and market analysis), customer orders (actual demand from customers), and promotions (marketing activities designed to boost sales). These elements together provide a comprehensive view of the expected demand during a particular period. Other factors like on-hand inventory and product life cycle influence supply chain decisions but do not directly represent period demand.
