To achieve increased profits, a company must balance inventory investment with order-fill rates. High order-fill rates often require maintaining higher levels of inventory to meet customer demand promptly, which can increase inventory holding costs. Conversely, minimizing inventory investment might lead to stockouts and lower order-fill rates, resulting in lost sales and customer dissatisfaction. Therefore, effective supply chain management involves finding an optimal balance where inventory levels are sufficient to meet demand without incurring excessive costs, thus enhancing profitability. This balance does not directly conflict with plant capacity, sales volume, or lead times as critically as it does with order-fill rates.References: Chopra, S.,

Demand planning involves forecasting future customer demand to inform production and inventory decisions.
The primary output of demand planning is product family and item forecasts, which provide detailed projections of future demand for different products or groups of products. These forecasts are critical for ensuring that the supply chain can meet customer demand efficiently and effectively.
