When planning inventory, one of the first steps is determining the gross requirements. Gross requirements represent the total amount needed for production based on customer demand, sales forecasts, and production plans.
They are essentially the "raw" demand figures before any adjustments for current inventory or any scheduled deliveries. Understanding gross requirements is crucial in forecasting, as they give a complete picture of what is required to meet demand without considering what's already on hand. These figures can come from various sources such as:

• Sales forecasts
• Customer orders
• Long-term contracts

This step also involves considering lead times for materials, meaning how long it will take for materials to be produced or delivered.
Recognizing gross requirements helps in preparing and planning for future needs. It's the starting point from which all additional calculations will occur. By identifying these needs early, businesses can better manage their supply chains and avoid potential shortfalls.

Net requirements are derived from gross requirements but show a more practical view of what truly needs to be procured or produced. To find net requirements, you need to undergo a process called "Netting."
This involves adjusting gross requirements by subtracting current on-hand inventory and any quantities that are expected from scheduled deliveries or shipments. Here's how to calculate net requirements:

• Start with the gross requirements.
• Subtract the current inventory levels.
• Deduct any incoming supply that is confirmed to be en route.

This method effectively provides a precise quantity of what is still needed. If the resulting calculation is negative or zero, it means the existing and incoming stock is enough to cover the planned demand.
Understanding net requirements is crucial in ensuring that resources are used efficiently without overstocking or understocking.

Safety stock is an essential part of inventory management, acting as a buffer or cushion against unforeseen fluctuations in demand or delays in supply. It's a protective layer to prevent stock-outs and ensure smooth operations.
Calculating an adequate safety stock is critical. To calculate safety stock:

• Consider historical demand variability.
• Think about the variability in lead times, or how long it takes for stock to be replenished.
• Apply a predetermined percentage of average demand as a safety cushion.

For instance, if your historical data shows that demand goes up unexpectedly or that there are often delays in delivery, you'll need a larger safety stock.
This ensures that you have enough products to meet customer needs without delay. Including safety stock in your net requirements helps to provide a better safeguard against inventory shortages, maintaining customer satisfaction and operational continuity.
