Context, analytics, and planning are necessary for a successful inventory plan. Data from business history, sales order, competitor landscape, present social and political events all are necessary for the inventory planning process.
The inventory planning process involves the following steps-
- Gathering the necessary business data including competitor's details.
- Understanding the performance of stock-keeping units and using them to set upcoming expectations.
- Setting flexible budget according to product category.
- Check weekly reports to determine performance and forecast demand periodically.
- Use monthly sales forecast to manage consistent inventory
- Analyze the performance at the end of the season and make necessary changes for the next season's inventory planning.
Inventory planning systems are unique to the type of a business and its needs. Any small business dealing in raw material, partially completed goods, or finished goods must select the inventory planning model that meets all its requirements.
Just in time inventory model- The time inventory model or time jit inventory planning synchronizes the orders of raw materials from suppliers with the production planning schedule. This planning model requires accurate demand forecasting to ensure the availability of sufficient inventory and meet the maximum demand. The time jit method increases efficiency and decreases wastage as businesses use inventory as soon as it arrives.
Deterministic inventory model- Applicable for any small business dealing in raw materials, the deterministic inventory planning model uses a precautionary method to avoid a shortage of inventory items. The economic order quantity is an example of the deterministic inventory model. The economic order model refers to the ideal order quantity that any business should purchase for minimizing its inventory costs. The EOQ model ensures the right amount of inventory is ordered so that there is no excess inventory. The economic order quantity is effective when the demand is steady. However, the order quantity EOQ model is not suitable for seasonal changes in demand. For a successful quantity, EOQinventory planning model businesses have to monitor it constantly.
Work in progress model- This inventory management method is suitable for businesses dealing with partially completed or finished goods and goods in transit. This model prioritizes holding inventory for protecting against demand uncertainties and alleviating the price increase of raw materials or labor.
Perpetual Inventory planning model- This continuous inventory model is preferred by businesses dealing with finished goods. This inventory system tracks the inventory quantities and sends orders to replenish the inventory when the amount reaches the reorder points to maintain safety stock. This inventory planning model requires inventory management software to keep track of current stock levels and avoid any shortage.
