9 Inventory Management Ordering Process –ABC inventory method (Manual) –Perpetual inventory (Automated)

10 ABC Inventory Method Classifies inventory items to determine level of control needed Rank items by annual purchases cost A = 70% (10% of all products) - tight control B = 20% (20% of all products) - mod. control C = 10% (70% of all products) - least control

11 Inventory Cost Ordering Cost: The costs of placing and receiving and order. Examples: clerical costs and documents Carrying Costs: The costs of keeping inventory. Examples: space costs, expiration, damage, shrinkage Out of Stock Costs: The cost of not having sufficient inventory. Examples: Cost of expediting, taxi, cost of alternate therapy

12 Safety Stock Variability of demand Lead time (Delivery Schedule) Importance of therapy

13 Demand Forecasting Demand Forecasting – Weighting factors are applied to past purchases to calculate trends. Reorder Point (ROP) = Safety Stock Reorder Quantity (ROQ) = Economic Order Quantity

14 12-14 The Inventory Cycle Profile of Inventory Level Over Time Quantity on hand Q Receive order Place order Receive order Place order Receive order Lead time Reorder Point or Safety Stock (ROP) Usage rate Time Reorder Quantity (ROQ)

15 Ordering Intervals A items will be inventoried and ordered a minimum of 2 times weekly. B items will be inventoried and ordered a minimum of weekly. C items will be inventoried and ordered once every 14 days. Do no overlook efficiencies from being organized.

16 McKesson Inventory Management Shelf Tag System A, B, C items are identified based on your ordering history (Orange-A, Blue-B, Yellow-C) ROP (Reorder Point) ROQ (Reorder Quantity) System also calculates ROP and ROQ based on your ordering history

17 Mean Absolute Deviation Percentage Mean Absolute Deviation Percentage (MADP) can be used as an indication of the accuracy. Range of MADP Very reliable Reliable Irregular but useful >0.76 Unreliable due to variance in purchases Facilities should look for products that have a MADP under 0.5 and a low turn. These would be prime suspects for improvement. * Found in 12 month Inventory Turns Forecast Report Detailed

18 18 Inventory Turn 18 Measured by dividing total cost of products purchased by inventory value. Lower inventory turnover is a sign of inefficiency and inflexibility. Upward trends in inventory turnover can be indicative improved inventory management.
