Description
This MBA style course prepares and empowers you to calculate and control your Safety Stock. A crucial area of Inventory Management.
The eternal question:How to balance the risk of stock-outs with the quantity of safety stock inventory held?...
We cover3 methods to calculate your Safety Stock- from supersimple to advancedstatistics:
Method 1: Number of Days of Safety - A fast and very basic method to get a quick decision
Method 2: HiHi-AvAv (my own name for a very established method ;) Finding the difference between our high "Lead Time Demand" and the average to determine the level of cover we want from periods of high demand during a slow replenishment lead time.
Method 3: Statistical Method - The most rigorous method. We model our "Lead Time Demand" as a "Normal Distribution", determine our desired "ServiceLevel" (acceptable risk of a stockout) and use a little help from some excel formulas to calculate our required Safety Stock and Re-Order Point quantity.

Almost all businesses have inventory: retail stores, factories, hospitals, hotels, car repair, warehousing, logistics and more - this means we all have to decide how much to hold and when to place an order from the suppliers for more. Place the order too late and, with a little extra demand than usual, you might stockout! Carry too much inventory and you pay for it in holding and financing costs every day, quietly sucking the profit from your business and crippling your cashflow and investment opportunities.
Having enough stock available whilst minimising costs and risk is the fundamental balance that can determine your business's success. Getting a strong control and continuously improving your business operations is essential to remain competitive, improving profitability, improving customer experience and customer satisfaction, reducing costs and improving delivery.
Without a solid grasp of safety stock and methods of calculation; no operations manager, can competently or confidently manage their risk without excessive costs.
Be the one bringing clarity and structure to this most crucial decision!
