Chapter 6 Managing Inventories
Management Difficulties Hard to measure and value The value may change Subject to fraud Hidden costs Physical count
Fraudulent Inventory Practices Leave higher cost in inventory – sell the cheaper costing product first Damaged goods labeled as work in progress Obsolete inventory kept at full cost Moving inventory and counting twice Contents of boxes mislabeled
Most Inventory Problems Management buys or produces too much of the wrong merchandise at the wrong price. Operations Manager’s Job
The Operation Perspective Production Process Continuous production Raw material is consistent Little work in progress (no inventory) But what happens if demand falls And what happens if demand rises Project production No finished goods Immediate delivery Easily controlled raw materials
The Operation Perspective Job-shop production Product made to order Short production period Assembly Line Production Inventory is based on the product
The Tradeoffs Too much inventory means Funds are tied up Storage expenses Handling expenses Damaged inventory Vulnerable to theft Physical Obsolescence (Spoilage) Economic Obsolescence
Financial Perspective Volatile Demand – Greater loss potential Build to order Divide into components (Integrate) Increase capacity when needed
Financial Perspective Seasonal Demand Give incentives for early sales (Dating) Customer commitment Warehouse filled with your product and not the competitions Less storage for your inventory Less Product handling Better loan credentials
Financial Perspective Stable Demand Even if seasonal can it be predicted and aligned with production Some products can be stored cheaper than offering incentives Increased demand is usually not a serious problem
Financial Perspective Inventory Reduction Sell the inventory Give away inventory for tax benefit Sell inventory at discount Cut production rate for next year
Financial Perspective Building to order or speculation Avoids work in progress Can offer a build and hold plan Watch encumbered accounts Get deposit or letter of intent to purchase Make production timelines from realistic sales estimates
Managerial Decisions Offer build and hold instead of discount Determine how far in advance to produce orders Sell as a pseudoconsignment Managing pipeline inventory Understand the initial stocking of new products
Inventory Valuation Average Cost Method LIFO (Last In First Out) FIFO (First In First Out)
Average Cost Method Seldom Used Total cost of goods in inventory are summed and averaged to give a cost of goods value No real value for this method
FIFO First Inventory purchased is assigned to cost of goods sold More recent purchases are applied to the inventory values Decrease cost of Goods Increase inventory value Increase profit =higher taxes Most accurate for real life experience
LIFO Most recent inventory costs become cost of of goods sold Older purchases are assigned to inventory Higher cost of goods Decrease Inventory value Decrease Profits = lower taxes
