Rare, and an organization must have the Aptitude (capability) and Lifespan (sustainability) to
earn appropriate returns on the advantage.

divided by the inputs consumed to achieve those outputs.

o Work In Progress
o Finished Goods
o Replacement Parts Inventory
o Supplies

Finished Goods - Answer✔Items are ready to ship to the customer. No more work is required.
Replacement parts inventory - Answer✔These are maintained to replace other parts in machinery
or equipment as those parts wear out
Supplies - Answer✔Parts or materials are used to support the production process but not usually
a component of the product. These items, such as lubricant and cutting tools, are consumed in the
production process.
Transportation (pipeline): - Answer✔The portion of inventory that is in the process of being
shipped through the distribution system.
4 Types of Demand - Answer✔o Peak
o Seasonal
o Unexpected
o Chase
Peak Demand - Answer✔Demand which occurs in response to planned events such as
advertising, publicity or promotion. The release of a popular game franchise's latest version often
causes peak demand for a few days or weeks.
Seasonal Demand - Answer✔Demand as shoppers adjust their purchase velocity in line with
holidays, especially Christmas. But Halloween, Thanksgiving and even St. Patrick's Day also
create seasonal demand for certain kinds of merchandise.
Unexpected Demand - Answer✔Demand which occurs due to a usually-unexpected event. For
example, an underdog school may upset a favorite during the NCAA's basketball tournament,
causing a run on their merchandise.
Chase Demand - Answer✔Demand that occurs when a company has to adjust production by
rates to match demand by varying the workforce and using overtime. Companies vary the
workforce by adding or reducing the number of employees on duty at any given time. And they
may choose to provide overtime by asking workers to stay on the job beyond their normally
scheduled time.
Safety Stock - Answer✔A cushion of inventory to protect against unexpected demand. In this
way, they can continue to meet customer demand without delays.
Stock Out - Answer✔Occurs when inventory is depleted.
Perpetual Inventory System - Answer✔Continuously monitors inventory levels and is also called
a continuous review system. Requires human input (i.e. cashier) and the ordering of more
inventory is triggered by reorder point.
o Requires an exact inventory balance at all times
o Best for big businesses, retail stores, or banks

o High value and high volume
o Expensive to implement and maintain
Periodic Inventory System - Answer✔Randomly monitors inventory levels and is also called the
fixed order interval system.
o Requires a physical count periodically
o Used when a supplier will only deliver at specific time intervals
o Low value and volume
o Used for small businesses
o Inexpensive to implement and maintain
ABC analysis - Answer✔Has been developed to determine which inventory items should receive
the highest level of control. By multiplying the dollar value of each item by its annual usage, a
dollar usage value can be obtained. Dollar usage follows the Pareto Principle in that frequently,
only 20% of all the items account for 80% of the total dollar usage, while the remaining items
frequently account for only 20% of the dollar usage. This principle leads to the _____
classification, which is based on focusing efforts where the payoff is highest

while the remaining items frequently account for only 20% of the dollar usage. This principle

Economic Order Quantity (EOQ) - Answer✔For inventory that doesn't require production, when
demand is constant and known, when cost per unit does not depend on order quantity.
Most appropriate for retail stores or companies that order finished goods.
Economic Production Quantity (EPQ) - Answer✔For inventory that will be used in production,
When incremental ordering and depletion of inventory is allowed, Also called production order
quantity.
Most appropriate for manufacturing and production companies
The goal of firms using the EOQ & EPQ model - Answer✔Minimize the total annual costs of
ordering and holding inventory by varying the order quantity.
Quantity discount model - Answer✔A discount offered in price for ordering above a specified
amount
Transportation discounts - Answer✔A discount offered on shipping cost for ordering above a
specified amount
