A customer does not necessarily want the highest level of performance along all dimensions of customer service, including response time, product variety, product availability, customer experience, order visibility, and returnability.

True

A firm gains the most by outsourcing to a third party if its needs are small, highly uncertain, and shared by other firms sourcing from the same third party.

True

A fundamental aspect of successful collaboration is the identification and resolution of exceptions. Exceptions refer to a gap between forecasts made by the two sides or some other performance metric that is falling or is likely to fall outside acceptable bounds. It is important to have a process in place that allows the two parties to resolve exceptions.

True

A planning horizon is usually between three and eighteen months for an aggregate plan.

A poor aggregate plan may result in a large amount of excess inventory and capacity, thereby raising costs.

True

A process is a series of steps undertaken to achieve a desired outcome or goal.

True

A third party may be able to provide a sustainable growth of surplus by aggregating to a higher level than the firm itself. The growth in surplus comes from aggregating capacity, inventory, inbound/outbound transportation, warehousing, procurement, information, receivables, or relationships to a level that the firm cannot achieve on its own.

True

Short-term forecasts are usually more accurate than long-term forecasts.

True

Supplier performance should be compared based on the impact on total cost of ownership. In addition to acquisition costs, ownership and post-ownership costs should also be considered.

workforce

Seven-Eleven's supply chain strategy in Japan can be described as attempting to micro-match supply and demand using rapid replenishment. What has Seven-Eleven Japan done to develop capabilities that support its supply chain strategy?

- Their facility location choices are to saturate an area with stores, thereby making it easy for customers to shop and their own delivery trucks to move from store to store to replenish inventory. - Their inventory system is run on an information system that transmits directly to the supplier and distribution center; goods are produced using a pull system to replace what has been sold during that delivery period. - Their transportation system is flexible to maximize responsiveness while also achieving efficiency. - Their suppliers are required to deliver to a distribution center where products are sorted by temperature.

Rationing schemes that allocate limited production in proportion to the orders placed by retailers:

- result in a game in which retailers try to increase the size of their orders to increase the amount supplied to them. - lead to a magnification of the bullwhip effect. - lead to the manufacturer being left with a surplus of product and capacity.
