Japan had a widely held reputation for shoddy (poor-quality) exports and their goods were shunned (avoided) by international markets. Edward Deming and Joseph Juran practiced the quality of Japanese goods would overtake the quality of goods produced in the US by the mid 1970's because of Japan's revolutionary rate of quality improvement. At first, the US did nothing. Japanese success was price-related. By the 1970's, US Industrial sectors such as automobiles and electronics had been broadsided (criticized or attacked) by Japan's high quality competition. By the end of the 1970's, the American quality crisis reached major proportion.

Be able to define a critical customer and the customer needs assessment of order winners, losers and qualifiers. Be able to determine order winner, loser and qualifier characteristics.

Key/critical customers: A customer that the firm has targeted as being important to its future success. It is important for operations managers to know what product features and delivery terms key customers consider important, what they are willing to pay, and what they consider acceptable. These product-specific traits can be classified into one of three categories: Order winners- Why customers choose your firm? Ex: Better performance or lower price. Order qualifiers- Minimum standards to be met. Ex: Availability, price, or conformance quality. Order losers- Why customers avoid your firm? Poor performance can cause the loss of current or future customers. Ex: When an online retailer fails to deliver an order in a timely manner, a customer might cancel the order and refuse to place orders in the future.

STANDARDIZE- Custom and practice - Standardize the previous four steps into one process and continuously improve it. - Use visual control through performance boards, checklists, and graphs.

Understand the theory of constraints.

The Theory of Constraints (TOC) is the overall management system that strives to improve system performance by identifying, focusing on, and managing constraints (limitation or restriction). The five principles are: - Every process has a constraint - Every process contains variance that consumes capacity - Every process must be managed as a system - Performance measures are crucial to a process's success - Every process must continually improve

What is supply chain management?

What is digital darwinism?

This means that as service levels increase, typically so do costs.

On an exponential smoothing, what is the purpose of the smoothing coefficient?

To indicate the weight given to the most recent demand.

What is the purpose of a control chart?

Why do we use forecast?

To predict future customer demand. It helps plan the system, and plan the use of the system. - What products and services should we offer? - What is the best location? - How should we manage our inventory? - Purchase, production, budgeting and scheduling

What is total landed cost and how is it calculated?

Total landed cost is the sum of all product-related and logistics-related costs.

Know when you would use an X bar and when you would use a R chart.

X bar only averages values. R chart is used to evaluate the gap between the largest and smallest observations in each sample.

What is revenue/yield management?

Yield/Revenue Management: The process that adjusts prices as demand for a service occurs/in response to demand levels. The purpose of it is to shape demand in a way that yields greater revenues or profits. Its goal is to maximize revenue and profit. It also modifies prices to encourage customers to purchase for service at supplier desired times.

In what situations would you use yield/revenue management?

Yield/Revenue Management: The process that adjusts prices as demand for a service occurs/in response to demand levels.
