POM 58 Test 1 Quiz Questions
Can a production process be labeled as "out of control" because it is too good? Explain. - ✔ ✔ Yes. If
all other samples are not consistent with the desired results, but only few are, then the few could be
considered outliers.
Define "in statistical control." - ✔ ✔ A process can be considered in statistical control when there are
no remaining special causes of variation, only natural or common causes of variation are present.
Describe four organizational approaches to product develop-ment. Which of these is generally thought
to be best? - ✔ ✔ 1. US approach that divides an organization into different parts. Firms can be
divided into departments such as research & development, engineering, manufacturing, and production.
The main advantage of this approach is that each department has fixed responsibilities to uphold, while
the main disadvantage is lack of forward thinking.
2. assigns a product manager to divide up work between departments and organizations. The manager
acts as the central means of communication between each department and accepts the main
responsibility of making sure the product gets finished.
3. use of teams. Teams are often comprised of people from different departments who bring certain
skills and knowledge from their respective areas. Together, this team will bring the product from market
requirements to product success. This is often referred to as the best method of product development. -
best approach
4. bypasses the issue of dividing a product management into departments, but instead focuses on the
organization as one unit. This reflects traditional Japanese values, as they often emphasize teamwork
and shared responsibility more than many Western countries
Describe how an organization's mission and strategy have different purposes. - ✔ ✔ The mission is
the organization's purpose explaining hw it will contribute to society. Strategy is the organization's
action plan to achieve the mission.
Discuss the advisability of using modular assemblies in manufacturing. (What are the advantages and
disadvantages?) To what extent can these arguments be applied to service products? - ✔ ✔ modular
designs offer flexibility to both production and marketing. Makes changes easier because parts and
components are subdivided into modules that are easily interchanged.
modular services allow you to mix and match the kinds of services you desire.
Disadvantages of modular assemblies are that modules are more expensive than product-specific
Verizon since it must function for multiple products.
, Discuss the managerial issues regarding the use of control charts. - ✔ ✔ 1. First, managers must
select the points in their process that need SPC. They may ask "Which parts of the job are critical to
success?" or "Which parts of the job have a tendency to become out of control?"
2. Second, managers need to decide if variable charts (i.e., x and R ) or attribute charts (i.e., p and c) are
appropriate. Variable charts monitor weights or dimensions. Attribute charts are more of a "yes-no" or
"go-no go" gauge and tend to be less costly to implement.
3. Third, the company must set clear and specific SPC policies for employees to follow. For example,
should the data-entry process be halted if a trend is appearing in percent defective records being keyed?
Should an assembly line be stopped if the average length of five successive samples is above the
centerline?
Explain briefly what an x bar - chart and an R - chart do. - ✔ ✔ X bar chart - a quality control chart for
variables, indicates when changes occur in the central tendency of a production process
R Chart - A control chart that tracks the range within a sample; it indicates that a gain or loss in
uniformity has occurred in dispersion of a production process
Explain how improving quality can lead to reduced costs. - ✔ ✔ When quality improves this can lead
to greater demand, greater market share, and greater economies of scale. With high quality things such
as less scrap, rework, and lower warranty costs are found with it, which leads to less inputs costs for the
same amount of output. With improved quality comes improved productivity.
Explain how just-in-time processes relate to the quality of an organization's outputs. - ✔ ✔ 1. cuts
the cost of quality- less inventory means less costs. inventory hides bad quality, whereas JIT exposes bad
quality
2. improves quality - shrinks lead time, limits number of potential errors.
3. better quality means less inventory and a better, easier to employ JIT system. allows firms to reduce
costs associated with inventory
Explain the difference between value analysis and value engineering. - ✔ ✔ -value engineering are
activities that help improve a product's design, production, maintainability, and use.
-Value analysis reviews successful products during the production process and improves them so they
will have a benefit economically and environmentally.
Explain what is meant in service design by the "moment of truth." - ✔ ✔ The moment of truth is
when the relationship between the provider and the customer is crucial. At that moment, the
customer's satisfaction with the service is defined. It is the moment that exemplifies , enhances, or
detracts, from the
