OPERATIONS MANAGEMENT EXAM #23 QUESTIONS AND ANSWERSGlobal teams provide diversity while eliminating conflicts and miscommunication. - correct answer FALSE Using globally diverse design teams increases the risks of conflicts and miscommunication.
A 'House of Quality' is achieved when no department in a single location has more than 15% rejects. - correct answer FALSE The house of quality is a means of integrating the voice of the customer into the product
or service development process.
Concurrent Engineering is another term for sequential development. - correct answer FALSE Concurrent engineering involves simultaneous product and production development.
One of the main advantages of standardization is that it increases the potential variety of products - correct answer FALSE Standardization reduces the variety of products.
A disadvantage of standardization is the possibility of standardizing designs too early, which may make it difficult to modify in the future. - correct answer TRUE Standardization locks firms into designs that aren't easily changed.
Reducing consumer choices makes service more efficient. - correct answer TRUE Efficiency comes from the standardization that results from reduced consumer choices.
Modular design increases costs of purchasing and controlling inventory compared to non-modular. - correct answer FALSE Modular designs make inventory management easier and cheaper.
Product failures can be easier to remedy with modular design. - correct answer TRUE Modular designs make it easy to change only portions of the design.
One motivation for an organization to redesign its product or service is to avoid the alternative of downsizing the organization. - correct answer TRUE The threat of downsizing often spurs product or service redesign.
A major benefit of Computer Aided Design (CAD) is the increased productivity of designers. - correct answer TRUE CAD tends to greatly increase designers' productivity.
Most of the time what is called product or service design is actually a redesign of an existing product or service. - correct answer TRUE Usually the core product or service remains relatively unchanged even though other features are modified or enhanced. A service blueprint is quite similar to an architectural drawing. - correct answer TRUE A service blueprint shows the basic customer and service actions involved in a service operation.
The process of dismantling and inspecting a competitor's product to discover product improvement is called benchmarking. - correct answer FALSE Dismantling and inspecting a competitor's product to discover product improvement is called reverse engineering.
To save money, it is essential that designers revise the production capabilities to meet the requirements of the new products. - correct answer FALSE Saving money requires designers to ensure that new products can be produced using existing production capabilities.
Many US manufacturers are now shifting their focus from products to both product and process improvements. - correct answer TRUE Both product and process must be considered in the product/service design question.
Applied research has the objective of achieving commercial applications for new ideas. -
correct answer TRUE Applied research is aimed at commercializing basic research.
Basic research is done with the expectation that discoveries will have near-term commercial application - correct answer FALSE Basic research is done with no clear expectations regarding commercial application.
"Design for production" takes into account the capabilities of the organization to produce
or deliver a given product or service. - correct answer TRUE Design for production is important to ensure that product or service design decisions are
feasible.
Consumers tend to resist purchasing products containing recycled materials. - correct answer FALSE Consumers are beginning to respond positively when informed that their purchases contain recycled materials.
"Concurrent engineering" brings people concerned with manufacturing into the design phase earlier than in the "over-the-wall" approach. - correct answer TRUE Concurrent engineering people concerned with manufacturing are actively engaged in the design phase.
"Concurrent engineering" means that at least two engineers are involved in product design at the same time. - correct answer FALSE Concurrent engineering means that engineers, marketing, manufacturing and purchasing personnel often are jointly involved in the product design. One approach to extending a product's life cycle is to promote alternate uses of the product. - correct answer TRUE Alternate uses extend product life cycles.
"Quality Function Deployment" is a structured approach that guarantees that the highest
quality product or service will be designed. - correct answer FALSE Quality Function Deployment ensures that the voice of the customer is integrated into the product or service design question.
Product liability means that a manufacturer is liable for any injuries and damages caused by a faulty product because of poor workmanship or design. - correct answer TRUE Product liability is a serious issue for manufacturers.
The process of dismantling and inspecting a competitor's product to discover improvement is called reverse engineering. - correct answer TRUE Reverse engineering is a legitimate means of evaluating the competitive landscape.
Research and development (R&D) refers to organized efforts that are directed toward increasing scientific knowledge and product (or process) innovation. - correct answer TRUE Product or process innovations often result from deliberate R&D programs.
Standardization refers to the extent to which there is absence of variety in a product, service, or process. - correct answer TRUE Standardization reduces variety and leads to greater efficiency.
Re-manufacturing refers to removing some of the components of old products and reusing them in new products. - correct answer TRUE Re-manufacturing is a way of increasing sustainability.
The demand for a product and the rate of technological change have significant impact on the length of a given phase of the product life cycle. - correct answer TRUE How long a product stays in a particular phase of its life cycle depends greatly on the rate of technological change.
Robust design describes a product that will perform satisfactorily so long as it is used in a very narrow range of conditions. - correct answer FALSE Robust designs perform satisfactorily across a wide range of conditions.
Taguchi design methods involve identifying the optimal operating or environmental conditions for a given product. - correct answer FALSE Taguchi design methods involve designing products that are relatively insensitive to environmental factors. Quality function deployment (QFD) is based on a set of standards which relate customer requirements to company capabilities. - correct answer FALSE QFD relates customer requirements to product designs and the capabilities necessary to carry these designs out.
The quality function deployment (QFD) matrices are often referred to as the "House of Quality" because, when completed, they "house" all of the customer's quality requirements. - correct answer FALSE QFD matrices link customer requirements with other product/process design elements.
Service design often must take into account the degree of customer contact required. - correct answer TRUE Customer contact is a critical service design issue.
Reliability refers to the ability of a product to perform its intended function under normal conditions. - correct answer TRUE Greater reliability translates into a greater likelihood of the product working in normal conditions.
Applied research is the major R & D effort of business organizations because of the desire for commercial applications. - correct answer TRUE Most business organizations focus on applied rather than basic research.
Commonality of components is beneficial for manufacturing but not for services. - correct answer FALSE Services can benefit from commonality in service elements.
Standardization can at times lead to serious difficulties and competitive struggles, particularly when systems are running under different conditions. - correct answer FALSE It is the lack of standardization that can at times lead to serious difficulties and competitive struggles.
The term failure as applied to reliability means that a part or item does not function at all. - correct answer FALSE Failure means that the part or item does not function as it should.
Reliability can be defined in terms of a particular point in time or in terms of length of service. - correct answer TRUE Reliable designs can be counted on to work over time.
Reliability can be improved by the use of backup components. - correct answer TRUE Adding a backup component is often cheaper than increasing the reliability of a given component.
