Quality function deployment, Computer aided design & manufacturing, Product Maintainability

The Key terms of this Operation Management chapter include Benefits, Function Deployment, Product Maintainability, Engineering, Robust Design, Development, Market Opportunities, Supplier, Distributor.


Identify the benefits associated with manufacturability and value engineering.

Benefits include immediate cost reduction, reduced product complexity, additional standardization of components, improvement of functional aspects of the product, improved job design and job safety, improved maintainability (serviceability) of the product, and robust design.


What is quality function deployment (QFD)?

QFD refers to both

(1) determining what will satisfy the customer and

(2) translating those customer desires into the target design.


Reducing the complexity of a product and improving a product’s maintainability are activities of:

manufacturability and value engineering.


Which of the following would likely cause a change in market opportunities based upon levels of income and wealth?

economic change

Identify factors that influence new product opportunities.

Understanding the customer, economic change, sociological and demographic change, technological change, political/legal change, and other changes brought about through market practice, professional standards, suppliers, and distributors.


Provide some examples of recent product changes, i.e. new products that are replacing older ones.

The list in the text includes: TV to HDTV, radio to satellite radio, coffee shops to Starbucks lifestyle coffee, traveling circuses to Cirque du Soleil, land lines to cell phones, cell phone to iPhone, Walkman to iPod, and mops to Swiffers.


Aggressive new product development requires that organizations build structures internally that contain what features?

They should have open communication with customers, innovative product development cultures, aggressive R&D, strong leadership, formal incentives, and training.


Total Quality Management (TQM)

Refers to a quality emphasis that encompasses the entire organization, from supplier to customer


Quality loss function (QLF):

identifies all costs connected with poor quality and shows how these costs increase as the product moves away from being exactly what the customer wants. Loss to society = square of the distance from the target value – cost of the deviation at the specification limit.


Target-oriented quality

a philosophy of continuous improvement to bring the product exactly on target.

Quality robust

products that are consistently built to meet customer needs in spite of adverse conditions in the production process; removing the effects is often cheaper than removing the causes and more effective in producing a robust product


Statistical process control (SPC)

process used to monitor standards, make measurements and take corrective action as a product or service is being produced.


Control charts

graphic presentation of process data over time, with predetermined control limits


Attribute inspection

an inspection that classifies items as being either good or defective (not degree of failure)


Variable inspection

classification of inspected items as falling on a continuum scale, such as dimension or strength


Source inspection

controlling or monitoring at the point of production or purchase (source)


Reducing the complexity of a product and improving a product’s maintainability are activities of:
