Design of Goods and Services
Explicit documentation accomplishes two things:
(a) it provides the information necessary to produce the
product in the appropriate fashion
(b) if the product we produce does not perform as we
anticipated, the documentation provides the basis for
finding and correcting the problems in a logical manner.
Product definition includes engineering drawings, written
specifications, bill-of-materials, formulas, portion control
documents, scripts, insurance policies, etc.
Investment, market share, product life cycle, and breadth of
the product line are all linked to the product decision.
Once a manufactured product is defined, the documents used
Time-based competition uses a competitive strategy of getting
products to market rapidly and may include rapid design, efficient
delivery systems, and JIT manufacturing.
Joint ventures are combined ownership between two firms to
form a new entity with a new mission. Alliances are cooperative
agreements that allow firms to remain independent, but use
complementing strengths to pursue strategies that support their
organization; Traditional—different phases of development done
in distinct departments; Champion (or Product Manager)—a
manager shepherds the product through the development process;
Teams—product development teams, design for manufacturability
teams, value engineering teams. This last version seems to work
best in the West.
Robust design means the product is designed so that small
variations in production or assembly do not adversely affect the
CAD benefits: maintain various kinds of engineering
standards; check interference on parts that must fit together; and
efficiently analyze existing and new designs for technical
attributes such as strength, stress, and heat transfer.
A bill of materials lists the components, their description,
and the quantity of each required to make one unit of the product.
An engineering drawing shows the dimensions, tolerances,
materials, and finishes of a component.
An assembly chart shows in schematic form how a product
is assembled. Along with a list of the operations necessary to
produce a component, the process sheet includes specific methods
of operation and labor standards.
The moment-of-truth is the moment that exemplifies,
detracts from, or enhances the customer’s expectations.
House of Quality is a rigorous method aimed at that specific
result. It identifies customer wants, and relates them to product
attributes and firm abilities. It orders the wants and measures the
strength of the links between wants and attributes.
