Question No: 22 ( M a r k s: 2 )

Why prototypes are used?

Answer:

In many fields, there is great uncertainty as to whether a new design will actually do what is desired. New designs often have unexpected problems. A prototype is built to test the function of the new design before starting production of a product. Building the full design is often expensive and can be time-consuming. A prototype allows manufacturers to rapidly and inexpensively test the parts of the design that are most likely to have problems, solve those problems, and then build the full design.

Question No: 25 ( M a r k s: 5 )

Discuss different types of problems we faced in decision making process?

 

Answer:

 

Types of Problems

Nature of problem determines the approach to decision making to be followed to solve it. There are three broad categories.

• Structured: Well-structured problems are constrained problems with convergent solutions that engage the application of a limited number of rules and principles within well-defined parameters.

• Unstructured: Problems possess multiple solutions, solution paths, fewer parameters which are less manipulate able, and contain uncertainty about which concepts, rules, and principles are necessary for the solution or how they are organized and which solution is best.

• Semi-structured – a gray area lies between the structured and unstructured range. Here part of the decision can be specified allowing for certain factors out of control.
