 Both options (A) & (B)
 None of the Options.
 Bias is the Measure of inaccuracy at a point. Linearity is an evaluation of the Bias at several Poin
 Linearity is a special case of Bias

Failure Mode & Effect Analysis involves what activity?

 A study of the probability of success in a given time period
 The determination of the probability of failure in a specified period of time

The Kano Model is interpreted as Follows?

 Customer wants can be determined once and for all and used to design high-quality Products and Services.
 Customer Wants, Needs, and Expectations are dynamic and must be monitored continuously. Providing Products or Services that match the Customer’s Expectations is not enough to assure Customer Satisfaction.
 Customer Satisfaction is determined solely by the quantity of the Product or Service delivered
 Customers will be satisfied if you supply them with Products and Services that meet their needs at a fair price.
