SIX SIGMA

Failure Mode & Effect Analysis involves what activity?

 The determination of the probability of failure in a specified period of time
 The expected number of failure in a given time interval
 The study of how a product fails and what causes the failure
 A study of the probability of success in a given time period

The length of Machine Part is known to have a Normal Distribution with a Mean of 100mm and Standard Deviation of 2mm. What Proportion of the Parts will be in between 99.5 and 102.5mm?

 0.0850
 0.0495
 0.0401
 0.42

In a SIPOC Analysis, Outputs include?

 Results; Value-added Products or Services.
 Results; Value-added Products or Services, resources.
 Results; Value-added Products /Services, Payments, Documentation, Input to other Processes
 Data

The Kano Model is interpreted as Follows?

 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 wants can be determined once and for all and used to design high-quality Products and Services.
 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.

 Run Chart
 Control Chart
 Pareto Chart
 Scatter Diagram

What is the relationship between Bias & Linearity?

 None of the Options.
 Linearity is a special case of Bias
