SIX SIGMA

A type of Line graph used to assess the Stability of a Process is called?

 Scatter Diagram
 Run Chart
 Control Chart
 Pareto Chart

The Central Limit Theorem states that the distribution of Sample Means approximates a Normal Distribution if;

 The Sample is randomly Selected
 The Population is Normally Distributed
 The Sample Size is sufficiently Large.
 The Sample is Normally Distributed

In a Process FMEA, Process and/or Design changes can?

 Increase the Probability of Detection.
 Reduce the Probability of Occurrence
 All the Options.

In Project Charter, the actual measure of the Defect or Error in the Process is?

 Problem Statement
 Secondary Metric
 Business Case

Why do we need Control Plan? Answer is/are?

 It helps to produce Consistent and Predictable Quality.
 All the Options.
 It helps new people to understand the Process and its Control Steps.
 It communicates what do we have to Check and Control throughout the Process.

What is the relationship between Bias & Linearity?

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

In a SIPOC Analysis, Outputs include?

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

 Results; Value-added Products or Services.

The Number of employees at five different superstores are 3, 5, 6, 4, and 6. Treating the Data as a Population, find the Mean Number of Employees for the 5 Stores:

 3
 2
 3.8
 4.8

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.
 Customers will be satisfied if you supply them with Products and Services that meet their needs at a fair price.
 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
