values grater than 1 SD above the mean.a. 32

b. 36

c. 50

d. More then 50

e. The percentage of observations covered by mean +/- 1 SD is 66.6%,

3. A normal distribution is represented by ‘ the process mean’ and----variance-----------------

4. The defect level in a process without ‘mean shifted’ for 6 sigma level operation is

--------------------------------5. The defect level in a process with ‘mean shifted’ for 6 sigma level operation is

--------------------------------

6. When the mean shifted,

a. It increases the defect levelb. It reduces the defect level.

c. Can be anything, depending upon the situation7. How much “shifting of mean” is allowed, while doing six sigma calculation and

data processing ?

a. + 1.57 SD

b. +1.0 SDc. + 2.0

d. + 1.5 SD

e. Depends on the particular process for which calculation is being done8. Define the process capability Index

the process capability index or process capability ratio is a statistical measure of

process capability: The ability of a process to produce output within engineering

tolerances and specification limits.

9. What is the difference of Cp and Cpk?

Cp Estimates what the process would be capable of producing if the process could becentered.

Cpk Estimates what the process is capable of producing if the process target is

centered between the specification limits.

Fmea- failure mode and effect analysis.

It identifies the cause of failure mode and traces it forward to its effect.It is a bottom up approach.

A Failure mode and effects analysis (FMEA) is a procedure for analysis of potential

failure modes within a system for the classification by severity or determination of thefailure's effect upon the system. It is widely used in the manufacturing industries in

various phases of the product life cycle

5 Basic types of Check Sheets :

• Classification : A trait such as a defect or failure mode must be classified into acategory.

• Location : The physical location of a trait is indicated on a picture of a part or

item being evaluated.

• Frequency : The presence or absence of a trait or combination of traits is

indicated. Also number of occurrences of a trait on a part can be indicated.

• Measurement Scale : A measurement scale is divided into intervals, andmeasurements are indicated by checking an appropriate interval.

• Check List : The items to be performed for a task are listed so that, as each is

accomplished, it can be indicated as having been completed

http://en.wikipedia.org/wiki/Procedure





An FMEA simple scheme would be to have three indices ranging from 1 (lowest risk) to

10 (highest risk). The overall risk of each failure would then be called Risk PriorityNumber (RPN) and the product of Severity (S ), Occurrence (O), and Detection (D) but

the Detection 1 means the control is absolutely certain to detect the problem and 10means the control is certain not to detect the problem (or no control exists). rankings:RPN = S × O × D. The RPN (ranging from 1 to 1000) is used to prioritize all potentialfailures to decide upon actions leading to reduce the risk, usually by reducing likelihood

of occurrence and improving controls for detecting the failure
