A. Discover variation relationship for the vital variables and establish operating tolerances on each of the vital variables.
B. Validate measurement system, methods and procedures, establish the current processes capability.
С. Validate the measurement system's ability to produce repetable data; determine the capability of the process to control the vital variables implement stastitical process control on the vital variables.
D. Select the critical-to-quality characteristics and define the required performance standards.
E. Define upper and lower performance limits; identify sources of variation limits: identify sources of variation: screen potential causes of variation to identify the vital variables needing control.
Choose the correct answer from the options given below.
Correct Answer: (d) D, B, E, A, C
Solution:The steps of six sigma process in a sequence are:-
Step-I Select the critical to-quality characteristics and define the required performance standards.
Step-II Validate measurement system, methods and procedures, establish the current processes' capability.
Step-III Define upper and lower performance limits: identify source of variation; screen potential causes of variation to identify the vital variables needing control.
Step-IV Discover variation relationship for the vital variables and establish operating tolerances on each of the vital variables
Step-V validate the measurement system's ability to produce repeatable data: determine the capability of the process to control the vital variables, implement statistical process control on the vital variables.
