Inprocess Quality Engineer Interview Questions and Answers for Freshers

Process capability formula determines if a process is capable of producing products within specifications.

• Process capability formula compares the process variability to the product specifications.

• The formula is expressed as Cp = (USL - LSL) / (6 * standard deviation).

• A Cp value of 1 indicates that the process is capable of producing products within specifications.

• A Cp value greater than 1 indicates that the process has potential for improvement.

• A Cp value less than 1 indicate...read more

Cp is a process capability index that measures the potential of a process to meet specifications, while Cpk measures the actual performance of the process.

• Cp measures the spread of the process data around the target value, while Cpk measures the deviation of the process mean from the target value.

• Cp only considers the upper and lower specification limits, while Cpk considers the mean of the process data as well.

• Cp should be greater than or equal to 1 for a capable process, wh...read more
