Question

Which of the following statements about six sigma is true?

A. The system was developed at Ford during the 1970s.

B. The lower the sigma number, the lower the level of defects.

C. It is designed merely to reduce product defects.

D. It indicates how often defects in a process are likely to occur.

E. Six sigma always improves the bottom line.

Answer 1

The true statement about Six Sigma is D, indicating how often defects in a process are likely to occur. It's a methodology developed by Motorola to improve business processes, not just for reducing product defects, and it was not developed at Ford.

Step-by-step explanation:

Among the statements about Six Sigma, the true one is: D. It indicates how often defects in a process are likely to occur. Six Sigma is a set of techniques and tools for process improvement developed by Motorola in 1986. It seeks to improve the quality of process outputs by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. Its approach uses empirical and statistical quality management methods and relies on a team of experts with special qualifications.

The statement A is false because Six Sigma was developed at Motorola, not Ford. Statement B is misleading since a higher sigma level indicates fewer defects. Statement C is partially true; while Six Sigma is designed to reduce defects, it is not merely for that purpose but also to improve overall business processes and efficiency. Statement E is not always true; while Six Sigma aims to improve the bottom line, the results can vary based on implementation and other factors.
