Answer:

Both parts A and B of the statement are True

Explanation:

Six Sigma

Explanation:

Six Sigma is a quality business management strategy which helps business organizations to improve the quality of processes, products and services by discovering and eliminating defects, variations or errors. It is a strategic business concept that was developed in 1986 by Motorola.

Under the six sigma approach, any process that doesn't provide customer satisfaction or causes challenges in an organisation's process should be eliminated from the system in order to produce quality products and services. It allows only 3.4 defective features for every million opportunities and as such expects processes to be defect free 99.99966 percent of the time.

1. DMAIC: define, measure, analyze, improve and control. it is a data-driven improvement cycle used for improving processes and driving Six Sigma projects.

2. DMADV: define, measure, analyze, design and verify.

Also, the Six Sigma approach to quality control avails businesses the ability to detect potential problems early, so as to prevent their occurrence.
