Question

Six sigma based quality improvement concepts are not applicable to .

• A. Banking
• B. Manufacturing
• C. Health
• D. Infrastructure

Hint:

Six Sigma needs repeatable, measurable processes to work well.

Answer 1

The Correct Option is D

This question checks awareness of where Six Sigma, a data driven quality improvement method, is commonly applied.

1. Banking: Banks and financial services firms use Six Sigma to cut errors in processes like loan processing, account opening and transaction handling, so this sector does use the concept.
2. Manufacturing: Six Sigma began in manufacturing at Motorola in the 1980s and remains widely used there to reduce defects on production lines.
3. Health: Hospitals and healthcare providers apply Six Sigma to reduce errors in areas such as medication dispensing, patient wait times and diagnostic accuracy.
4. Infrastructure: Large scale infrastructure and construction projects are driven mainly by civil engineering, project management and regulatory factors rather than the repeatable, measurable process steps that Six Sigma is built around, so it is not a typical application area for this method.

The correct option is Infrastructure, since Six Sigma is a process improvement tool built for high volume, repeatable processes such as those in banking, manufacturing and healthcare, and is not commonly applied to infrastructure projects.

Let's summarize:

• Six Sigma reduces defects and variation in repeatable business processes.
• Banking, manufacturing and health services are classic Six Sigma application areas, while infrastructure is not.

So the answer is Infrastructure, option (d).
