Important Questions and Answers: Total Quality Management Tools and Techniques

1. What is meant by benchmarking?

The process of gathering information about the ‘best quality product manufacturing company ‘ in order to copy , follow and excel, is known as benchmarking.

Benchmarking is defined as a systematic method (or) popular TQM tool by which organizations can measure themselves against the best industry practices.

2. What is meant by quality function deployment (QFD)?

Quality function deployment (QFD) is a TQM tool which ensures that customer’s requirements are met throughout the design process and also in the production systems.

3. Write about House of quality.

The primary planning tool in QFD is the House of Quality. House of Quality is a set of matrix used to translate the voice of the customers into technical design requirement that meet specific target values and characteristics of the final product. Because of its structure, it is referred to as the ‘House of Quality’.

4. Name different loss measurements in TPM?

a. Down time losses – Planned – Unplanned

b. Reduced Speed Losses

c. Poor Quality Losses

5. What is meant by Failure Mode and Effect Analysis (FMEA) ?

Failure Mode and Effect Analysis (FMEA) is an analytical technique which combines the technology and experience of the people

To identify foreseeable failure modes of a product(or) process To plan for its elimination.

6. Define Reliability.

Reliability is defined as the probability of a product performing satisfactorily without failure of a specified function under specified conditions for a specified period of time.

7. What is Debug failure ?

Debug includes a high failure rate at the initial stages because of inappropriate use (or) flaws in the design (or) manufacturing.

8. What are the two important types of FMEA ?

1. Design FMEA

2. Process FMEA

9. What are the three classes of customer needs?

1. Dissatisfiers: are the needs that are expected in a product (or) service

2. Satisfiers: are needs that customers say they want

3. Exciters/Delighters: are new (or) innovative features that customer do not except.

10. Draw the Taguchi Loss Function?

11. What are the three types of benchmarking?

1. Internal benchmarking

2. Competitive benchmarking

3. Process benchmarking.

12.            Name different types of matrix diagrams.

1. L- Matrix

2. T- Matrix

3. Y- Matrix

4. X- Matrix

5. C- Matrix.

13.            What is meant by performance efficiency?

Reduced speed losses are measured by tracking performance efficiency using the Performance efficiency E=(C*N/T)*100

Where C=Cycle time

N= Number of units produced.

14. What are the three main categories of failure?

1. Debug

2. Chance

3. Wear out

15.        What are the six steps in benchmarking process?

•         Deciding what to benchmark

•         Understanding current performance

•         Planning

•         Studying others

•         Learning from the data

•         Using the findings and taking action
