Q

What are Quality Characteristics

A

The several elements that jointly describe what the user or
consumer thinks of as quality

17
Q

What is specification?

A

Desired measurements of the
characteristics. The specification of a product
falls between the specification limits

18
Q

What is USL?

A

The largest allowable value for a quality characteristic is called the Upper
Specification Limit (USL)

19
Q

What is LSL?

A

The smallest allowable value for a quality characteristic is called the Lower
Specification Limit (LSL).

20
Q

What is CL?

A

The average value of LSL and USL for a quality characteristic is called the center
line that refers the target value of a product. CL = (USL + LSL)/2

21
Q

What are Non-Conforming Products?

A

The products that fail to meet one or more of its
specifications is known as nonconforming products. Nonconforming product is called
defective as it has one or more defects.

22
Q

What is a defect?

A

: A defect is a nonconformance to the specification.

23
Q

What are the 5 M’s and 1E of Fishbone Diagrams?

A

Man, Machines, Methods,
Measurements, Material and Environment.

24
Q

What is FMEA?

A

FMEA can be explained as a group of activities intended to
Recognize and evaluate potential failures.
Identify actions that could eliminate or reduce them.
Document the process.

25
Q

Benefits of FMEA

A

Improve the quality, reliability and safety of a product or a process.
 Improve company image and competitiveness.
 Reduce system development time and cost.
 Collect necessary information to reduce future failures, capture engineering
knowledge.
 Reduce the potential for warranty concerns.
 Reduce the possibility of the same kind of failure in the future.

26
Q

What are the two types of FMEA?

A

Design Failure Mode and Effect Analysis
Process Failure Mode and Effect Analysis

27
Q

What is ISO 9000 QMS

A

The international Organization of Standards quality management System

28
Q

What is the Taguchi Method?

A

The Taguchi method is a statistical method developed by Taguchi and Konishi.
Initially, it was developed for improving the quality of goods manufactured, later it
was expanded to many other fields.

29
Q

What is the Taguchi two-step process

A
  1. Make the product/process perform in the best manner most of the time (less
    deviation from the target).
  2. Make all products perform as identically as possible (less variation between the
    products).
