What is Quality of a product and What is the necessity of Quality Product

What is Quality.....

The first question comes in mind when we talk about the Quality Assurance/Control is 'What is Quality"?????? 

In my journey of being a part of the global Quality Assurance Community, i have learnt the various definitions of the "Quality"...Some of them can be shared as below:

"Quality is fitness for use" said by Juran

" The totality of features and characteristics of a product or services that can bear on its ability to satisfy stated or implied needs"..ISO 9000 definition

"Quality is the realistic property of a product which comply to specifications and the lead to customer satisfaction" that what i believe in......

Next point is Why quality requires????? Why a company requires to maintain the product quality??????? 

Reasons:

a) To be profitable

b) To reinforce personnnel quality standrad

c) To maintain customer satisfaction

d) To increase productivity

e) To increase competitiveness

f) To lower cost 

Phases of Quality Revolution:

The Quality Control has been gone through various revolution stages in the last century, these can be categorised as follows:

1) Operator Inspection

2) Foreman Verification

3) 100% Inspection

4) Statistical Sampling Inspection (SQC)

5) Statistical Process Control (SPC)

6) Total Quality Control (TQC) Statistical Prob. Solving (SPS)
