Lets us take a small example of traffic rules, what if one person does not stop at the red light. There could be an accident involving 2 to 3 people. But what if no one stops at the red light, there will be chaos and lot of people will meet with accidents throughout the day.
Similarly if standards are not followed in a factory what will happen? There will be lot of defects. The product quality will be very poor. There will be accidents and lot of wastage due to rejections. However, the most important requirement is the standard. What are the requirements of a standard? A standard should be:
- Clear & precise
