Technically the meaning of quality is simple. Quality is meeting specification. For an object this may mean meeting the size as specified on a drawing. A good example of this could be a 1- cup, measuring cup. A drawing of the cup would include dimensions of the cup such as height, diameter and wall thickness. And with each of the measurements there would be a tolerance. The question is why a tolerance? Why should we have specifications in the first place?

First off, nothing is perfect. There are variations in every thing we do and make. Think about the situation where you are diving on a highway. The speed specification for this example is 60 miles per hour. How simple is it to keep to the 60-mph speed limit? What you find is some drivers are driving less than the speed limit and some are driving over the speed limit. Actually not everyone is driving at the same speed. Now this can get very complicated because we could start talking about the precision of speed measurement, the calibration of the speed odometer, and terrain of the road as a few examples of causes for variation. The real issue is how far from 60-mph can you go before the police will issue a ticket for not following the speed limit. So the ability of a driver to stay within a speed limit means their quality of driving is acceptable or not. That is the driver is meeting specifications of the road.

Here we come full circle. The definition of quality is simple. The problem often is determining what the specification is. Nowhere are there any specification limits that tell us at what speed (over the speed limit) you can go before a ticket is issued. In other issue such a customer satisfaction this can get even fuzzier.

The objective of this bog is to talk about quality in a way range of what quality is now understood to comprehend. I like anyone look forward to talking about this and get some feedback.
