What is quality in quality control?
Defining quality is tough, and it depends on what you are talking about. Quality on this site might have to do with answers that actually address the question and that are accurate. Higher quality would be if the answer was easy to understand and grammatically correct. Higher quality might be if there were links for additional information and the answer was interesting and written in a compelling way. ... In other places quality will be defined differently. If you were manufacturing LEGOs for instance, they would need to be indestructible from normal use, they would need to be uniform sizes, and they would need to fit together snugly without falling apart or being stuck together forever. Basically, quality means being good... and improving quality means making something better than it was before.
