Need for quality assurance

Answer 1

Quality assurance shows up in different ways throughout industry. In aviation every single action that involves safety of flight must be inspected prior to flight by a quality assurance inspector. In food and other production activities samples are collected and tested for quality, safety, even appearance by people away from the actual production. This provides management with information that can improve products, improve production, reduce waste and so on. It also allows management to pinpoint the exact day and time a particular "lot" was produced if a problem shows up later on at the consumer level.

All together quality assurance helps ensure quality products from a manufacturer for the consumer and it enables manufacturing concerns to streamline their activities as well.

Answer 2

For those of us who have made quality our passion and career, the question seems silly. Of course we need quality assurance (QA). I'm still amazed, though, at organizations that undertake large software development projects who either see quality assurance as a nuisance or an afterthought something you tack on at the end.

A product that hasn't been tested may look ok at first glance, but once you start to scrutinize it, you find the issue that should have been filtered out. There are various estimates on the cost of waiting to check for defects and other issues.

The basic idea is that the longer you wait to address the types of issues that quality assurance testing is meant to correct, the more expensive it is to address them. In short, prevent the problem from happening and there's no cost.
