Quality assurance article should be better

As an article on quality assurance, this article should be a lot better. There are quite a few clumsy sentences here, for example, in the first lines "When the first specialized craftsmen arose manufacturing tools for others..." which is not a proper English sentence. Beyond this, there should be a more systematic, detailed and well cited historical overview. At the moment it is a bit shabby. So perhaps here would be a good place to start practicing quality assurance. —Preceding unsigned comment added by 86.24.113.27 (talk) 12:22, 25 August 2008 (UTC)

Yes, the article is not very good. In my opinion it is not very easy to understand and does not address one of the main issues, the difference between QA and QC. In fact, in some places the article is confusing both. I do not have time for a complete review, but I would suggest to remark that QA is related to processes (i.e. ensure that a process to attain quality is followed) while QC is related to products (i.e. ensure that a product has attained the required quality by measurement of specified attributes). QC ensures quality, and QA cannot, but QA is usually a lot cheaper because it helps to avoid early deviations that would lead to bad products - that is, QA can improve the average quality of the products, and can also reduce the QC costs (e.g. sampling frequency and sample size could be reduced). Typical QA activities are process audits - to ensure that the proper process is followed and the required outputs are produced at each stage; typical QC activities are componente and product testing.
