Throughout all of industry, one constant significant element exists for companies to ponder over, and that is the act of making sure that each and every item of note is done or produced according to a specific and rigid standard that has been predefined. This is the act of quality assurance. In terms of the successful management of projects, quality assurance is quite significant. Performing quality assurance (which is also known by the two letter anagram QA), is an essential par of the project management process.
