This is mainly because both of them are inter-related aspects of major quality management that ensure that the deliverables are of high-quality, meeting the expectations of customers. That being said, there are a number of distinctive differences between the two that we will delve deep into in a discussion on quality assurance vs quality control.<\/p>\n<p id=\"\">Before moving onto the major differences between quality assurance and quality control, let\u2019s first clearly define the two, according to the guidelines given by the <a id=\"\" href=\"https:\/\/www.iso.org\/iso-9001-quality-management.html\" target=\"_blank\" rel=\"noopener\">International Organization for Standardization<\/a> (ISO 9000).<\/p>\n<p id=\"\">Quality assurance (QA) is a proactive approach aimed at improving processes to prevent defects in products or services.
