If you are in this category, we assure you that you will become a changed person after reading this piece. So, join us as we embark on this engaging, informative journey. First and foremost, we will start with the definition of both terms.    

Definition of Quality Control

This is a corrective procedure that ensure that a fresh-out-of-the-factory product meets established standard by comparing the sample against certain specifications. With an acronym QC, Quality Control is commonly used in industries where new product or service is always churned out every now and then. Before the organization approves that the product or service can be launched into the market, it will be tested against certain standards to ensure that it adheres to, or meet the requirements of the end-user.

In other words, companies have to comply with the directive of a regulatory body that ensures that products on the market are fit for use or consumption. It should be noted that QC is a set of procedures that focus on the goods or services. Basically, these procedures define the requirements expected of the product/service. In a nutshell, emphasis is on goods and services here.

Well, people don’t seem to grasp the disparity between quality assurance and quality control. Just before we go into that, it is critical that we define the former.

Definition of Quality Assurance

This is a systematic method of ascertaining whether a procedure meets the required standard or not. No doubt, this term shares lots of similarities with the previous one, but not without some contrasts. Also denoted QA, Quality Assurance defines the requirements for developing products and services that are fit for human consumption. The aim of this method is to build customer loyalty by improving the production process and efficiency of a company.

For companies to supply products and services that go beyond their geographic borders, they are mandated to meet ISO 9000, which is also known as Quality Management System. When enlightened consumers see the seal of the international regulator, ISO, on the product that they are about to purchase, it gives them the confidence that the product is fit for human consumption.

Although the practice of using QA originally started in the manufacturing industry, the SaaS industry has already embraced it. Today, software is expected to meet certain specification for a purchaser to have the confidence in it. Ideally, in this concept, focus is on the system that produced the goods or services

What is the difference between quality assurance and quality control? We bet you’re still going to find that question a bit difficult to answer, aren’t you? We will soon present you with a table that will enable you to brilliantly explain quality assurance vs quality control.
