Articles to grow your career
Whether you have been in the IT world for quite some time or are just kick-starting your career, you have probably come across the terms quality assurance and quality control. Although most people assume that the two terms represent the same thing, the reality is that they are different. Well, read on to discover everything about quality assurance and quality control.
In simple terms, quality in software refers to the application’s ability to meet and exceed users’ requirements and expectations in terms of design, portability, functionality, interface, reliability, security, durability, efficiency, stability, and price.
You already know what quality is, and now is the perfect time to discuss quality assurance. But before we get started, it is paramount to understand the term assurance. Simply put, assurance is a guarantee that the product will meet and exceed users’ expectations and requirements. It seeks to give users confidence that the product will work properly without any hitch.
With that in mind, quality assurance in testing is a procedure that ensures the quality of products launched by the company. For this to happen, quality assurance focuses on the Software Development Lifecycle to ensure the final product is efficient and meets its specifications and requirements. Examples of QA activities include:
Testers must follow a laid-out cycle to save time and avoid mistakes during quality assurance. These steps are collectively called the Deming cycle or PDCA cycle. Discover how to conduct quality assurance like a pro below:
Now, let’s define quality control or QC. Quality control is an engineering procedure that seeks to ensure the quality of the overall product. Unlike quality assurance, quality control only focuses on the outcome and products.
Quality control allows testers and developers to identify quality issues before launching the product. These issues must be fixed before the product is released. Besides the software quality, QC also seeks to ensure that testers and developers have the required skills to conduct quality control. Examples of quality control activities include:
Even though QC and QA are used interchangeably, they are pretty different. For instance, QA focuses on the quality of specific processes, whereas QC focuses on the entire product. Discover critical differences between the two below:
