Have you ever wondered what is the difference between QA assurance and QC? Both sound pretty important, but what does each actually do? And which one should you be focusing on for your business? Let's find out together!


What is QA and QC?

 

What exactly is QA, and how is it different from QC? To understand that, let’s first skim through some definitions.

QA is defined as a process or set of procedures used to determine whether a product meets specified requirements. This can be done through quality control, which is the inspection of products to ensure they meet certain standards, or quality assurance, which is the creation of processes to prevent defects from happening in the first place.

 

Meanwhile, QC can be defined as the process of verifying whether a product meets quality standards. This is done through inspections, testing, and audits.

 

What Is QA and QC in Software Testing & What Are the Differences

 

What is the difference between QA and QC for software development? Here’s a quick summary.

 

In software testing, QA is focused on the process of ensuring that the software meets the requirements, while QC is focused on catching defects after they’ve been made.

 

QA includes activities like process improvement and quality control, while QC is limited to quality control. This means that QC will test the software to ensure that it meets the requirements, but it will not take steps to improve the process.

 

QA is a proactive process, while QC is a reactive one. This means that QA will try to prevent defects from happening in the first place, while QC will only catch them after they’ve been made.

 

QA can be seen as an umbrella term that includes QC, while QC is a part of QA.

 

So, Which One Should You Focus On?

 

QA and QC are both important, but which one should you focus on? The answer depends on your needs. If you want to prevent defects from happening in the first place, then you should focus on QA. If you want to catch defects after they’ve been made, then you should focus on QC.
