In 2012, the Knight Capital Group, an American financial service firm, was the largest trader in the U.S. Through its Electronic Trading Group, Knight Capital traded more than $21 billion daily. However, this changed in August of 2012 when this leading financial service firm suffered from a loss of $440 million and went bankrupt. What does this have to do with quality assurance vs quality control? Their loss wasn’t random. It was because they skipped the quality assurance and testing process in a hurry. That hurry damaged their firm forever.
Want to learn how to save your business from the same loss and damage? Keep on reading our blog. Here, we’ve explained the key differences, benefits, and best practices to understand quality assurance vs quality control. So, let’s see what they are and why they’re so important.
What is quality assurance?
Quality assurance is what confirms that a product meets quality standards. This is during the product development. It’s a part of the quality management system. These tests also take place after the software development life cycle is complete. Quality assurance ensures that the product develops according to the user’s expectations.
Key principles of Quality assurance
- It focuses on preventing defects. It also finds flaws during and after product development.
- It involves real people testing the product. This ensures that it meets user needs.
- It can be an ongoing and repetitive process. The product should be free from any errors.
- Quality assurance always comes before quality control. QC is the next step after QA.
What is quality control?
Quality control is also a part of the quality management system. Quality control begins after the product development is complete. Here, you conduct many tests to ensure the product is of the highest quality. Unlike quality assurance, it does not go through the quality of the processes. It makes sure that the product’s quality is in good condition. Mainly after it reaches the market.
Key principles of Quality control
- Testing and verification lets quality control detect defects asap.
- It’s high-level procedure. So, quality control finds problems that quality assurance misses.
- It’s a detailed and time-consuming process. It takes time to test the product.
- In Quality control we always execute the program.
Quality assurance vs quality control: What’s the difference?
60% of organizations using automated tests report significant app quality improvements. After all, whether it’s an app or a piece of cloth, one of the first things we notice is the quality. It’s the same thing with quality assurance and quality control. Both sound similar and also have quality in their names. However, their purposes are different. Here are the key differences explained:
Proactive vs reactive
Quality assurance is a proactive process. This means it aims to find issues or bugs before they occur. In quality assurance, we see potential problems that don’t exist yet. The goal is to ensure that the product works fine. It also guarantees that there is no likelihood of errors or malfunctions. This is done through testing and continuous improvement.
Quality control is a reactive process. This means it aims to find defects in the project after they occur. In quality assurance vs quality control, QC reacts to the problems discovered. This could be a bug or malfunction in the software. It involves severe inspections, testing, and analysis to find any product quality flaws.
Process-oriented vs product-oriented
In quality assurance vs quality control, QA is process-oriented. This means that it focuses on preventing quality issues by designing processes. These procedures are designed to improve the software’s quality. They also help prevent quality defects before they even occur. This shows that QA focuses on the software development life cycle process.
Quality control is different; it’s product-oriented. This means that it focuses on finding quality issues in manufactured products. Specifically ones that could affect user satisfaction. Both QA and QC are focused on user expectations and quality standards. But there’s a difference in how they do it. QC focuses on the product more than the process.
System vs parts
Quality Assurance takes a low system-level approach. This helps it focus on the entire process and methods used to produce it. This ensures that all parts of the software development process are optimized for high quality. It looks at how processes are structured. It also looks at how teams work together. This is to see how they achieve quality results from the beginning.
Quality Control focuses on the product’s specific components. It takes a high system-level approach. It deals with inspecting and testing individual items. This is to detect defects or issues that might have occurred during production. QC concerns most with the end result.
Verification vs validation
Quality assurance paves the way for software development. The results we get through QA activities help us create high-quality products. It does so through verification. It verifies the standards of the product’s design and other things.
Quality control paves the way for software launch. The results we get through QC activities help us launch high-quality products. It does so through validation. It validates the product’s efficiency before launch. This also confirms it after development.
The people involved
Quality assurance tends to involve the whole team. It involves the developers, designers, and testers. This is because this step in testing revolves around preventing and improving. Hence why, a broad group of people are involved.
Quality control tends to include specific team members. This is because this step is more significant. The product has already been created. So now all that’s left is testing it finally before launch. This is the step that Knight Capital mainly missed. This caused them their downfall.
Benefits of Quality assurance vs quality control
The businesses that use QA and AC methods experience an average of 9% increase in sales. Additionally, it also causes a 26% increase in profitability. A slight increase in sales is better than none. Let’s see the benefits of quality assurance vs quality control:
