The Business Definition of Quality Assurance
The term Quality Assurance (QA) describes the procedures and processes a business uses to ensure its products and services are of a high standard. Quality assurance aims to detect and correct errors or defects before products are made available to customers.
Process of Quality Assurance
It is not uncommon for the quality assurance process to be complex and lengthy. To simplify the process, it can be integrated with the study Plan-Do-Check-Act model (PDCA), a tool commonly used to manage continuous improvement. The PDCA can be used to map the stages of the Quality Assurance Process:
Step 1: Plan
During this crucial first stage, an expert in quality assurance or manager will set clear goals for producing high-quality goods and recommend suitable processes that can be used to achieve these objectives. This stage allows the company to anticipate any problems.
Step 2: Do
This stage is where the identified processes are implemented. This stage involves the organization's quality plan, which includes training, establishing procedures and quality control.
Step 3: Check
The results are compared with what is expected in Stage 3. The products can then be compared to the standards required. The experts will then move on to the next stage if the products meet the required standards. If they do not, then they return to the initial stage and make any necessary changes.
Step 4: Act
This final phase is when the organization improves the quality individual plan using the information from the previous stage. The organization will make changes to its quality plan and implement new procedures. They will also continue to monitor quality results.
Methods of Quality Assurance
QA methods and tools include techniques and instruments to ensure that services and products meet established standards. We have the following in our list of commonly used methods for quality assurance:
- Identification of processes.
- Auditing for quality.
- Control charts.
- Benchmarking.
- Diagrams of cause and effect.
Six Sigma is another advanced tool. It also includes root cause analysis, the failure mode and effect analysis (six Sigma), and the poka-yoke method.
Identification of Processes
To ensure the team is on the correct path, identifying processes requires defining standards and organizational operations at the start of the project.
Auditing for Quality
A quality audit is an organized method that determines how well the processes and standards perform during the design and development phase. A quality audit could involve reviewing design documents to verify that they meet the project's requirements.
Control Charts
Quality assurance engineers use control charts to assess whether process changes have remained stable. They can predict potential outcomes and determine if a project needs to make changes or fix specific issues. For example, a control chart could be used to monitor the rate of defects in a particular product.
Benchmarking
Benchmarking, a popular tool for quality improvement that uses primary performance metrics to identify the strengths and weaknesses of procedures, is benchmarking. Comparing the performance of an organization with market or industry standards is what benchmarking involves. Benchmarking is also a way to compare current processes with those of competitors or historical data and help quality assurance specialists recommend appropriate actions. A company could benchmark its production processes with competitors to find areas that need improvement.
Diagrams of Cause and Effect
To create cause and effect diagrams, members must brainstorm and list all possible causes for a given problem. They can help identify the root cause of a problem and develop solutions. A cause-and-effect diagram, for example, could be used to determine the factors contributing to a specific defect.

5. A feedback Loop that is Agile and Risk-Based
Around the globe, I've been asked to step in and help turn around struggling businesses. Our experience has shown that a rapid, agile feedback loop based on risk is the best. It allows the organization to identify issues and problems before they escalate, quickly learn from mistakes made and sees them as problems. To avoid problems and issues being hidden, it is essential that the organization's leaders set a positive tone.
6. Tests Based on Behaviour are an Excellent way to Measure the Effectiveness of your Tests
A vital aspect of a quality assurance technology program is creating and automating behavior-driven test cases. The behavior-driven test simulates the way customers use a product. A well-defined series of behavior-driven tests will help detect customer impact before release and avoid costly bug fixes.
7. Use the Ring Method
We use the "ring approach" when we want to test a product before it is released. We send the product to our team after they have had time to fix some bugs. After we have taken their feedback, the product is sent to beta testers for final polish.
8. Ensure that Everyone Participates in the QA Process
Only place part of the responsibility of quality with an independent team. Each engineer in a group of techies should be a quality analyst. Ensure that all team members are creating and testing infrastructure to build quality software.
9. Include QA Tests throughout the Entire Development Process
Realizing that quality assurance only happens as a standalone process once the feature has been built is essential. It should occur at every stage of the development process. The QA process should begin at the feature definition level and continue to the production deployment stage.
10. SDET is a Good Starting Point for your Process
The QA process is one of many things to consider. They are starting with a clean architecture for both the front and back ends. Define the APIs and take an API-first approach. Make sure there are agreed-upon ground rules for your dev team. That should include code checks-in, commit points where developers must submit code that has been tested and test scripts from QA for testing. Therefore, Your processes should be based upon SDET rather than an outdated QA model.
11. Cross-check the Quality with Team Members
Allow the members of your tech team to do each other's QA. They will learn about things developers often overlook and be more aware of them the next time they develop something. You can still have a dev member review the code, even if there is a dedicated QA group. Have the developer sit next to the QA member as they work.
12. Even after the Release, give Your Team Complete Ownership
Allow the squad or team to take full ownership, even after the product's release. The team will be motivated to test the artifacts thoroughly if they are concerned about possible 2 am calls. Yes, it would be best to aim for near-100 per cent of test automation coverage.
13. Reevaluate your Processes Regularly
Reevaluating your processes is the most crucial part of quality control. Regularly review your procedures and techniques with a mindset that continuous improvement is the goal.
