Quality Assurance and Quality Control
Quality Assurance and Quality Control are two important concepts in ensuring that products and services are of the highest quality. While they are related, they are not the same thing.
Quality Assurance
QA is the process of implementing a system of policies, procedures, and standards to ensure that the product or service being produced is of the highest quality. It involves a proactive approach to quality, where the focus is on preventing defects and ensuring that the product meets the necessary standards.
Quality Control
On the other hand, is the process of inspecting, testing, and verifying that the product or service meets the necessary quality standards. It’s a reactive approach to quality, where the focus is on finding and correcting defects after they have occurred.
Relationship to Quality Assurance
Simply put, Quality Assurance provides the framework for Quality Control to take place. Quality Assurance lays the foundation for Quality Control to ensure that the right processes and standards are in place and that the product or service is being produced to the right level of quality.
Quality Control then takes over to verify that the product meets the necessary standards and to identify and correct any defects that may have occurred.
| Feature | Quality Assurance (QA) | Quality Control (QC) |
| Main Goal | Making sure how you build is good. | Making sure the finished car is good. |
| How it Works | Tries to prevent mistakes from happening. | Tries to find mistakes after they happen. |
| When it Happens | Mostly before & during the building. | Mostly during & after the building. |
| Who Does It | It’s everyone’s job on the team. | Usually, specific inspectors or testers. |
Types of Quality Control
There are several different types of Quality Control methods, each with its specific focus and methods. Here’s a brief overview of the most common types of Quality Control:
1. Process Control:
This type of Quality Control focuses on monitoring and controlling the processes used to produce a product. Think of it like a traffic cop directing the flow of cars, but for a production line! By keeping an eye on the process, you can identify any bottlenecks or issues and make improvements to increase efficiency and quality.
2. Control Charts:
Control charts are like a dashboard for Quality Control. They show how a process is performing over time, and allow you to quickly identify any trends or patterns that may indicate a problem. By monitoring control charts regularly, you can detect issues before they become major problems and make changes to keep your process running smoothly.
3. Acceptance Sampling:
Acceptance sampling is like checking a random sample of items from a batch of production. This type of Quality Control is used to determine if the batch meets the required standards. If the sample meets the standards, the entire batch is accepted, but if the sample fails, the entire batch is rejected.
4. Product Quality Control:
This type of Quality Control focuses on the end product itself. It involves testing and examining the product to ensure it meets the required specifications and standards. Product Quality Control helps catch defects or issues before the product is released to customers, ensuring they receive a high-quality product.re it meets the required specifications and standards. Product Quality Control helps catch defects or issues before the product is released to customers, ensuring they receive a high-quality product.
- Pareto Charts: These charts basically show the most common issues in a single bar graph. They follow the 80/20 rule, which means fixing 20% of the main problems and solving 80% of the challenges that we faced during the process.
- Control Charts: They are used to measure how well something is going. They look like a line graph and help to see when something is not going as well as expected.
- Fishbone or Ishikawa Diagrams: They get their name from looking like a fish skeleton. They help identify the cause of a problem by sorting possible solutions into categories such as People, Methods, Machines, and others.
- 5 Whys: By asking “Why?” five or more times, you can understand the reason behind a problem.
- Check Sheets: They provide an easy way to get information. You can use them to keep track of how often certain things happen, like making mistakes.
- Scatter Diagrams: They show the relationship between two different subjects, like temperature and machine errors. They are important for identifying patterns.
- Six Sigma: These tools focus on data and results. They aim to improve the overall quality of a process by removing any variances and defects.
