Quality is everyone’s responsibility.
W. Edwards Deming
In today’s fast-paced and competitive business world, quality control is an essential element for any organization to succeed. Quality control is the process of ensuring that products or services meet or exceed customer expectations and industry standards. This process involves monitoring and evaluating various aspects of the production process to identify and correct any defects or flaws.

Quality Control
Quality control is the process of ensuring that products or services meet or exceed customer expectations and industry standards. It involves monitoring and evaluating various aspects of the production process to identify and correct any defects or flaws. The goal is to ensure that the end product or service meets the desired level of quality and consistency, and is delivered to the customer with minimal defects or issues.
It can involve a range of activities, including inspections, testing, and auditing. Inspections involve visually inspecting a product or service to identify any defects or issues, while testing involves subjecting a product or service to various tests to evaluate its quality and performance. Auditing involves reviewing processes and procedures to ensure they meet industry standards and regulations.
Quality control is important in ensuring customer satisfaction, building a reputation for quality products or services, reducing costs associated with defects and recalls, and complying with industry regulations and standards. It is an ongoing process that requires continuous monitoring, evaluation, and improvement to ensure the highest level of quality is maintained.

What are the 4 types of quality control?
There are four main types of quality control:
1. Plan: The first step in quality control is to plan for the process. This involves establishing the quality standards and specifications, setting goals and objectives, identifying the resources needed to achieve those goals, and creating a plan for monitoring and measuring the results.
2. Do: The second step is to implement the plan. This involves putting the plan into action, executing the procedures and processes as specified, and collecting data to monitor the results. During this step, it is important to ensure that the plan is being followed correctly, and that any issues or problems that arise are addressed in a timely manner.
Leader’s Tip:
Establish clear quality control objectives, criteria and indicators to guide and measure the effectiveness of quality control activities.
3. Check: The third step is to check the results of the implementation. This involves comparing the results to the established standards and specifications, analyzing the data collected, and identifying any deviations or issues that need to be addressed. This step is critical to ensuring that the plan is effective and that the desired results are being achieved.
4. Act: The fourth and final step is to take action based on the results of the check step. This involves making adjustments and improvements to the plan and processes based on the data collected, implementing corrective actions to address any deviations or issues, and continuously monitoring and measuring the results to ensure ongoing improvement.
This step is critical to ensuring that the quality control process is effective and that the desired level of quality is being achieved.
Leader’s Tip:
Emphasize the importance of training, empowering and involving employees in quality control processes for optimal results.
What are the three C’s of quality control?
The three C’s of quality control are:
- Compliance: Compliance refers to the adherence to established regulations, standards, and procedures. In quality control, compliance is important to ensure that products or services meet the required legal and industry standards.
- Consistency: Consistency refers to the ability to produce products or services that meet the same quality standards and specifications consistently over time. Consistency is important to ensure that customers receive products or services that meet their expectations every time.
- Continuous Improvement: Continuous improvement refers to the ongoing process of improving the quality of products or services by identifying and correcting any issues or defects in the production process. Continuous improvement is important to ensure that the quality of products or services is always improving, and that the organization is keeping up with changing customer expectations and industry standards.
What is 7 QC tools?
The 7 QC tools are a set of basic quality control tools used for process improvement. They were developed by Kaoru Ishikawa, a Japanese quality control expert, and are also known as the 7 Basic Tools of Quality Control. The 7 QC tools are:
- Cause and Effect Diagram (also known as Fishbone or Ishikawa diagram): This tool is used to identify the root cause of a problem by breaking down the factors that contribute to the problem into smaller categories.
- Check Sheet: This tool is used to collect and analyze data by creating a standardized form to record the frequency of an event or defect.
- Control Chart: This tool is used to monitor the performance of a process over time by plotting data points on a chart to identify patterns or trends.
- Histogram: This tool is used to visually display the distribution of data by grouping data into categories and creating a bar chart to show the frequency of each category.
- Pareto Chart: This tool is used to identify the most significant causes of a problem by ranking them in order of frequency or impact.
- Scatter Diagram: This tool is used to identify a correlation or relationship between two variables by plotting them on a graph.
- Stratification: This tool is used to separate data into different categories to identify patterns or trends that may not be visible when the data is analyzed as a whole.
The 7 QC tools are widely used in quality control and process improvement, and can help organizations identify and correct problems, reduce defects and waste, and improve overall efficiency and productivity.
FAQs
What is the purpose of quality control?
The purpose of quality control is to ensure that products or services meet the desired level of quality and conform to established standards, specifications, and customer expectations. Quality control helps to identify and correct any issues or defects in the production process, improve efficiency and productivity, reduce waste and costs, and ultimately, increase customer satisfaction.
What is the difference between quality control and quality assurance?
Quality control focuses on monitoring and controlling the production process to ensure that products or services meet the desired level of quality. Quality assurance, on the other hand, focuses on preventing defects or issues from occurring in the first place by establishing quality standards and procedures, and ensuring that they are followed consistently.
What are the 4 types of quality control?
There are four main types of quality control: Statistical Quality Control, Inspection , Testing, Process Control.
What is quality control and example?
Quality control is the process of ensuring that products or services meet or exceed customer expectations and industry standards. It involves monitoring and evaluating various aspects of the production process to identify and correct any defects or flaws. The goal of quality control is to ensure that the end product or service meets the desired level of quality and consistency, and is delivered to the customer with minimal defects or issues.
