What is quality control?
Quality control refers to the processing that ensures the product quality is maintained and upgraded. To do so, the company designed a chain of command that includes the chief operating officer to the end level of employees who ensure the product quality is up to the mark and will satisfy the customer needs; this processing is known as quality control. Since the quality of the product depends on quality control, the organization ensures that quality control processing is error-free by training its employee, which involves several steps to check the product value. For instance, before selling off the furniture, the furniture manufacturing company examines multiple times whether the product is all good to run for decades. It means that the goal of quality control is to testify and correct all the issues with the product before it reaches the end customer.
Quality metrics refer to the ways that measure and evaluate the quality of a product, service, or process. It assists the company in knowing if the customer is satisfied or dissatisfied with the product. Quality metrics include:
- Defect density: it counts the number of defects per unit of measurement (e.g. per software module or manufactured item).
- Cycle time: how much time it has taken to complete a process or produce a product.
- Customer satisfaction measures how well the product or service meets customer expectations.
- Compliance: the extent to which a product or service complies with relevant regulations and standards.
- Error rate: the number of errors made during the manufacturing process.
- Reliability: the likelihood of a product or system performing its intended function for a specified period.
- Usability: the simplicity of usage of a product.
These metrics can be used to judge and improve quality, identify areas for improvement, and assess the effectiveness of quality control processes.
