Quality assurance sem7 (unit3) hand written notes pdf

Quality control is the process of ensuring that a product or service meets established quality standards. It involves systematic measures that are applied throughout the production process to identify and eliminate defects or inconsistencies that could affect the overall quality of the final product. Quality control is an essential part of any business to ensure customer satisfaction, meet regulatory standards, and maintain the reputation of the company.

The main purpose of quality control is to prevent problems from occurring and to detect them early when they do occur. Quality control measures include monitoring the product or service at various stages in the production process, testing the product for defects, and correcting any issues that are identified. Quality control also involves implementing procedures and policies that ensure consistency and accuracy in delivering a quality product or service.

Quality control systems typically involve the following stages:

1. Quality planning – setting quality goals and developing a plan to achieve them. This includes identifying the product requirements and customer needs, defining quality standards and specifications, and establishing inspection and testing procedures.

2. Quality control during production – monitoring and controlling the production process to ensure that quality standards are being met. This includes inspection and testing of raw materials, work in progress, and finished products.

3. Quality control after production – conducting final inspections and testing to verify that the product meets the quality standards and requirements.

4. Continuous improvement – identifying areas for improvement in the quality control process and implementing changes to improve the quality of the product or service.

Some specific techniques or tools used in quality control include statistical process control, benchmarking, Six Sigma, and Total Quality Management. By implementing a comprehensive quality control system, companies can ensure that their products or services consistently meet or exceed customer expectations and regulatory requirements.
