What is Quality Assurance. Difference between Quality assurance and Quality control

Question

Accepted Answer

Quality assurance is the process of ensuring that a product or service meets the desired level of quality.

Quality assurance involves the creation and implementation of processes and procedures to ensure that a product or service meets the desired level of quality.
Quality control involves the inspection and testing of a product or service to ensure that it meets the desired level of quality.
Quality assurance is a proactive process that focuses on preventing defects from occurring, while quality control is a reactive process that focuses on identifying and correcting defects after they occur.
Examples of quality assurance activities include developing quality standards, conducting audits, and implementing continuous improvement processes.
Examples of quality control activities include product testing, inspection, and defect analysis.

Accepted Answer

Quality Assurance (QA) is a set of activities and processes designed to ensure that the products or services being developed or delivered meet specified requirements and standards. It is a systematic approach that focuses on preventing defects and errors rather than detecting and fixing them after they occur.

The main objective of QA is to establish and maintain processes that can consistently deliver high-quality products or services. It involves planning, designing, implementing, and monitoring various activities to ensure that the desired level of quality is achieved. QA is typically performed throughout the entire development or production lifecycle.

On the other hand, Quality Control (QC) is a subset of QA and refers to the actual inspection and testing of products or services to identify defects or deviations from the desired quality. It involves activities like product inspections, sample testing, and measurements to ensure that the final output meets the specified quality standards.

The main difference between QA and QC can be summarized as follows:

1. Focus: QA focuses on preventing defects by establishing processes and standards, while QC focuses on identifying defects through inspections and testing.

2. Timing: QA is performed throughout the entire development or production process, starting from the planning phase. QC is typically performed at the end of the process when the products or services are being evaluated before delivery.

3. Scope: QA is broader in scope and involves activities like process design, documentation, training, and continuous improvement. QC is narrower in scope and concentrates on the inspection and testing activities.

4. Responsibility: QA is the responsibility of the entire team or organization involved in the development or production process. QC is usually the responsibility of a dedicated quality control team or department.

In summary, QA is a proactive approach that focuses on preventing defects, while QC is a reactive approach that focuses on identifying and fixing defects. Both QA and QC are essential components of a comprehensive quality management system to ensure that products or services meet the desired quality standards.
