How do quality assurance and quality control differ?

Quality assurance prevents defects through process improvements, while quality control identifies and fixes defects in the final product. QA is proactive, whereas QC is reactive.

What is the difference between Quality Assurance (QA) and Quality Control (QC)?

Quality Assurance (QA) focuses on improving processes to prevent defects, while Quality Control (QC) involves identifying defects in the final product. QA is process-oriented, while QC is product-oriented. Both are crucial for software quality management. Together, they help ensure that software meets customer expectations and regulatory requirements.

Why is QA essential in software development?

QA ensures software meets business requirements, enhances user satisfaction, and reduces costly defects. It enables early issue detection, improving overall development efficiency and product reliability.

What are the key principles of software quality assurance?

Software quality assurance follows principles like continuous improvement, defect prevention, process standardization, risk management, and compliance with industry best practices.

How does quality control improve software reliability?

QC detects and resolves defects before release, ensuring the software performs as expected. By conducting rigorous testing and validation, QC enhances stability and user confidence.
