What is quality assurance (QA)?

Quality Assurance (QA) is a set of processes and methodologies aimed at preventing defects in a product or service at all stages of the development lifecycle. QA focuses on improving the process itself to avoid errors in the future, unlike Quality Control (QC), which is focused on identifying defects in the finished product.

Key aspects of QA:

• Quality Planning: Defining standards, goals, and quality metrics.
• Process Development: Describing and documenting workflows to ensure repeatability and compliance with standards.
• Training: Enhancing team skills to improve work quality.
• Process Audits: Regular checks for compliance with established standards.
• Metrics Collection and Analysis: Measuring and analyzing quality data to identify problem areas and improve processes.
• Corrective and Preventive Actions: Implementing measures to eliminate root causes of defects and prevent their recurrence.

QA is a proactive approach aimed at creating a quality product from the first attempt, ultimately reducing costs and increasing customer satisfaction.
