Quality control verifies code for vulnerabilities, ensures adherence to security protocols and standards, conducts rigorous testing for potential breaches, implements encryption and access controls as needed, Monitors suspicious activities and threats, and regularly updates security measures for ongoing protection.

93. How does knowledge transfer maintain quality control standards within a team?

Ans:

Sharing expertise across team members enhances collective skills, Ensures consistent understanding and application of quality standards, Facilitates smoother collaboration and communication, Enables efficient problem-solving and decision-making processes, Reduces errors and discrepancies through shared best practices,

94. Why balance manual and automated testing in quality control?

Ans:

• Ensures coverage of edge cases and unexpected scenarios,
• Automated testing speeds up repetitive tasks and regression testing,
• Increases test coverage and accuracy for routine checks,
• Combining both optimizes efficiency and effectiveness,
• It is resulting in robust quality control measures.

95. How does risk assessment affect quality control scope?

Ans:

• Identifies potential weaknesses and vulnerabilities in the project,
• Prioritizes areas of Focus based on potential impact and likelihood,
• Determines the depth and breadth of testing required,
• Guides resource allocation for risk mitigation strategies,
• Ensures comprehensive coverage of high-risk areas,
• It helps in establishing a more targeted quality control approach.

96. Explain defect prevention versus detection in quality control.

Ans:

Defect prevention focuses on eliminating issues at the source, emphasizing process improvements and proactive measures. It aims to reduce the occurrence of defects during development. Defect detection involves identifying and correcting issues post-implementation. It utilizes testing, reviews, and inspections to find and address defects. Both approaches complement each other for comprehensive quality control.
