Qualitative risk analysis: A method of risk assessment that uses subjective judgment and expert opinions to evaluate the likelihood and impact of risks. It is used in risk management to prioritize risks and develop mitigation strategies. Examples include interviews, workshops, and scenario analysis.

Quality Assurance (QA): A systematic process of ensuring that products and services meet specified requirements and are reliable, defect-free, and fit for purpose. QA practices involve the implementation of standards, testing, and review to uphold product quality and customer satisfaction.

Quality (in IT): Refers to the degree to which an IT system, application, or process meets specified criteria, user requirements, and performs reliably and efficiently. Quality in IT is maintained through best practices, testing, and continuous improvement.

Quality management system (QMS): A framework of policies, procedures, and processes that are used to plan, implement, and monitor the quality of a product or service. It is used in organizations to ensure customer satisfaction and compliance with standards. Examples include ISO 9001, CMMI, and Six Sigma.

Quality of Service (QoS): The performance level of a network or internet connection that determines the speed and reliability of data transmission. It is used in networking and telecommunications to ensure that data is transmitted smoothly and efficiently. Examples include prioritizing certain types of data traffic, such as video streaming or voice calls, and implementing bandwidth allocation mechanisms to prevent network congestion.

Quantitative Risk Analysis: A systematic process used in risk management that quantifies the probabilities and potential consequences of risks. It typically involves the calculation of risk through the formula - Risk = Probability of Occurrence × Impact of Event. This technique allows organizations to assign monetary values to risks and to prioritize them based on their potential to affect business outcomes.
