The performance of a client-facing application is the measure of how well the application meets the expectations and requirements of the clients who use it. The performance of a client-facing application can be affected by various factors, such as functionality, usability, reliability, availability, security, and scalability. Continuously monitoring the performance of a client-facing application is the process of collecting, analyzing, and reporting on the performance data and metrics of the application over time. Continuously monitoring the performance of a client-facing application can help identify and resolve issues, improve quality, optimize resources, and enhance client satisfaction. The most important thing to ensure when continuously monitoring the performance of a client-facing application is that the objectives are confirmed with the business owner. The business owner is the person or entity who has the authority and responsibility for the business value and outcomes of the application. The business owner defines the objectives, goals, and requirements of the application, and sets the performance criteria and targets. Confirming the objectives with the business owner can help ensure that the performance monitoring is aligned with the business needs and expectations, and that the performance data and metrics are relevant, accurate, and meaningful. References = Risk and Information SystemsControl Study Manual, Chapter 4: Risk and Control Monitoring and Reporting, Section 4.3: Continuous Monitoring, p. 203-205.
