Monitor steps such as mouse clicks, text input, file downloads, and matching text strings to understand where in the user journey issues may arise.

Partition User Experience Metrics

Break down user experience metrics by device, region, product, or user journey. For example, compare desktop versus mobile usage to identify any discrepancies in performance and optimise accordingly.

Focus on Core Web Vitals

Pay close attention to core web vitals, which are page load user experience metrics defined by Google. These include Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID). Optimising these metrics will improve your users' experience and satisfaction.

Prioritise User Satisfaction

Ultimately, the goal of monitoring user experience is to ensure your users are satisfied with your application's performance. Prioritise their needs and expectations, and be proactive in addressing any issues that may impact their experience.

By implementing these strategies, you can effectively monitor and optimise the user experience of your web application, creating a seamless and enjoyable journey for your users.

Tracking key performance indicators

Some of the key performance indicators that should be monitored include:

• Memory Usage: The amount of RAM the application consumes during operation.
• CPU Usage: The percentage of the CPU's capacity used by the application.
• Latency: The delay between a user's action and the corresponding response from the server.
• Uptime: The amount of time the application is available and operational.
• User Satisfaction: Measured using the Application Performance Index (ApDex), this KPI refers to the overall user satisfaction based on the response times of the application.
• Rate: The RED method, a popular monitoring approach, measures the number of requests handled by the app per second.
• Error: This KPI, also part of the RED method, calculates the percentage of failed requests per second.
• Duration: Another aspect of the RED method, this KPI tracks how long each request takes.

In addition to these, other important metrics to monitor include page load time, error rate, hardware utilisation, software performance, and visual stability.

By tracking these KPIs and metrics, companies can identify patterns, predict problems, and make data-driven decisions to optimise their web application's performance and deliver an exceptional user experience.

Analysing performance data

• Set Clear Objectives: Establish specific, measurable, achievable, relevant, and time-bound goals using the SMART framework. Consider end-user expectations and industry benchmarks to align your objectives with best practices.
• Define Key Performance Indicators (KPIs): Track essential metrics such as server load, error rates, response times, memory usage, CPU usage, latency, uptime, and user satisfaction. These KPIs provide insights into the performance and health of your web application.
• Compare and Benchmark: Utilise performance data to compare your application's performance against competitors and industry standards. This helps identify areas of improvement and ensures your application meets user expectations.
• Analyse User Experience: Monitoring tools can provide insights into user interactions, such as click rates, navigation patterns, and user satisfaction scores (ApDex). Analysing this data helps identify areas where user experience can be optimised.
• Identify Performance Bottlenecks: By monitoring various metrics simultaneously, you can pinpoint potential bottlenecks and anomalies in your application's performance. This proactive approach ensures a seamless user experience.
• Error Tracking and Resolution: Performance data analysis should include tracking errors, crashes, and issues. Identify their root causes and implement fixes promptly to enhance application stability and user experience.
• Security and Compliance: Regularly monitor for security vulnerabilities and compliance issues. Addressing these aspects is crucial to protect sensitive user data and maintain legal and regulatory standards.
• Continuous Improvement: Analyse performance data to identify trends and patterns. Conduct regular performance audits to optimise your application continuously and maintain its health and efficiency.
• Customise Alerts and Notifications: Configure alerts and notifications for critical issues and deviations from expected performance thresholds. This enables your team to take prompt action and minimise downtime.

By effectively analysing performance data, you can ensure that your web application delivers a seamless, secure, and satisfying user experience while meeting your business goals and industry standards.

Setting performance objectives

Define Clear Objectives

Articulate specific and measurable goals that are aligned with your business objectives and end-user expectations. Utilise the SMART framework (Specific, Measurable, Achievable, Relevant, and Time-bound) to set performance objectives. This ensures that your targets are well-defined, realistic, and bound within a particular timeframe. When setting these objectives, refer to industry benchmarks to guide your goal setting and identify areas requiring improvement.

Identify Key Performance Indicators (KPIs)

KPIs are essential metrics that provide insights into your web application's performance. They include metrics such as server load, error rates, response times, memory usage, CPU usage, latency, uptime, and user satisfaction. Monitoring these KPIs allows you to identify patterns, predict potential issues, and make data-driven decisions to optimise your application's performance.

Monitor User Experience

In addition to tracking technical KPIs, it is crucial to consider the end-user's experience. Monitor the Application Performance Index (ApDex) score, which quantifies user satisfaction levels based on the performance and speed of your application. A higher ApDex score indicates higher user satisfaction.

Set Benchmarks and Track Progress

Compare your web application's performance against industry benchmarks to identify areas where you can improve. Regularly track your progress against these benchmarks to ensure that your application remains competitive and meets user expectations.
