Reading time 9 min When it comes to managing web performance, it’s vital to be proactive rather than reactive. To accomplish this goal, an organization needs to build internal processes and procedures that can operationalize a performance-first culture. The first step is to establish and implement web performance budgets.

Application performance monitoring (APM) is the practice of tracking key software application performance metrics using monitoring software and telemetry data. Practitioners use APM to ensure system availability, optimize service performance and response times, and improve user experiences. Application performance management.

Site performance is potentially the most important metric. The better the performance, the better chance that users stay on a page, read content, make purchases, or just about whatever they need to do. With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. Lighthouse.

The idea behind these UI decisions is that a badge would let a user know quickly if a site is loading slowly due to a problem on their end (network issue, internet is down, etc) or if the website is known to be built in a way that loads slowly. Most stemmed from Google exercising too much power with this move.

There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. STPA is based on a functional control diagram of the system, and the safety constraints and requirements for each component in the design.
