<p class="para">Once the work of building the application is finished, the technical architect is often asked to lead performance-testing activities and ensure that the application is production ready. At this stage, the architect's primary objective is improving application performance, stability, and operational readiness. To achieve this goal, the architect needs to conduct performance tests and make performance improvements, recommend changes to make applications easier to monitor and support, and identify candidates for code refactoring.</p>
<p class="para">This section guides you through these activities. In it, you will learn how to:</p>
