Due to the constant pressure to release a feature as soon as possible, many tests are deprioritized because the feature are considered simple. However, these features can have non-functional requirements that can affect the user impression of the system. This paper proposes an approach to performance test that uses user experience (UX) as an indicator of what should be prioritized. Through this approach we can identify performance risks and underestimated tests to take actions to improve user flows and mitigate failures in order to achieve the project’s success criteria.

contributes to the ability to make progress on the goal
and track that progress.

Tuning consists of finding and eliminating bottlenecks
— a condition that occurs, and is revealed, when a
piece of hardware or software in a server approaches
the limits of its capacity.
