While theories provide valuable insights, genuine learning often stems from practical, real-world use cases. Let's explore the tangible impact and outcomes of measuring user experience, drawing from my participation in the 2023 UXInsight conference. In this event, I shared insights on how the measurement of user experience directly influences service quality, thereby shaping positively the trajectory of business performance.

Among the array of UX metrics available for evaluating service quality, such as SUS, there exists an untapped opportunity for IT professionals to quantitatively analyze experiences, identify areas for improvement, and shed light on growth prospects. Effectively communicating these insights can resonate powerfully with stakeholders, product managers, executives, and especially the leadership.

In the next video, I share a comprehensive framework for selecting the most suitable measurement tools according to your business context and goal.
