Worst Experience Indicator
Customer experience measurement platform developed by Erik Ingvoldstad and built by Acoustic (Acoustic Pte. Ltd.), grounded in expectancy-disconfirmation theory (Oliver, 1980). Captures pre-experience expectation and post-experience reality on a 1 to 10 scale at specific Points of Experience (PoE), plus one open question ("What was the single worst part?") grouped into stable, trended themes.
WXI is a customer experience measurement platform that evaluates user experiences by comparing pre-experience expectations with post-experience realities on a 1 to 10 scale. It captures feedback at specific Points of Experience (PoE) and includes an open-ended question to identify the worst aspect of the experience, organized into stable themes.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
