How do we craft case studies that clearly show UX metrics in action?

Understanding users

Case studies is our next section to tackle on the Glare UX metric pages. We want the case studies to clearly show our UX metrics in action, providing an example that your team can follow to test your own user experiences like landing pages or product dashboards.

It’s easy enough to show the work and result of the case study, but we want to format these stories in a way that easiest for product teams to digest and replicate in your own work.

Below is what we have so far: our first stab at the copy for the case study section on our Usefulness UX metric page.

:speech_balloon: Does is clearly convey how the UX metric was used? Is this something you think your team can use to start testing your own designs with UX metrics? We’d love to hear your thoughts!

How Getup Measured Usefulness of Their “Try On in Store” Feature
An e-commerce clothing brand called Getup introduced a new “Try On in Store” feature that lets users send clothing items they find online to a nearby retail location for in-person try-ons. To ensure this cross-channel experience felt intuitive and valuable, the team turned to the Usefulness metric.

The Setup
Usefulness is calculated using the UX-Lite method, which pairs two core questions:

  1. Ease of use
    How much do you agree with the following statement? “This website is easy to use.”
  2. Effectiveness
    How much do you agree with the following statement? ”This website’s features meet my needs.”

These responses generate an Ease Score and an Effectiveness Score, which are then averaged to produce a single Usefulness score.

The Results

  • The Try On in Store feature received a Usefulness score of 79%, rated Good on the Glare scale from Very Poor to Very Good
  • Participants reported an Ease Score of 81.5%, indicating they had little trouble navigating the interface and selecting a nearby store and time
  • The Effectiveness Score, slightly lower at 76.5%, suggested minor friction—most often related to questions about how item availability would be confirmed at the store
  • Users responded positively to the concept, with many saying it “bridged the gap” between online browsing and in-store shopping

The Impact

These findings helped the Getup team prioritize adding more real-time inventory messaging and clearer confirmation steps. The solid Ease and Effectiveness ratings showed that the design was working well, but that addressing uncertainty around follow-through could make the feature even more valuable.
