A global bank is piloting a revamped mobile app. Executives request an objective, industry-benchmarked metric that captures users' perceived usability so progress can be tracked across monthly releases and compared against competitor products. Which measurement approach should the program manager implement first?
Run a post-release System Usability Scale survey and compare results to the 68-point industry benchmark.
Conduct quarterly Net Promoter Score phone surveys.
Analyze revenue per active user from the app store.
Monitor service-desk defect density as a usability proxy.
Administering the System Usability Scale (SUS) after each release yields a standardized score derived from a validated ten-item questionnaire. Because extensive normative data place the global average around 68, the program manager can trend scores over time and gauge how the app compares with other software. Net Promoter Score focuses on loyalty rather than usability, defect density reflects quality but not end-user perception, and revenue per user is influenced by factors outside user experience, making these metrics less suitable for the stated need.
