The goal behind setting up a UX measure is to able to evaluate a feature, product, or service against a repeatable protocol that aligns with key performance indicators. The measure is something that should be repeated at a regular time interval. The measure won’t necessarily tell us why something is or is not performing well, but it will tell us if it is.

One measure we recommend is a repeatable survey, like SUS or NPS. It’s also possible to make a unique survey as required. SUS will give you a usability score; NPS will give you a product satisfaction score. These two surveys are well established and validated, and the protocol is free to use. These surveys do require a fairly large sample size, usually well over 100 users.

Another good measure is a summative user test or baseline test. This type of test is very similar to an evaluative test, however there is a rigid pass-fail criterion for each task, and there are less qualitative or exploratory conversations between the moderator and the user.

Scope

Surveys take about a month to design, program, deploy, analyze, and report.

A typical user test takes 3 weeks to a month.

Deliverables

Surveys provide survey design, raw data, survey analysis, and final report.

User test provide recruitment screener, session guide, participant profiles, topline report, and final report.
