Product Management can be a challenging role, with demands pulling you in many different ways. So anything we can do to minimise time spent on repetitive tasks or to maximise the value that we get from data should be capitalised to the full.
Usability and user experience are difficult to measure quantitatively. Often, measuring improvements (or regressions) in usability is primarily achieved through monitoring a range of interrelated metrics such as average session length, goal completion rates, defects raised or churn. These metrics, however, can all be influenced both positively and negatively by many factors - not just usability. One way of achieving direct feedback on the usability of a product, and thus being able to more directly measure it, is to use a questionnaire.
As a new feature for the site, I’ve started building a list of common product KPI’s and metrics with simple definitions. It’s certainly a work in progress, and already feels like one of those tasks that’ll never quite be complete, but hey - I thought it might be helpful. If there are obvious KPIs missing (I’m sure there are!) then let me know in the comments.
