We used severity rating as it helps to identify and prioritize usability issues that affects the user experience of our application. It helped us in quantifying how serious or critical a usability issue is, based on its impact on the user and the frequency of occurrence.

By assigning a severity rating to each usability issue, the team prioritized which issues to address first. Critical and major issues were addressed immediately, while cosmetic and minor issues were address later on.

We used Jakob Nielsen’s severity ratings for this milestone.

The Jakob’s severity of a usability problem is a combination of three factors:

The frequency with which the problem occurs
The impact of the problem if it occurs
The persistence of the problem
