Document summary
This document outlines a comprehensive plan/guide towards testing and conducting a System Usability Scale (SUS) for the current savings product which is essential to quantitatively assess its overall ease of use, identify specific usability issues, and gather user feedback to inform targeted improvements for a more intuitive user experience.
Objectives
As part of our ongoing efforts to improve the user experience and align our products with strategic goals, we have identified the System Usability Scale (SUS) score as a key performance indicator (KPI) for user satisfaction. Additionally, we will be tracking two other critical usability metrics: time on task and success rate. These metrics will provide a comprehensive view of how well our product supports primary user goals across web and mobile platforms.
The purpose of this usability test is to establish a usability benchmark for the product, which will serve as a foundation for future improvements.
