Usability Case Study

THE PROBLEM

THE PROBLEM

A management database system with a mix of bad and good design.

THE DESIGN

THE DESIGN

  • Systems Usability Scale Survey

  • Heuristic evaluation

  • Usability testing 

  • Contextual Inquiry

THE FINDINGS

THE FINDINGS

Both Usability Scale and heuristic evaluation contradict staff members who generally have a positive attitude toward the product. Users are unaware that there are various ways to perform an individual task. The average users takes 15 clicks to complete a task.

THE EVALUATION

There were many factors that affected the outcome of this study. A small sample size of participants was statistically not enough to yield solid data from the SUS survey. Furthermore, since the usability study was analyzing a mock task, the time to complete the task, and number of clicks it yielded, were inaccuarte. Contextual observation shows users multitasking, often working with one free hand, and bouncing between screens, thereby increasing the number of clicks and time it takes to complete the task.
