The Discovery

When I joined Cavisson Systems, I discovered that one of its core enterprise products — the Load Test module — was struggling with major usability and design challenges. Although technically robust, the tool was difficult to use,visually inconsistent, and lacked user-centered design principles.

The Goal

My goal was to make Load Test effortless and intuitive for every user.

Applied Principles:

• Nielsen’s 10 Heuristics: Visibility, Consistency, Feedback, Error Prevention.
• Hick’s Law: Reduced decision points per screen.
• Fitts’s Law: Optimized button placement and target size.
• Gestalt Principles: Improved grouping and visual hierarchy.

Design Focus

• Clear, modular layout with a consistent design system.
• Prioritized important metrics and live test data visually.
• Added contextual help and validation to reduce confusion.
