How might we preserve familiar workflows in Horizon while introducing new features that enhance efficiency and flexibility, ensuring a seamless transition for experienced users

Design Process

Information Architecture

I audited the existing app’s information architecture and user flows through task analysis, uncovering issues like confusing navigation, unnecessary steps, and workflow gaps. Collaborating with cross-functional teams in design studio workshops, I developed a new, streamlined information architecture that optimized the hierarchy based on user priorities.

I preserved familiar user flows while adding advanced features to improve functionality, ensuring navigation remained intuitive. Critical tasks, such as starting inspections, checking schedules, and reviewing reports, were mapped to guide users through time-based and action-based workflows effectively.

Iterating and Testing

I began by sketching low-fidelity concepts for the new navigation, home screen, and primary workflows, then advanced to mid-fidelity wireframes in Figma to structure content and layouts. Using these, I developed interactive prototypes to test critical user paths. Prototypes were iteratively refined based on usability testing with inspectors, as well as internal design critiques.

Landing on the Final Solution

The final design included:

Design solution for navigation complexity

Simplified Navigation

One key insight from my research was the complexity of navigation and content organization, particularly on the current home page. To address this, I introduced a streamlined navigation system, quick actions, and clear status indicators, reducing interaction steps by 50%. The new card-based layout with a timeline structure highlights critical information, while quick message templates and organized contacts improve communication workflows.

Before
Information Architecture

  • No clear indication of what actions are available

  • No way to quickly sort or filter appointments

  • No visual distinction between past/future appointments

    Missing Features
    Basic list-only view
    No status indicators

Design solution for photo management problems

Streamlined photo management workflow

The legacy app lacks a dedicated photo gallery for users to view and organize captured images a major pain point for the majority of the users. The "SpareTab" feature allows users to take pictures but can only be viewed on the web, not in the mobile app. To address this, I introduced a photo gallery section for automatic photo categorization, enabling better organization and viewing of photos within the app.

Deep nested navigation

Due to the deep nesting nature of inspections, users sometimes get confused about which part of the property they are documenting. The legacy app used breadcrumb navigation for clarity, which I initially removed, assuming the back button would suffice. However, after user testing, it became clear that this change was not well-received. As a result, I reintroduced simplified header navigation with a contextual dropdown, which only appears when users reach the third layer or deeper, ensuring the interface stays clear while guiding users through more complex levels of the inspection.

Breadcrumbs navigation on legacy app

Before

  • Uses backslashes (\) instead of standard forward slashes (/) or (>)

  • No spacing around separators making it hard to read

  • Abbreviated terms ("Ro" instead of "Roofing")

  • No visual distinction between levels

  • No visual feedback for current location

  • Low contrast gray text on dark blue is hard to read

After
Information Hierarchy:

  • Clear back navigation

  • Current context "Roofing material" as large title

  • Dropdown shows full path and marks "Current" location

  • Maintains context without cluttering the interface

After
Field Inspector Benefits:

  • No learning curve - uses patterns they know

  • Large touch targets for gloved hands

  • Clear visibility of current location

  • Quick navigation between sections

  • Minimal cognitive load during inspections

Job details

Based on field inspector feedback highlighting limited mobile capabilities, I optimized the experience by consolidating critical inspection tools—maps, weather data, property details, and document management—into a single, accessible interface. This research-driven solution enables inspectors to conduct thorough assessments entirely from their mobile device, eliminating the previously reported friction of switching between desktop and mobile platforms.
