Multi-Platform UI/UX System for Property Rental Management
Heuristic Evaluation and Multi-Device Workflow Design

Project Overview

This project involved designing a complete, implementation-ready user interface for UMGC Property Rentals, a fictional property management company that supports both internal office staff and external rental customers. The goal was to create a cohesive, multi-platform user experience spanning desktop, web, and mobile applications, while accounting for the distinct needs, workflows, and constraints of each user group.

​

The final deliverable is a comprehensive User Interface Design Document supported by detailed, high-fidelity prototypes suitable for direct handoff to engineering teams.

Problem Statement

UMGC Property Rentals requires a system that allows:​

  • Office staff to enter, manage, and maintain detailed property listings using a desktop application.

  • Prospective renters to search, view, and inquire about properties using web and mobile platforms.

The challenge was to design a unified interface ecosystem that supports different interaction models while maintaining consistency, usability, and clarity across all platforms.

Scope & Assumptions

  • Property owners do not directly interact with the system.

  • Only core workflows for staff and renters were designed.

  • Authentication is used selectively, only where necessary.

  • The design emphasizes realistic, production-level detail rather than conceptual wireframes.

Design Approach

The project followed a user-centered, task-driven design process:

  • Identified distinct user roles and responsibilities.

  • Designed complete screen flows for each platform.

  • Ensured layouts reflected platform-specific interaction patterns.

  • Applied usability heuristics studied in coursework.

  • Prioritized clarity, error prevention, and task efficiency.

​All interfaces were designed as full screens rather than isolated components to ensure realistic navigation and interaction flow.

Platform Breakdown

Desktop Application (Office Staff)

  • Property creation and management workflows

  • Add, update, and delete property features

  • Structured data entry forms optimized for accuracy

  • Clear navigation and feedback for administrative tasks​​

Web Application (Prospective Renters)

  • Property search with relevant filtering criteria

  • Property detail pages with images and feature lists

  • Simple inquiry and contact flows

  • Web-specific navigation and scrolling considerations​​

Mobile Application (Prospective Renters)

  • Mobile-optimized search and browsing

  • Touch-friendly layout and controls

  • Simplified navigation via menu icons

  • Responsive layouts tailored to small screens

Tools & Technologies

  • Pencil – Rapid UI prototyping and mockup creation

  • Microsoft Word – Formal UI Design Document authoring

The resulting prototypes contain sufficient detail for a development team to implement without additional clarification.

Usability & Design Principles

  • Applied established usability heuristics (e.g., consistency, visibility of system status, error prevention).

  • Ensured logical screen flow and task completion paths.

  • Maintained consistency across platforms without forcing uniform layouts.

  • Designed with accessibility and clarity in mind.

Key Takeaways

  • Designing for multiple platforms requires balancing consistency with platform-specific expectations.

  • Clear separation of user roles simplifies system design and reduces cognitive load.

  • Detailed interface documentation greatly improves implementation readiness.

  • Strong UI design benefits from thinking in terms of systems, workflows, and failure prevention—not just visual layout.

Outcome

This project demonstrates my ability to design complex, multi-platform systems, think through user workflows, and produce professional-grade documentation that bridges design and implementation.
