EVOS Dashboard

Saas - Web UI Design

2025

This project focuses on optimizing the legacy version of the dashboard. Our goal is to meet the evolving needs of Admin users across different markets through a redesigned, updated dashboard experience. The optimization adopts a full reload approach, involving a complete overhaul of the interface and underlying structure.

Customer Overview

The Noodoe EVOS Dashboard serves users across five continents and over 75 countries. For this redesign project, we focused on the North American market, conducting in-depth interviews with several established EV charging service providers who maintain close partnerships with us. Through these discussions, we discovered that users rarely spend extended time on the dashboard. Instead, their primary usage occurs during end-of-month financial reporting. As a result, month-over-month financial metrics are particularly critical. In addition, users expressed the need for a quick understanding of current station utilization trends and timely alerts for error detection and resolution.

UX Methodologies & Insights

  • Stakeholder Interview – Project Initiation Phase

    We interviewed external partners and real users to clarify actual market usage scenarios, strategic priorities, and underlying data structures. These insights helped us align the design focus with actionable financial and operational indicators, ensuring our solutions supported broader business goals.

  • Affinity Mapping – Early Project Phase

    We synthesized insights from cross-functional interviews and user research through affinity mapping, identifying three key user needs: quick access to financial summaries, real-time error alerts, and visualized usage trends. These became the foundation for our design strategy.

  • Heuristic Evaluation – Mid-Project Phase

    We conducted a heuristic evaluation of the existing dashboard, revealing issues such as disorganized information hierarchy, lack of real-time feedback, and cognitively demanding data presentation. These systemic pain points provided a clear direction for redesign improvements.

Evaluation Criteria

Role-Based Data View and Control

Admins can define which data sets are visible to different user roles. The dashboard dynamically adjusts its content based on login credentials. Users can also switch perspectives to view data relevant to other roles, enabling clearer cross-functional understanding and more efficient collaboration within a multi-role environment.

Flexible Widget Management

The EVOS Dashboard features a modular widget system that allows users to add, remove, or reorder data components based on operational needs. With a real-time "what-you-see-is-what-you-get" editing interface, the dashboard can adapt seamlessly to evolving business requirements, ensuring long-term scalability and usability.

Instant Error Detection, Three-Step Fix

The dashboard’s entry page integrates real-time error detection, instantly highlighting anomalies and guiding users to resolution. Every task is designed to be completed within three steps, ensuring users can quickly identify issues, access essential data, and resolve problems—streamlining the energy system’s daily operations.

Design Highlights

In this project, we reimagined the traditional dashboard layout by implementing a Z-pattern visual structure. This approach mirrors the natural way humans scan content, especially under data-heavy or locked-state conditions. Adopting this layout was a key design principle established early in the project.

The dashboard is horizontally divided into three core functional zones:

  • Quick Access Zone – Optimized for high-frequency actions and shortcuts

  • Widget Data Zone – A flexible area for key modular insights

  • Error List Zone – Displays real-time system alerts and resolution guidance
