Dex app redesign

Problem statement

Dex’s existing app was difficult to navigate, causing friction in shift scheduling, task management, and fault reporting. Employees, managers, and HQ managers had different but overlapping needs, requiring a more intuitive and adaptable solution.

Goal

Redesign Dex to streamline shift scheduling, task assignments, and fault reporting, ensuring a seamless experience for all user roles while improving oversight and efficiency.

Design challenge

Balance the varying needs of employees, managers, and HQ managers by creating an adaptable interface that allows clear task management, scheduling, and reporting without complexity.

KPIs

Success will be measured by:

  • Task Completion Rate: How easily employees accept shifts, report faults, and complete tasks.

  • Manager Efficiency: Time taken to schedule shifts, assign tasks, and oversee operations.

  • User Adoption: Active users and engagement with key features.

Research

User research

For user research, we conducted a field study at a restaurant, observing how waiters and managers managed tasks before their shifts. The process was inefficient, relying on fragile paper schedules that could easily be lost. We also held a workshop with the app owners to define user needs and challenges.

Market research

I analyzed task management, logistics, and fault reporting apps, focusing on navigation, scheduling, and fault management for different user types.

Research insights

Our field study and market research revealed the following insights:

  • Task setup must be quick and seamless.

  • Users need motivation to complete tasks.

  • Most task management apps lack fault reporting—an opportunity for Dex.

  • Different user roles require tailored features (e.g., admin controls).
