Abstract

This case study explores a User Interface and User Experience (UIUX) redesign project for Grab, Southeast Asia’s leading super-app, focusing on its food delivery functionality. The goal was to enhance usability, streamline interactions, and address pain points faced by users, particularly in the order placement and delivery instruction process.

User Research

To guide the redesign, I analyzed Grab’s core users; tech-savvy millennials in Southeast Asia who frequently order food. Creating a detailed user persona helped identify key pain points such as unclear delivery instructions and cluttered checkout flows. This research directly informed solutions like visual drop-off guides and streamlined payment, ensuring the design addressed real user needs while maintaining Grab’s intuitive experience.

Hierarchical Task Analysis

I conducted a Hierarchical Task Analysis to map critical user flows like ordering and delivery setup. This revealed friction points, such as inefficient navigation, which informed streamlined interactions in the final design.

Gestalt Principles Analysis

For this redesign, I selected key screens that represented core user journeys; homepage, ordering, item/restaurant selection, and delivery setup. The selected screenshots showcase key interfaces from Grab's food delivery app, where I analyzed how Gestalt principles were already implemented to enhance usability.

Wireframing

I developed iterative wireframes to enhance the user experience, focusing on key screens including the homepage, ordering, item/restaurant selection, and delivery setup.
