Intro

In the era of mobile internet, being able to handle warehouse materials quickly and flexibly based on business needs is more important than ever. JianLiantong, an internal warehouse management system used by employees of a leading construction group in China, has a fairly complete desktop version — but its mobile app has long been frustrating and hard to use.

To address this, a technology subsidiary of the group commissioned a full redesign of the app. The goal was to bring the most commonly used features from the desktop version onto mobile, while also simplifying the business logic. This way, warehouse staff can manage and process orders anytime, anywhere, right from their phones.

Challenges & Problems

One of the biggest challenges in this upgrade project was the limitation of the existing tech framework — the app needed to be optimized for mobile without introducing any new technical infrastructure. On top of that, as an external designer, I didn’t have direct access to frontline users. Most of the user insights and research had to come indirectly through product managers, the design team, or operations acting on behalf of users.

Process Mapping

By analyzing the user journey and real workflows, I discovered that the core issue with the current app was surface-level digitization. It simply moved paper processes online without really leveraging digital tools to rethink or improve the logic behind those tasks. This led to lots of redundant steps and overlapping functions that made the user experience inefficient. I mapped out all standard workflows and identified four key inventory processes — transfer, purchasing, issuing, and returning — and found shared patterns among them. This allowed me to streamline and simplify those flows by merging common steps.

Design Approach

With those insights in mind, and working within the existing constraints, I focused on reducing repetitive work in the process flow. By breaking down and modularizing each step, I made it easier to reuse parts of the process across different tasks — which helped boost efficiency and made it quicker for users to complete their work orders.
