Designed a functional app for factory workers to track tasks and streamline operations
PROJECT SUMMARY
This project transformed a feature-heavy Operations Management System at Yummi Candles into a simple, functional app for factory workers and supervisors. While core actions existed in Mendix, the interface lacked clarity and structure. We streamlined workflows, automated manual tasks, and gave supervisors a clear view of priorities, using big confirmation dialogs, undo options, locked critical tasks, and simple error explanations to prevent mistakes.
​
I refined and redesigned 50+ Mendix screens, turning existing features into an intuitive, low-friction experience. I focused on reducing cognitive load and creating an interface that felt familiar, reliable, and easy for long-time factory staff to use.

HOW MIGHT WE...
Replace Word-of-mouth Workflows with Reliable, Automated Systems
After shadowing and interviewing workers and supervisors, it became clear that the biggest challenge was the fully manual, word-of-mouth process. Managing and assigning hundreds of orders without any real, consistent system in place was overwhelming and often confusing, slowing productivity across the floor.
I needed to design for users with limited tech comfort, long-established habits, and skepticism toward new tools and technology. The system also had to reduce errors, support safety-critical steps, and work seamlessly across tablets and desktops while remaining simple enough for fast adoption on the factory floor.
OMS PROJECT
Order Overview
This design gives supervisors a clean, scannable view of all orders, with key details and actions surfaced for fast decisions. Clear hierarchy, large buttons, and color-coding support high-volume processing while keeping the workspace simple and intuitive.
OMS PROJECT
Split Order Functionality
Split Order Functionality is one of the factory’s most essential tools, enabling supervisors to break large, time-sensitive orders or partially fulfillable orders into smaller sub-orders so employees can work in parallel. The flow is designed for efficiency and clarity, reducing cognitive load by guiding users through three clean, focused steps.
REVIEW ITEMS
The page provides a clear breakdown of order items, quantities, categories, and priority levels. Supervisors are prompted to choose the number of sub-orders and the reason for splitting, which establishes the context needed for accurate, efficient splitting.
DRAG & DROP
The core of the feature is the dedicated splitting page. Here, supervisors can choose from multiple methods depending on the order’s complexity:
​
-
Even Split: for fast distribution
-
Split by Item: for more structured division
-
Manual Split: for full control and fine-tuning
​
The interface is built for speed and clarity, allowing quick adjustments, easy edits, and smooth worker assignments.
CONFIRM SPLIT
A clean visual summary of all sub-orders lets supervisors confirm every item is properly allocated before submitting, ensuring accuracy and reducing the risk of missed or duplicated work.
OMS PROJECT
Inventory Management
Factory supervisors are responsible for raw candle inventory and the supply of wax tanks. The interface prioritizes clarity and ease of action to support quick, informed management decisions.
RAW CANDLES
Supervisors can quickly check quantities, availability, and capacity, and submit requests as needed. Inventory is organized by priority levels and colour-coded to surface candles needed for active orders.​
WAX TANKS
Designed to provide a concise and informative overview of the 45 coloured wax tanks along with their status levels. Tank statuses can be manually adjusted by supervisors, triggering alerts to workers and putting all related orders on hold until the situation is resolved.
PROJECT RESULTS
Developing a user-centered solution for real factory conditions
The redesigned OMS replaced manual morning organizing, handwritten tracking, and word-of-mouth communication with automated scheduling, documented workflows, and clear priority sorting across all order channels. Supervisors no longer spend hours preparing tasks or mediating worker conflicts; the system now assigns and splits orders automatically and transparently.
​
By simplifying workflows, adding guidance and error-prevention patterns, and designing for users with low tech comfort, the app significantly improved factory efficiency and accuracy. The result is a dependable, easy-to-use operations tool that supports supervisors, workers, and backend management alike.
