The WMS CATALDE Pocket is a mobile extension of the SAAS tool, developed to optimize warehouse management directly from the phone. This case details the development and implementation of the mobile application, which acts as a data collector for various critical system functions, providing greater mobility and efficiency for warehouse operators.
Context and Problem
CATALDE identified the need for a mobile solution to enable warehouse operators to manage their tasks more efficiently and quickly without relying on fixed stations. With the increasingly dynamic market, the ability to manage warehouse operations from mobile devices has become essential.
Project Objectives
• Provide a mobile solution that allows warehouse tasks to be managed directly from the phone.
• Increase the efficiency and accuracy of daily operations for warehouse operators.
• Reduce the time and effort needed to complete receiving, picking, and replenishment tasks.
My Role:
As the Product Designer, I was responsible for all research and interface design.
Design Process
Research Methods: Benchmarking, Análise Eurística e Desk research
Sketches and Wireframes: Low-fidelity sketches and wireframes to explore different layouts and navigation flows.
Design and Iteration:
• Prototypes: Interactive prototypes in medium and high fidelity to test the usability of the application on mobile devices.
• Usability Testing: Usability tests with warehouse operators using Maze, focusing on ease of use and workflow efficiency.
Wireframing Process

The login screen should display the app logo along with the login and password fields to be filled in by the user. It also includes the access button.

The home screen with a navigation menu to the other screens. It should be divided into quadrants with the icon and the name of the screen it directs to. There will be a welcome message with the user's name at the top of the screen.

The user will be directed to the address reading screen if necessary.

Invoice List: This screen is exclusively a list where the user will select which invoice they want to store.
Invoice Product List: This screen shows which products are linked to the invoice, and the user will select from the table the product they wish to store individually. It includes a button to finalize the storage of the invoice.
Product Detail: This screen allows the user to fill in the quantity field for the product they wish to store.

Balance Inquiry: This screen allows the user to fill in the product field and select the center through a dropdown list.
Balance Details: This screen will have cards to display the product description, total available quantity, available physical quantity, and reserved quantity. Additionally, it will show lists of addresses, requisitions, and movements below. These lists should be in collapsible cards for better information distribution on the screen.

Screen displaying a list of products, preferably within an expandable card that will show the fields: Quantity and Address.

This screen will have cards to display the number of products recorded in the 1st count, 2nd count, 3rd count, and closed counts. There will be an exclusive card for products with the status of Closed and In Progress, showing how many products are recorded in the 1st count, 2nd count, and 3rd count. The Overall Progress card will have a list of progress bars representing the progress percentage of the inventories for each distribution center (DC) and all DCs.

Product Listing Screen: This screen will first show the next orders in the user's queue in a card. Then, it will display a table with the columns: Address, Product, Center, and Quantity. When clicking on a product, the user will be redirected to the Product Detail screen.

Product Detail Screen: The screen displays the order number, center, and product description in a separate card. Then, there will be two cards, one to show the address and another for the available quantity for picking. Below, there is a text field where the user will fill in the quantity they wish to pick for the product.

Solutions and Implementation
Final Design: The final design of WMS CATALDE Pocket features an intuitive and responsive interface with clear icons and optimized workflows for mobile devices. The main functions (receiving, picking, replenishment, etc.) are easily accessible through a simplified menu. 
Collaboration with Developers: I worked closely with the developers to resolve specific technical challenges for mobile devices and ensure a consistent and efficient user experience.

Challenges Faced: One of the biggest challenges was ensuring that all critical system functions could be accessed and executed efficiently on a smaller screen without losing usability.

Professional Growth: This project allowed me to deepen my skills in mobile application design and strengthen my ability to conduct research and usability testing in high-demand operational contexts.
