Inventory Management App






2019 – 2021

About the Project

USCHIS is a small company that has set itself the task of producing sugar-free fruit spreads. Depending on the season, various types of fruit are strained and frozen to be processed into jam when needed. The application is intended to help in the process to store the fruits and provides the user with a simple way of entering relevant product information. In addition, it creates an overview of the stock of frozen goods and already produced jams.

Project Brief

USCHIS is in need of an Application that helps them to keep track of their inventory. It should support their employees during their everyday business. The app should help with the storage and retrieval of the fruits and also provide forecasts that give information about sales figures.

User Research and Personas

I conducted user interviews to better understand how the employees work in their environment and to analyze their workflow. Due to the insights, I gathered from that research, I was able to figure out some pain points and features that would ease their job.

Based on the research, three design personas could be developed by focusing on the employees needs, goals and challenges.


Using the software Figma, I created a high-fidelity prototype that combined all the required functions of the application. Based on the research, the typical work steps were simplified or enhanced with features to create added value for the user.


I tested participants with a high-fidelity prototype. The main goals were to evaluate how well users could register, or find Information to certain Jams and evaluate how fast they were at freezing fruits and adding relevant information to it.

The biggest problem users had was choosing the right freezer and the corresponding drawer when storing the frozen fruits. Some of the words caused confusion and were misunderstood. Some of the users felt that the filtering options within the fruit-details screen were too imprecise.

Overall the Test achieved an average Task time of about 55 seconds and a SUS-Score of 87. The success rate of the respective tasks is 100% and overall 14 issues were found.



Due to the choice of method, connection problems occurred during the remote usability tests. However, the test could be continued after a short interruption.

What’s Next

After the major usability issues were fixed and the solutions were incorporated into the prototype, I would conduct further testing to verify that the implementations achieved the desired results.

Following that test I would do another iteration of the app, where I would also spend more time on interactivity and other features.
