Business processes in large companies like Toyota Motor Europe can often be inefficient. This thesis focuses on the problems with the company's old way of managing test requests for vehicles and components, which used separate Excel files that caused many errors and were very slow to open. The goal was to replace this system with a faster, more reliable and user-friendly digital application. A low-code development approach with the Microsoft Power Platform was chosen because it allows for rapid development and connects easily with the company's existing Microsoft environment. The new system was built using Power Apps for the user interface, SharePoint to store all the data and Power Automate to automate tasks.
