As part of my Master, I made an Internship at Degrémont as a Production Trainee. In that context, I had first to develop a precise and reliable way to measure plastic tile thickness. I had also to analyse data I collected all along the production line to determine the cause of production waste for a certain type of tile. These projects allowed me to work and collaborate with all kinds of people : I had to communicate with operators in order for them to understand what I was doing and get their help and approval, I had to communicate with the management, to explain how I was doing, where I was in my research. In a Company all the services are interconnected and a good intern communication is really important for the work to be done.
