      Key role in the development and roll-out of pre-sales software for the Vaillant Group. As a junior planner, I was able to support the successful launch of a new product group through a roll-out of planning software, created and delivered planning training, and provided second level support. The focus of this study was on building technologies in particular on renewable heating, cooling and power supply. Due to the integrated practical phases, I was able to gain a lot of insights into different areas of the company during my studies, such as development, purchasing, sales, pre-sales and other departments.
