In my case, the aspects that I liked the most and those that were the most challenging go hand-in-hand. I enjoyed the fact that, to design an energy management system that serves the organization, I needed to work closely with other colleagues – both the experts from other parts of the company, as well as those local colleagues that will be executing the system in the future. I liked this variety and the interpersonal nature of the project. At the same time, making arrangements when there are many stakeholders from different departments is challenging. Some cases resulted in delays and complications, which hindered the progress of the project. Other than that, I greatly enjoyed the seamless interplay and synergy between learning theoretical principles and practical application.
