I've to be very honest that I was overwhelmed with work. I had very little time to offer to students working on my project because it's very time consuming, and not always worth. Luckily that I've give this group a chance because their work will have an impact on my business. They required very little supervision. It was like working with professional. Their findings and suggestions have been well thought and relevant for the size of my business thanks to professor Lenny clear guidance.
