“[…] you learn that you are not alone in dealing with a technical problem and sometimes you just need a second technical opinion. Sometimes, it does help if you listen to people who see it from a totally different perspective. To give you an example: [suppliers] are the providers of equipment and we are the demand side. There sometimes are good discussions to come to a common solution, which you don’t get if you sit at your desk […]. This sharing of technical knowledge as well as brainstorming around the technical problem with different stakeholders who see the problem from different sides, I find that really refreshing or rewarding. But that again, this is not formal training or whatever.” Photo: Christakis, N.A., Fowler, J.H., 2009. Connected: The surprising power of our social networks and how they shape our lives.
