 Idris, when people approach you and say could you give me one tip to become a better service designer, what would you say to them? I think service designers should not just only be able to look at all the details. He or she must have the ability to look at the whole system level so that the bigger job is not just about designing things. The bigger job is like how do we understand all the pieces and create a kind of trade-off so that not everyone is sort of sub-optimizing the system. So it's kind of like a system view. I think that's an important quality in addition to being empathetic and being detail-oriented. More videos like this.
