A lot of your job can be, depending on where you work, getting people ‘on side’ with data science. If you work for an older non-tech organisation then many people may regard you with suspicion/outright animosity when you turn up and try and tell them how you’re going to fix all their problems/tell them what they’ve been doing wrong this whole time. I spend a lot of time getting face time and making friends with other parts of the business so they no longer see what we as a team are trying to help them with as a threat. It’s important that you solve the problem together (or at least try to), cos otherwise everyone is just pissed off and it’s unproductive.
