A couple of months ago I transitioned into the role of data science lead. Suddenly instead of just having to think about how to deliver new solutions, improve operational processes and review contributions I had to also mentor a new team member, develop new team processes and rituals, coordinate and project manage, shape OKRs, and contribute to developing presentations to executives to approve what we were delivering. For a few weeks it was like I was working two jobs; in the day I would either be in meetings or working on planning and communication, and at night I would be modelling or writing code to make sure we could deliver the right solution on time.
