TL;DR: An interesting self-reflection on the 1st year as an engineering manager.
This role is not about the tech. It is also about the tech. It is primarily about the people.
Your puzzle is no longer technology. Your puzzle is humans. You have to switch from “ignore-the-human, solve-the-problem” approach to “solve-the-human, ignore-the-problem” approach. So you need to remind yourself to trust your reports that they will solve the tech, the tech is not your job any more.
These are the fundamentals. Everything else is a distraction.
Results means ensuring projects are delivered on time and deliver the desired results, e.g. increased revenue for the company.
Retention means ensuring that teammates are engaged in their jobs, are unblocked in performing their tasks, and that they have challenging projects and career growth.
