I recently joined a webinar discussing Effective Engineering Leadership. One of the questions was around remaining current as an Engineer when making the change to a management role.
My advice here is to think about the job that you want to do, and focus on that. You need to make a choice between the Individual Contributor role and the People Management role, as they are different jobs with different skillsets.
You can trial one or the other for a period of time, but if you try to do this for a long time, you’ll just end up doing two jobs badly, which is not a great outcome.
On either path you can still be a leader, and in fact that’s expected as you progress and grow your career. Good organisations will support this and have development paths for both tracks. Bad ones will force their best ICs to management. Choose where you want to focus your efforts!
Nothing is also a choice, but in your career doing nothing and just drifting along is likely not a good one.
So pick a role, understand it, learn the skills you need to be successful and deploy them. Don’t do two things badly.
