To add for the poster, the best way to start switching roles or responsibilities is to volunteer for the things that you want to do. Even if you know that somebody else is already doing it. You’re letting your boss know that you have interest in that responsibly and if that person leaves for vacation or the company, your boss will have you in the back of his mind for the coverage or job. When I was a young engineer, I wanted to get more into analysis than design. So, on my own, I did the analysis in tandem with the analyst and we would compare notes at informal review meetings. My boss would see that I had the skills and aptitude and when the next big job that came along and the analysts were overwhelmed, he added me to his analysis team. However, nothing is instant and will take a few months to a year of branding yourself and networking with the powers that be to make the switch in the same company.
