The research
People moving into management for the first time should be the rarest breed of people ever. If the stats are to be believed and there are multiple pieces of research to show this, 50% to 60% of first-time managers fail. How and why would you ever want to take on the role as a first-time manager if you knew that 50% to 60% of those people failed in their new roles. This is especially troubling when most likely, as an individual contributor, you are already a Rockstar.
