I'm finding myself in this position right now. For almost two decades I have worked as a software engineer, slowly learning more and becoming more capable at designing and developing software. Yet, we have a significant lack of leaders and managers. I have been asked several times to take on such a lead role, but what makes me great at developing software does not make me great at organizing and managing a group of people. I have tried it - it didn't go well. Those aren't my interests or my aptitudes. Still, management keeps trying to get me to take on these vacant roles just because they know I have done well for them in everything else, but they overlook that they are asking me to do something very different from the thing I have been shown to do well.
