I work in automation (mostly) as a lead tech and professional troubleshooter because I am familiar with a wide and varied amount of automation technologies. I've met plenty of people over the years who have much more advanced skills than myself, but never go beyond doing more than parts swapping on a workbench, which leaves me scratching my head.
Over the last few years, I have listened carefully to what people around me say about my work, and while it is good gas for the ego, I have notice that's not the likely reason I get promoted so quickly. While I can walk into a problem and know how to apply different processes to figure out what to do almost reflexively at this point, the real focus seems to be that I take ownership of the process.
Bit of a buzzphrase, "ownership of the process," but the short explanation is that a little planning, accountability, resourcefulness and communication seems to get you a lot further than just knowing what to do in any given situation. Employers like that because they now have department manager they can rely on, and team members like that because someone else is taking responsibility so they don't have to.
You're good at code, obviously, but if you zoom out on your work a bit, are you also bringing a bit of accountable authority to the table? That may be the real reason why you move up so quickly, or at least something that greases the gears so that can happen faster for you than, say, an equally skilled colleague.
