If you don’t know the answer to this question, how can you possibly expect to get any better? If you want to improve and/or excel, you need to ask your boss, your coworkers, and your employees questions like:
What could I be doing better or differently?
How could I improve __________?
Is there anything I could do to make your job easier?
What do I need to do to earn a promotion?
A caveat: If you’re one of the few brave enough to ask questions like these, don’t take every answer to heart. You may well have one employee who thinks you should hold fewer meetings and one who wants more. Only suggestions repeated more than once deserve your attention.
If you try this and don’t get meaningful answers, it means your culture doesn’t support open, honest communications and that’s a problem that needs an immediate remedy.
