Do your team managers or members struggle to lead their team or colleagues? Or do you find that they often need too much involvement from you for strategic planning? Do they constantly come to you for approval or to make a simple decision? These signs could tell you that your team lack (or not empowered enough to exercise) their conceptual skills.
When trying to identify the areas you want to develop your team's skills in, be open-minded and look outside the box. Limiting your options to just job-related skills can risk missing important conceptual skills that could empower your team and increase productivity.
