Ineptitude is a hopeless lack of skill. Sheer ineptitude, political ineptitude, breathtaking ineptitude.
It is stronger than incompetence in tone because it sounds like a judgement on the person rather than the work. The Latin behind ineptitude means unsuited, so the fault was first a matter of not fitting the task.
