underdo

The complete lack of the ability to complete tasks with the normally accepted level of completeness from an average intellect. Ineffective. Lazy, but does actually perform small tasks on occasion.

Bob, despite many years of experience, was a complete failure at finishing jobs of a high quality. Instead, he would inevitably underdo even the simplest of tasks. He left so much to be completed by others and would always be underdue as well.
