The core competence of any business or group refers to activities which one is really good at. Business research suggests that success at work requires focus. Any working day can be divided into list of tasks most crucial, less so and least. Also a day may be divided into time consuming tasks, less so and least. However the two panes may not align simply because a time consuming task does not necessarily imply importance. Behaviour towards work similarly needs to follow as per the way work is to be driven.
