The ability to do a task need not result in optimal performance. What else do you think is neccessary?
There are many human traits necessary for optimal performance of a business task, as well as certain business conditions that must be met. The task itself must be clearly defined, must fit into a larger project, must have reachable deadlines and intermediate goals, and must have a function deemed important by the assigned employee. The paths to information, access to higher authority, and reward must be clear. Secondly, the task must be within the employee’s experience, not just formal training, so that there is a sense of confidence in completing each step. Finally, there has to be room for creativity and innovation in completing the task, so that the employee gets a sense of accomplishment and satisfaction. The task must be valuable in itself, and doable inside the time framework called for.
