The ability to do a task need not result in optimal performance. What else do you think necessary?no

There are at least two other things that need to be
present in order for performance to be optimized.

First,
the process of performing the task must be organized in an efficient way.  If the steps
of a task are organized inefficiently, the worker will not be able to do the task as
quickly as would be possible if the organization were
better.

Second, there must also be motivation.  A person
who has the ability to do a task will not necessarily perform the task to the best of
their ability.  If they are motivated to perform well, however, they will be more likely
to perform in a more optimal fashion.

These are some
reasons why management is so important.  Tasks need to be well organized and planned and
workers need to be motivated.  When managers do these things, performance is more likely
to be optimal.
