“In a business, unit planning is carried out by top level management but its implementation has to be carried out by the employees. All the departments have to work according to the guidelines given by top level management, thus experts are known as brain of an organization whereas staff is considered as limbs. If limbs do not work, then orders given by the brain will be useless and body cannot perform even the routine activity. In the same manner in an organization. If the staff does not carry out their work properly the business would prove to be a failure.
