management, command and supervision are the main functions of management. All of them are clearly related to decisions in order to implement the plan and to set goals (Deisler ,2010). The decision-making process is the major issue that gets a lot of attention by the manager and occupies a large portion of his activity. It is associated closely with the function of planning, because the activity of planning itself is to make decisions (Alsahen, 2000). According to (Alhelo , 2000), decisions are classified according to the level at which decisions are taken: Strategic decisions: associated with goals and master plans of the organization and relatively cover a long period of time.
