2-shut down is necessary if there is big change in the method of work or manufacturing ,if shut down will carried  a large scheduling efforts will be engaged together for several departments in order to handle the maintenance during the shut down special feed back team must be exciting to help focusing on the work which is going on during the maintenance  

3-maintenance  is divided into three basic categories(preventive ,corrective,periodic) and one special category is(predictive)
