Survey questionnaires: The researcher designed survey questionnaires for assessing the maintenance management system in the company. The questionnaires were prepared in two parts; one for all levels of workers but the second did only for employees from foreman to managers’ levels of logistic, maintenance, operation, and engineering crews. The former questionnaire was distributed to the management, maintenance department and production department. Totally 72 questionnaires were distributed to maintenance department, production department and management, out of which 71 questionnaires were retuned (98.5%). The selection was partially focused and partially random. Department and division heads were deliberately selected. Line supervisors, chief engineers and foremen were deliberately selected. Some workers have been preferred to the response to be in interview form, they were interviewed. Others filled the questionnaire. The second was developed for positions of foreman and above. The questionnaires contained two types of answers. The first type used a normal scale, Yes or No and the second type a comparative percentages which represents scale like best practice, good, some improvement required, fairly major improvements possible , poor major improvements require, extremely poor (none existent).
