assessment factors based on the components of maintenance management along with developing Wireman Model in 8 industries of holding companies with high level of technology. In order to do this a checklist consists of two parts of systematical and technical requirements was prepared based on environmental situation of the company. After several systematic review cycles, the reviewed components were based as the foundation of an ethnic model. Data aggregation was performed using the primary checklists which have been scored based on Cramer's rule. Among the calculated scores, the least amount belongs to "maintenance based on RCM reliability" with 27 and "predictive maintenance" with 33. In fact the results indicate a gap between the existing circumstances and that which is expected. Also, despite existence of quality management system in Pilot Industries, 37.7 standard deviation which is high, does not hold a desirable status which could indicate lack of effectiveness of auditions based on ISO9001:2008 in the field of maintenance.
