This thesis reports the development by the author of a job order system for a maintenance department in a Burnaby petroleum refinery during the summer of 1952. The requirements of this system are (1) to provide a practical channel of communication for the planning and control of all maintenance department work, (2) to provide an adequate description and estimate of the work requested, (3) to provide information necessary for scheduling requested work, (4) to ensure the proper approval authorities for all expenditures, (5) to provide information necessary for costing all work done, and (6) to measure the overall efficiency of the maintenance department. These requirements have been fulfilled partially by (1) the establishment of approval authority limits, (2) the introduction of job order and job order memo forms, and (3) the employment of a job order clerk. At present, however, expenditures are controlled only by maximum approval authority limits. It is recommended, therefore, that the services of a qualified estimator be sought in order that costs may be controlled more closely by means of accurate job cost estimates. This method of control, in turn, will provide satisfactory measures of the overall efficiency of the maintenance department. / Business, Sauder School of / Graduate
