This synthesis reviews use of standard maintenance job times (work standards) for transit bus maintenance. Work standards, a set of objectively based criteria for measuring the adequacy of work performed, are used by 20 of 50 U.S. and Canadian agencies surveyed. Most standards programs cover the full array of bus hardware systems. Types of work typically standardized are inspection, preventive maintenance, corrective maintenance and unit repair. The least attention has been given to troubleshooting. Computer technology is starting to be used to support work standards programs, although capturing performance data at its source has received little attention. Time-oriented work standards are based on the assumption that each job is done properly, an assumption to be verified by quality control. Standards are most often based on in-house historical data, augmented by some data from external sources. Time-and-motion study is seldom used to set standards in the transit industry. Work standards are used to identify problem areas, establish work schedules and for monitoring of personnel performance. The work standards program of the Chicago Transit Authority and of Metro Transit of Seattle have the most extensive documentation. A 9-step process for establishing bus-maintenance work standards includes: Definition of all jobs to be covered, standards to be used, establishment of data handling system, data collection and reports, evaluation of job performance, improvement of job performance, establishment of time standards, establishment of accuracy standards and updating of work standards. Work standards must be kept current if they are to retain credibility.
