Various time-motion study techniques have been employed on construction job sites in an attempt to upgrade labor productivity. The five-minute rating technique is one of the methods used to record on-site labor performance. It is a technique that records meticulously each crew member's activities for a short cycle of time, in order to disclose the workload of each and every crew member and the work arrangement of the entire crew. By doing so, the management is able to study and analyze the current work method in the hope of increasing crew efficiency. The processes of recording, compiling, and reporting of the five-minute rating data, however, are tedious operations and prone to human errors. Microcomputers, especially portable microcomputers, may be useful in assisting management in manipulating rating data. This paper introduces the Microcomputerized Five-Minute Rating (MFMR) program that was designed to complement and improve the five-minute rating technique by employing the microcomputer in recording, and consequently in compiling, analyzing, storing, and reporting the five-minute rating information.
