TABLE OF CONTENTS This chapter will introduce the uses and methods of measuring work, with emphasis on predetermined time systems such as MTM-1, WF, MODAPTS, BMT, MTM-2, MTM-3, GPD, and MOST. Examples of applications are shown, and the benefits and limitations of predetermined time systems are discussed.
Work measurement is used to develop standard times needed to perform operations. Time standards have traditionally been defined as the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method, allowing time for personal needs, fatigue, and delay. Time standards, work standards, and standards of all types are critical pieces of management information that apply to manufacturing, assembly, clerical, and other work.
Standards provide information essential for the successful operation of an organization:
Data for scheduling. Production schedules cannot be set, nor can delivery dates be promised, unless times for all operations are known.
Data for staffing.
