Time Study and Design

Abstract

This paper describes new basic principles that underline the successful application of time study in ergonomics. The main purpose of time study is estimation of time required to perform a task. Often, time for task performance is based upon actual performance studies in which measurement are taken. Time not only reflects the duration of human performance and the distinguishing features of external behavior but also specifies internal cognitive processes. The time study becomes particularly important in those professions that have time restrictions. The presented material can be used not only for studying human productivity and effectiveness of human performance but also in ergonomic design.
