Work study is the systematic investigation of human work in all circumstances, including techniques, method studies, and work measurement. Its importance lies in improving productivity, removing waste operations, establishing accurate time standards, and contributing to the organization's profit. The procedure involves selecting the job, recording data, examining the data, developing an effective method, estimating standard time, defining the new process, installing it, and maintaining it. Work study helps achieve smooth production operations, minimize product cost, maintain good working conditions, and develop a better work layout.
