Improving Work Measurement Practice for Method Improvement and Process Design Using Video Analysis

In direct time study, pace rating is an important element to determine time standards. In the literature, pace rating has always been recognized as being most difficult, challenging subjective, and even controversial. Recently, a tool that can compare the tempo of work motions on (real-life) actual videos with the tempo of work motions on a calibrated reference video has been proposed. By adjusting the speed of the reference video, Industrial Engineers can synchronize the motion patterns in both videos and thus quantify the actual pace of the method under study. Although this approach is interesting, there has been little discussion on validating the new proposed way. Current research shows no knowledge and deeper understanding on the usability and limitations of this method. The goal of this research is to study these aspects.

Findings until now

  1. To improve pace rating practice, we have extended the idea of synchronizing the work motions on reference and actual videos by developing a new software that can visualize decision making patterns on pace rating. Documenting the decision making pattern can serve as an aid to communicate more effectively between management and unions. In addition, reproducibility is greatly improved.
  2. Motion compatibility between the reference video and the task under study gives more accurate and precise results for the rated pace.
