Additionally, recent research regarding how local governments are addressing human factors and safety issues related to electric scooter sharing systems will be presented.

Abstract: Industrial engineers have been timing workers for decades to set work standards and measure performance. Lean manufacturing, as well as wage and hour litigation, has renewed interest in time study and work sampling. This presentation will describe examples of time study questions that have emerged as workplace issues and conditions have evolved. In light of these questions, the long-standing issue of the potential for observer effects on the validity of time study and work sampling data will be addressed. In this presentation, the speakers will share
strategies, techniques, equipment, and software that can be used to address potential observer effects.
