A Predetermined Motion Time System (PMTS) is an approach to work measurement where the observer collects data by videotaping each task performed correctly once. This observation is then broken down into a step-by-step process, where the time it takes to perform each step is extracted from a database of time values that have been validated over decades of careful study and analysis. The result of this work is a labor standard.
The PMTS approach to developing labor standards is dramatically better than a stop-watch time study because labor standards can be developed much more quickly (tasks only need to be observed once) and the resulting standards are significantly more accurate (time values are not affected by the skill level or mood of the observed employee).
