Work Measurement / Sampling

Work measurement/sampling is the determination of the difficulty of a given task by using both physiologic & biomechanical parameters to evaluate compatibility of available motions with motions required to perform the task. So why would anyone care about this?

Determining a task's parameters can benefit organizations seeking profit by:

Cost accounting
Evaluation of alternatives
Acceptable day's work
Scheduling
Pay by results

Common Methods of Determining Time per Job:

Stopwatch time study (sequential observations)
Occurrence sampling (non-sequential observations)
Standard data
