Some definitions that might help you with the terminology found in the descriptions of the training videos
Methods-Time Measurement
a predetermined basic motion-time data system for developing effective methods and establishing "fair day's" work standards.
Time Study
an analytical procedure used to establish the best method of accomplishing a task and to establish the "fair day's work" time necessary for an operator to complete that task. The result of a time study is an engineered standard time that considers the performance (pace) rate of the operator during the study, the training required to do the task, and the personal needs, rest to overcome fatigue, and the unavoidable delays inherent to the work.

Rating
the evaluation of the operator's performance related to the obsever's own concept of what constitutes normal performance. The process of rating is done at the time the work measurement study is taken and the rating factor is applied to the observed or selected time to arrive at the normal time for the task.
Normal Time = Observed Time x Rating % / 100
Work Sampling
is used to measure work activity proportions using random sampling. Usually, a large number of instantaneous observations are made at random times of one or more workers or equipment items over a representative period of time. When the study is complete, the ratio of the number of observations in a particulat work activity to the totalnumber of observations in the study yields an estimate of the proportion of total time spent in that activity. Where each observation is "tagged" with its week, day, shift, hour, supervisor, group under the supervisor, and specific opeartor observed. This permits highly detailed reports and associated graphics that illustrate comparative and trend information and present improvement opportunities about the organizational unit being studied.
