Methods Time Measurement ( MTM) :
In this method predetermined time values for basic motions or therbligs such as reach , move turn apply pressure grasp position release and disengage etc. Are established in terms of TMU ( i, e, time measurement units) one TMU = 10 5 hour or 0.00001 hour or 0.0006 minutes or 0.036 seconds. the time values are listed in tables in terms of TMU for basic motions and may be applied to any type of operations that may be resolved to the basic motion thus eliminating the use of stop watch.
Application of MTMs techniques
a. Developing effective methods in advance of beginning the production.
b. Improving existing methods.
c. Establishing standard time data .
d. Estimating labor time and cost.
e. Training supervisors to be method conscious.
f. Choosing between alternative methods.
