10” Distance

Variable Location

Can get very complicated.

There are other MTM and PMT

systems that exists for different

applications

A sort of combination of both stop watch

time studies and predetermined

studies.

Create your own elemental time

standards (EXCEL)

Not as accurate as a pure PMTS, but is

more specialized to fit your processes

The standards data base will save time for

rate setting in the future

Works well for determining the rate for a new style or part before it is produced
