Indirect Labor Analysis
Indirect
Labor Analysis differs from Direct Labor Analysis by the method
of study. Conventional methods or tools such as time study or
pre-determined time measurement will generally not work. The indirect
work is usually composed of work that is long cycle, non-repetitive
and without definite starting and ending points.
Usually a method or combination of several methods must be chosen.
The selection of one or several of the following techniques is
usually made: Work Sampling, Group Timing Technique (GTT), Time
Study, Operational Audit and statistical analysis consisting of
Correlation and Regression Analysis. The choice of the technique
is extremely important and must give full consideration of the
measurement accuracy required, the relative cost involved and
the requirement for truly representative results.
