Allow me to clear up some misconceptions some drivers appear to have about time study.
The Time Study Observer is to document exactly WHAT the driver does as it occurs. The only time the Observer is to interfer with what the driver does is when the driver is doing something illeagle or unsafe.
The most important stept in doing a time study comes after the driver's day is completed. This is when the time study is analyzed and a comparason is made between what the driver ACTUALLY did compared to what the driver SHOULD have done by using the proper methods.
The driver who goes to the rear of a house releases a package and then goes to the front door and knock and waits is NOT using the proper methods and will not be allowed the time to walk to the front door and knock. The proper method for a driver release is to go directly to the place the package will be left and return directly to the car.
The driver who parks in front of a stop, selects a package, walks to the stop and delivers, returns to the car, starts up the car and moves 20 feet to the next stop will not be allowed the time for starting and stopng the car. The proper method is to deliver both stops from the one park car position.
The driver who makes several trips into several stops with multiple packages will not be given the planned time for all the trips. He will be given the time for removing a carry aid, selecting the packages, walking with the carry aid, and replacing the carry aid. The proper method calls for the driver to use a carry aid when required.
There are many many more examples of a driver trying to "beat" the time study when the Time Study Observer is along.
However, it is the Time Study Analyst who determines the allowances for the area. It is the Analyst who evaluates what the driver ACTUALLY did compared to what the driver SHOULD HAVE done.
I think you will agree that regardless of what experience the Observer has or hasn't had, the Observer can tell when the driver is driving the car, or is parked and selecting packages, or is walking to a stop, or at the point of delivery.
A qualified Analyst can go over any time study, stop by stop, line by line, and determine if the driver used the proper methods in evey instance. This is how the allowances are determined.
