Yes, and no, Hoke.
As far as I know,
SPORH is still the base metric I.E. uses for time studies.
The stops per car metric is a direct result of the pas/edd dogmatic approach.
Dispatch is based on dividing the number of pkg cars into the present volume.
Routes are cut, and, add/ cuts are added to the prescribed number of allowed pkgs cars, without regard to efficiency.
I easily made $15,000.00 last year in excess O.T., do to the incorrect dispatches based on SPC.
I could have done the same amount of productivity for $75,000.00, but for their efficient dispatch, they paid me $90,000.00.
What alternative is worse that blatantly losing money through bad planning?
