A time study was performed on a process that consists of the following elements: operator removes a machined part from a milling machine (and sets it on an inspection bench), the operator then adjusts machine for the next milling cycle, loads the machine with the next part and starts an automatic cycle, and finally inspects the previously completed part (while the machine is running. Times are in minutes. Note the observed time has already been calculated into a "normal time" NT, so no performance ratings are given or necessary. Allowance %'s for each element are provided in the table.

In the "Calculate Standard Times" group of questions, you will enter the standard time calculated for each of the 4 elements from the table below.

Question: Enter total expected cost (TEC) for N rounded up (the higher machine count of the 2 alternative)
