Processes 
A process describes a manufacturing technique such as drilling, turning or assembly. A process groups together all the methods and the corresponding value types that can be used to calculate standard values for a production technique.
In one process you can:
evaluate several different methods and so several different standard values or
evaluate a method several times, add the results and transfer them to a standard value or
evaluate several different methods, add the results and transfer them to a standard value
Example
You can assign the methods "drilling", "reaming", "countersinking", "threadcutting" and "setup" to the process drilling and so determine several different standard values.
The value type for the method determines which results are added together.
Processes are assigned to the work center where the technique can be used. If you want to carry out a standard values calculation from within the routing, then you must allocate at least one process to the work center for the operation.
