Hello community,

Is it only allowed to use the "process interface" symbol at the start/end of an epc model, or can i also use it in between a model to show a process, that is "outsourced".

 

with the attached epc model it want to show, that:

1.) We produce a product

2.) Send it to a provider, which does the quality check for us (that is the process interface/outsourced process)

3.) Provider sends it back to us

4.) We send the product to our customer

 

Is this a correct model, or isn't it allowed to use the process interface symbol this way?

 

Thank you very much in advance,

 

BG André
