I found some time to test the EPK validation features of ARIS Express.

 

Please take a look at the two flows below.



 

The left side flow forks with an Exclusive OR (XOR). Consequently exactly one of the two alternative paths is performed. The AND join waits for both paths to be finished. This flow cannot end. ARIS Express gives no warning or error message. Nothing!

As  far as I understand EPKs a state cannot fork. Please correct me if I am wrong.  Here again ARIS Express gives no warning or error message. Nothing!

Further more, I drawed both flows in the same single diagram. No warning about duplicate names. Nothing!

I consider this as an absolute show stopper. Visio or Dia -- to name a free of charge OSS tool -- provide me the same functionality.

What is the aim of ARIS Express?
