Here at ARIS BPM Community and ARIS BPM Blog, one would expect that we all have a common understanding what ARIS stands for. However, the term “ARIS” is like a chameleon, changing its meaning constantly depending on the context it is used in.

Those different meanings are all correct, but let’s try to be more precise.
