"All processes must be executable," says the IT guy. "Aren't all processes working? Is there any process that doesn't work," the puzzled business manager asked.
Most of us would have no problem to grasp the concept of a "business process". However when used in conjunction with terms like "process model", "process instance" or even the word "process" itself, the conversation often get very muddy.

This paper illustrates the meaning of the terms when used in different perspectives and how they relate to each other.
