In DMN a decision is deliberately defined very broadly …
“a decision is the act of determining an output value (the chosen option), from a number of input values, using decision logic defining how the output is determined from the inputs”.
Decisions in DMN can be automatic, they can be used for detection, the logic they use can concern the violation of constraints; I see no problem with any of this.My Response
A customer that has placed an order must have an assigned agent.
An agent servicing customers who have placed orders retires and moves to Florida (this last part irrelevant). What “decision” is it that says, hey, now have some unrepresented customers and somebody ought to do something about it ASAP?? What “decided” there are now violations?? … “Detection yes”, “decision” no.P.S. That definition of decision seems a bit circular. To know what a “decision” is I need to know what “decision logic” means. But since “decision logic” says “decision”, seems like I need to know what “decision” means. Hmmm.
I can’t see how you can object to the idea that decisions can be automatic, or used for detection, unless you maintain that decisions can only be taken by people?My Response Putting theological questions aside, in the beginning there was man. Well, people. Well, animals and people. As far as science is currently aware, there is nothing else in the universe that can “decide” something. Well, let’s put quantum mechanics aside. How things get “decided” there is just plain weird. That’s not human scale anyway (as far as science is currently aware). My point is that the concept “decide” makes absolutely no sense unless you acknowledge that “deciding” is a human concept. People decide stuff (or decide when things have been “decided”.) When Machines “Decide” Can machines “decide” things? Of course. Can they often “decide” things better than humans? Of course. Can they often “decide” things instead of people? Of course. Would you call what it is the machines do in such cases “deciding” if there were no people who could do the thing we call “deciding” in the first place? Of course not. “To decide” is fundamentally a human characteristic. If you try to remove the “human” sense of “to decide” from the verb, it’s not how the average person would understand it. This sense comes across clearly in the real world definition of “decide” [MWUD]: to dispel doubt on. When Machines “Doubt” Can machines “doubt”? I’ll let the philosophers decide that (yes decide). I’ll just say this: I doubt (yes doubt) it would be called “doubt” unless people experienced “doubt” in the first place. So when you use the word “decide”, even for what machines are doing, use it for things that people would call “decide”. If you want to use the word “decide” for machines in some other way – for things that people wouldn’t call “decide” in the real world – then please, just plainly admit you’re in systemland, not in peopleland.
“Under DMN we would say that the automatic detection of the violation of a constraint is indeed a decision.”My Response … Which part of any definition of any of the following terms in your statement would in any way, shape or form lead to the notion of “decision”?!
