Ha! say I. Call it what you like, computer programming is computer programming.
"What's in a name? That which we call a rose
By any other name would smell as sweet."
Romeo and Juliet (II, ii, 1-2)
Inspired by the great Shakespeare I say that programming, by any other name, still smells of sweat.
Note that I am not saying that rule-based systems are not useful, or powerful, or neat-o. I am saying that translating real-world polices into absolute statements in some rule-definition language is not a common skill and is so similar to most kinds of computer programming as to be indistinguishable.
Dress it up however you like: if you are not good at programming you likely will not be good at writing rules, let alone debugging rule implementations or grasping the cumulative effect of a large rule set on a large and complex application.
I suppose one could divide up computer programming into "predicate logic" and "computer stuff" (RAM, file I/O, databases, communications, etc). Using this division, I can imagine a person who excels at predicate logic but has no feel for the computer stuff, making this person uninterested in computer programming.
If such a person ended up as a business executive instead of a formal logic academic, (or APL programmer) such a person might be quite good at writing rules. That person might even be able to debug her rules, to cope with the often-wide chasm between the abstraction presented by such systems and the concrete reality presented by the working environment. But how many such people can there be in the world? Certainly not several in every moderately sized company in the world.
So when sales people tell you that, at last! you free of the tedium of dealing with IT professionals, finally free of the tyranny of computer programmers, stop and ask yourself this: are you really ready to eat your own cooking?
As every even junior programmer knows, predicate logic in action is rife with unintended consequences which are the inevitable-but-unforeseen results of rules as applied to the real world.
My personal favorite example of this lateness and snow storms. Most or all of our clients above moderate size use Kronos Time & Attendance products. Most or all of our clients, in the frenzied enthusiasm of the original roll-out, go overboard with the rules, often with amusing unintended consequences. One client decided to implement a "better never than late" policy: if its employees were more than one hour late for work, they could not swipe in at all. This was intended to enforce punctuality. I do not know how it worked in that regard, but I do know that when I arrived mid-morning after a large snowstorm, I was greeted with a stream of employees leaving work: the snow had delayed them and they could not swipe in; unsure that they would be paid for the day, they were going home. Not much got done that day, but what did get done was mostly done by upper management, who were exempt from that rule.
In this case in particular, I like the "silver bullet" trope because even though there is no magic solution to the problem of translating human policy into machine-readable form, the problem can, werewolf-like, sudden get very ugly very quickly under the right circumstances.
So see a doctor for medical problems, go to an accountant for accounting and get your rules from a machine-readable logic expert. Or don't, but at least go into your decision with your eyes open.
