In any given field of study, there is Perfection and Reality.
Let’s say you’re talking with a recent PhD graduate in Sub-Molecular Omni-Buzz (2.0), and you have a simple question.
You: “How do I get my sub-molecules to buzz, omni-wise, 2.0 times?”
PhD: “Well, technically, you’re supposed to read the manual, close all other applications, don your safety glasses, and most important, do not attempt to rock the machine.”
You: “Hmm, that sounds pretty complicated.”
PhD: “Actually, you can just unplug the Omni-Moleculator, wait 10 seconds, and plug it back in.”

Clark Aldrich has a great post about the difference between Math as a Perfect science vs. Math in the Real World. It’s true, Clark says, that one and one equals two.
1 + 1 always equals 2. Isn’t that perfection? It seems like it. [But] if I combine two piles of hay, what do I get? One pile of hay!
The same goes for Training in the Real World.
When companies do soft skills training, for example, they can apply Perfect World principles. They can use the right blend of study, practice, discourse, and testing. They can even throw in a wiki and a podcast and everybody’s thrilled.
Training in support of change management on a major change, like a software implementation, is closer to the Real World (Sorry, HR training departments; I’m exaggerating for effect).
For example: Company A is installing Big Hairy Software package XYZ (or should it be called ERP?). They’re spending $2 million on the software, $8 million on their Big 4 system integrator, and taking 20 people out of their regular jobs to work full-time on the project for a year.
So, with a monthly burn-rate of $1 million or more, training takes on a new flavor. Is there really time to let learners practice (what the heck is the ROI on practice, anyway?). A Wiki? That would only facilitate rumors and mis-information (or would it?). The fact is, we don’t know.
Of course, I know that theory has to run a few years ahead of practice. It has to be perfected in the lab before it can work in the real world.
The trick is to somehow use a solid, blended learning approach in the context of a costly, time-crunched change effort. That might mean backing off on the Perfection a bit, and striving for a tolerable Reality.
