What is instructional design?

What the discipline covers

Four questions do most of the work. What should the person be able to do afterwards, stated as an action rather than a topic. What do they already know. What is the smallest thing that closes the gap. How will you know whether it worked.

The last one is where most operational training quietly stops. Delivering the material and confirming attendance answers a different question from whether anybody can now do the thing.

The models, and what they are for

You will meet ADDIE (analysis, design, development, implementation, evaluation) and iterative alternatives such as SAM. They are project structures, not theories of learning. Their value is that they force the analysis to happen before the writing and the evaluation after the delivery, which is exactly the order most organisations reverse.

Treat them as checklists rather than methodologies. A model that adds three weeks to a procedure change you need on the floor on Monday has cost more than it returned.

Where it earns its keep

Two things, mainly. Cutting scope, by separating what a person must know to do the job from what is merely true and in the manual. And sequencing, by putting first the thing that makes everything else make sense. That is why a well-designed five-minute module can outperform a thorough forty-minute one: the difference is not production quality, it is what was left out.

Nobody in your operation has this job title

A multi-site operation almost certainly has no instructional designer, will not hire one, and its site managers will not become one. So the useful question is how much of the discipline can be built into the process instead.

None of that requires expertise. It requires the decisions to be made once, centrally, and not re-made by every author. The guide on knowledge checks that actually stick covers the check itself.
