Most organizations are pretty good at creating training. The real struggle is delivering it consistently.
You can have solid content, good slides, and clear objectives and still end up with very different experiences depending on who is facilitating, how much time they had to prepare, and whether they have run the session before. That inconsistency usually gets blamed on facilitators. In reality, it is almost always a delivery support problem.
A strong facilitator guide is one of the simplest ways to improve instructor-led training. Not because it makes training more exciting, but because it makes it easier to repeat, easier to scale, and more likely to work.
