A programme is decided in its second month.
The first month is easy. Everyone is interested, someone senior is watching, the first groups go through. Then the work turns up: a unit stops working, a second site is added, a new starter needs what the others already had, and somebody upstairs asks for a list.
In most companies all of that lands on one person, on top of the job they were already doing. That is where programmes quietly stop — not because the training failed, but because nobody had the hours. So the question worth asking is not what the training does. It is who does the rest.
