I don't think it is for revenue raising to be honest. The money we are talking about is chicken feed in a large organisation.
In the old days the syllabus use to be made by a mixture of backgrounds from engineers through to ex mil Navigators.
This did sometimes give you to much on certain subjects and it more relevant to there experience. But better to much than to little.
Now there seems very little input from people that have actually done the job.
This means that stuff we actually use is missed and attention is focused on stuff that is never used.
