A few things that seem to be missing for me. Granted, they may come out in discussions, however, they need to be in there right at the start IMHO, (not in any particular order...)
1> Is there any reason why this needs new "training" per se - have you checked the existing resources?
2> Why are they getting it wrong? (This is slightly different from "Why do they need it?", and aims to try and tease out, for example, that they do not need more training, they just need the existing Induction training to be amended...)
3> Who is the ultimate sign-off for this training? (Often the ultimate signatory eventually gets contacted, and does not sign it off, leaving a budgetary sh1*storm. Best to warn them upfront of your intentions!). **NOTE - this person may not be the same as "Approval Authorisation". You need to be sure of the FINANCIAL chain of command rather than just the Chain of Command. Just because there is a "Training Budget" does not mean that the person in control necessarily wants it used for this...
4> Need much stronger measures of success in my opinion. Link it to increased revenue, reduced loss, reduced business risk $s etc. All training has a financial measure (or should have), it;s not about "...what they can do differently...", that's a given. It's about "What positive $ difference will this investment make to our business?" - and how can I prove that it has happened.
Just some thoughts.
