SAP,
Hmmm. If you can't prepare such a presentation from your own experience and knowledge, you are probably not the right person to be submitting this to the client.
What makes you think that the client will actually benefit from APO? For some clients, this package of solutions does not make sense, and implementing it is a waste of his time and money. How do you know this is not one of those clients?
Don't get started on the wrong foot with this client by trying to present other people's work and passing it off as your own. If you don't already have a good confidence, based on experience, of how the client will benefit from APO, and supported by your OWN war stories, you probably shouldn't be making this presentation at all.
Best Regards,
