The elephant in the room is Evaluation – as per the ADDIE Model of Analysis, Design, Development, Implementation, and Evaluation.

Granted, this is usually applied as ADDIE; but there is a strong case for applying it as ADDEI; where the necessary due diligence and checks other than fit and proper are performed prior to trade and roll-out.

If you are a training material broker, it would be irresponsible for you to trade in content that is not Subject Matter Expert (SME) vetted and checked for plagiarism and/or a lack of proper attribution.

It is inexcusable and unfair for the third-party client to have to discover what they have purchased in good faith from a reputable material trader, is in fact suspect or dodgy.
