The extent of work that has already been undertaken - for example, the extent of trading, partners identified (who are they?), is the system at the trialling stage or still developing?
The EDI invoice message standard (TRADACOMS, SMMT/ODETTE, EDIFACT or other) and check that the version in use is in line with departmental requirements
EDI translation/deformatting, for example in-house standard to EDI standard and vice versa - what software is used, for example an EDI enabling package, Interbridge or in-house software?
Control procedures, especially in relation to departmental requirements.
