Hi, I'm the PM of a training stream on a system development project. We have a large community of end users that need to be trained (500+). As an Agile development project, we don't have design documents to develop our training material from. With a fixed launch date and development slipping, we have lost the time we had scheduled between system completion and go live for completion of training materials.

Does anyone have any suggestions on how to develop training materials for end users for a system that hasn't been completely designed or developed. We are struggling with this. Thanks.
