I disagree with Scott that the PM did not have responsibility for these after turnover needs.
For a successful project, the operational, maintenance, training to lable a few are task the PM must absolutly have listed to be accomplished. These are task that would normally be started way befor the project is ready for turnover.
The progammers, and others develop Help Desk - Issues, the trainers work with the programmers to develop the training content, and other like issues can be documented and be made the responsibility of an operational person or team to prepare for their operation needs.
Note: this combo practice produces a more skilled operational team who grows with the project.
If this is done the real return on the project can be realized, by the successful operation the project by the persons who have to run it and those that receive the right information.
Each of my projects over 20 years have been performed in this manner with 100% success.
As for formal guidelines for this practice please refer to 'Project Management Insitiute' (www.pmi.org)'s PMBok - Project Mannagement Book of Knowledge an ANSI Standard.
