What is the difference between an electronic manual or help and a PCS?
Electronic manuals or help systems are no more than books put on-line. Using an on-line reference to assist in performing a task involves locating the desired information (which may exist in several places) in the help system, reading and understanding the procedure, and then applying the procedure using the actual system. In a PCS, the procedure for completing the task is part of the system flow – the system guides you through the procedure, giving or requesting information along the way.
