Pan And,
I do not think we will find a standard that defines what must be included in a Work Order/Traveler. This is because a QMS has so many choices in how to document the items I listed above.
If processes are automated, there is little need for a Work Order/Traveler. Organizations that do production work on an order-by-order basis (sometimes called "job shops") may have more need for Work Orders/Travelers. However, even then the detail can be affected by what the drawing/specification says and how procedures are made available to process people - and the details those procedures include. Duplicating information is not something I support unless it helps the organization study what took place or some other useful purpose. Some organizations don't even like to record which instruments were used to inspect, claiming the instruments are traceable by their being assigned to their users.
If the customer requires a Work Order/Traveler to list specific information, that is a requirement. Other than that, the organization is responsible to determine how process information is being managed.
