Correcting errors

Simple one-process manufacturing with corrections.

Note that the diagram below shows the actual data in the flow. If a use case calls for it, the events can be combined on a user interface so that a "corrected" event would be displayed, for example just "work 6 hours machining" and "consume 5 plywood sheets" as the two inputs to this process. In that case, you could show all of events, including the correcting events, in another view.
