Product Change Event
A product change event occurs when a production unit starts to make a new product. The event occurs at a discrete point in time, but it identifies a continuous run of a specific product from the time the previous product change event (start time) occurred to the most recent one (end time). Product run statistics can be automatically captured for each product change event type variable following the trigger of the event by using this start and end time for the product run.
A production unit is limited to a single product change event because, theoretically, only one type of product should be produced on it at a time.
