Production flow · The flow map · Element
The operations
Each production step with its cycle time and batch size.
The part
What it is
Cycle time per unit and batch size together determine how long the step blocks the flow, which is not the same as how long it takes.
Changeover time should be recorded here, since it is what makes small batches expensive and therefore drives batch size.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
