Given the information concerning Cellular Manufacturing, Is it possible to have a cell within a cell?
ie. An engine building cell splits personnel and creates an engine testing cell within the original cell.
While it depends on the company and how they want to organise their production and process design, it's likely that tests would performed on each main component of the engine (making sure holes are the right sizes etc) and then a final test would be performed at the end of the cell flow.
In addition, spot checks would occasionally be performed by production managers so I doubt that a separate cell for testing would be needed.
It is, of course, possible to have a cell within a cell but the idea of cellular manufacturing is to have a pool of workers who are trained to produce most products in order to promote flexibility (in case somebody took the day off).
Having an isolated cell as you suggest would go against this concept and cause problems if the person testing components suddenly fell ill.
This is my experience from working in a small company producing precision-manufactured massage devices.
