Definition
The units were actually in bulk operation; the materials were given eight self-checks, including "unit width > 5 feet " .
In detail
Fake Flow refers to the phenomenon of appearing to be arranged into cells on the surface while still operating in batches in reality. It addresses how to identify whether cellularized production truly achieves one-piece flow. Compared with true Flow, Fake Flow is only a change in form, with no substantive Flow improvement. The textbook provides 8 self-check criteria, such as a cell width greater than 5 feet. The output is a diagnostic result and improvement direction.
Example in practice
Inspecting an already built cell reveals large amounts of Work in Process piling up between stations, with operators processing multiple pieces at once. Using the self-check criteria, the cell width is found to exceed the standard and material Flow is discontinuous. After confirming it is Fake Flow, the processes are rebalanced and batch sizes reduced so the cell truly achieves one-piece flow.
