Cellular Processing is an approach in which equipment and workstations are arranged to facilitate small-lot, continuous-flow production. In a manufacturing "Cell," all operations necessary to produce a component or subassembly are performed in close proximity, thus allowing for quick feedback between operators when quality problems and other issues arise. Workers in a manufacturing cell typically are cross-trained and, therefore, able to perform multiple tasks as needed. Cells also work well in office functions.
Single-Piece-Flow can be described as an ideal state of efficient operations, where batch sizes and lot production are replaced by working on one piece at a time. It is a Lean Enterprise goal to achieve single-piece flow in every operation where possible.
The perfect process consists of a single object transitioning through a series of operations while constantly accumulating value that the customer is willing to pay for.
Typically, the methodology is applied within manufacturing operations but works equally if not better in administrative processes. The problem in administrative processes is that batches are often hidden electronically.
