One-Piece Flow

One-piece flow is a lean (manufacturing) practice, in which customers receive a valuable product that is produced from start to finish, per the customer's needs. Such a process limits work-in-progress, eliminates waste, excess processing, and over-production, which increases efficiency and lowers costs.

Due to reduced work in progress, the flow of the value increases, overhead costs go down, the inventory carrying costs signifiacntly reduces, the throughput increases.
