One Piece Flow is one of the key elements with which an organization can become lean. To think of processing one unit at a time usually sends a shudder through the organization which has batch manufacturing as its life blood. The word “one” does not mean one in the literal sense but in terms of customers’ requirements. In this sense, it means that the organization only process what the customer wants, in the quantity he wants and when he wants it.
One piece flow is simply a methodology for manufacturing components in a cellular environment (an area where everything that is needed to process the part is within easy reach, and no part is allowed to go to the next operation until the previous operation has been completed).
The goal of one piece flow is to make one part at a time correctly all the time without unplanned interruptions and lengthy queue times.

Comparing One Piece Flow & Batch Processing
While One-piece flow describes the sequence of product or of transactional activities through a process one unit at a time, batch processing creates a large number of products on a large number of transactions at one time – sending them together as a group through each operational step. The focus of One-piece flow is on employees’ efforts on the manufacturing process itself rather than on waiting, transporting products, and storing inventory.
It enables the production process flow smoothly, creating a steady work-flow for all employees involved. One-piece flow methods best functions with short changeover times and in a pull system environment.

Advantages of One Piece Flow
There following are some advantages of incorporating one piece flow method into work processes:
- Helps reduce the time that elapses between a customer order and shipment of the finished product.
- Helps prevent the wait times and production delays that can occur during batch processing.
- Enables reduction of excess inventory, one-piece flow thereby saving the labor, energy, and space that employees would have devoted to storing and transporting large lots.
- Reduces the damage that can occur to product units during batch processing.
- It helps reveal defects or problems in product units early in the production process.
- It provides the organization flexibility required to meet customer demands for a specific product at a specific time.
- It enables reduction of operating costs by making non value- added work more evident. This enables you to eliminate waste.
