Continuous Flow
Continuous Flow Defined
Operations are continuously flowing when product is pulled from the previous operation as it is needed. Only quality parts are allowed to move to the next operation.
Advantages to continuous flow processing include shorter lead times, minimum or no work-in-process inventory, and ease in identifying defects and/or problems before they get to the customer.
The goal of world-class organizations is having processes linked with minimal WIP within the main production flow.
Takt time is known and work pace is scheduled according to takt.
Machines and operations are grouped by product family rather than by departments.
Machines are in order of process, reducing waste of motion, travel time, and floor space.
Front office work (i.e., orders, quotes, purchasing, etc.) flows evenly and smoothly without delays.
Continuous Flow Assessment Guidelines
1. Processes Linked Through Value Stream Analysis
A value stream analysis consists of all the actions essential to the product or service, both value-added and non-value-added, currently required to bring a product through the main flow. It includes:
-
The production flow, from raw material into the arms of the customer
-
The office work flow (from concept to receiving payment)
Value Stream Mapping (VSM) is used to visually map a product's production path (materials and information) from door to door. VSM serves as a starting point to help management, engineers, production associates, schedulers, suppliers and customers recognize waste and identify its causes.
2. One-Piece or Optimal Lot Flow
One-piece flow produces and delivers one...
