Toyota is a low-mix high-volume manufacturer of a limited variety of similar assemblies. Compared to Toyota, would you say that you are a high-mix low-volume manufacturer of a large variety of dissimilar components?

Yes

Several performance measures, such as Order Flow Time, Inventory Dollar Days (Work-In-Process Inventory) and $ Shipped per Day (Throughput), focus on the speed with which an order is shipped to and paid for by a customer (Cash Flow Velocity). Now, Lean recommends to focus on the elimination of the Seven Wastes (Overproduction, Waiting, Transportation, Over-processing, Inventory, Operator Motion and Scrap/Rework). Can the impact of Waste Elimination be measured using Cash Flow Velocity?

Yes

Does your product mix consist of 100’s, maybe 1000’s, of different components whose routings are dissimilar?

Yes

If you answered “Yes”, have you analyzed the product mix to find the groups of components with identical or similar manufacturing routings (aka “component families”)?

Yes

Creation of flexible work instructions for an entire part family
