“Good factories develop beginning with the 5S’s. Bad factories fall apart beginning with the 5 S’s.”

Using Departmental Specialization (Job Shop) for plant layout can cause a lot of unnecessary material movement
Note how the flow lines are going back and forth
Revising by using Group Technology Cells can reduce movement and improve product flow
Suppose we operate a production plant that produces a single product. The schedule of production for this product could be accomplished using either of the two plant loading schedules below.
Not uniform Jan. Units Feb. Units Mar. Units Total
1,200 3,500 4,300 9,000
Uniform Jan. Units Feb. Units Mar. Units Total
3,000 3,000 3,000 9,000
How does the uniform loading help save labor costs?
These are small specialized plants that limit the range of products produced (sometimes only one type of product for an entire facility)
