Waste Waste

The elements of work that add no value.

Waste only adds cost and time.

Things to remember about Waste

• Waste is not the problem; it is a symptom

• Waste points to problems within the system

(At both process and value stream levels)

• We need to find and address the cause of Waste

Work Sequence:Work Sequence: Key Future State QuestionsKey Future State Questions

Demand– Takt time ?

Material flow– Where can we use one-piece flow ?– Where can we use FIFO (first in- first out) ?– Where do we have to use supermarket-based pull ?

Information Flow– At what single point in production, can we do trigger production ?– How much work do we release and take away ?– How do we level the production mix ?

Supporting Improvement Initiatives– What other process analysis techniques could we utilize?e.g. - TPM (OEE,uptime), Poka-Yoke (mistake proofing), Changeover

Stocking Strategy Design ApproachStocking Strategy Design Approach

The key to designing the “right” stocking strategy is to understand…– Demand Variability– Customer lead time expectation– Internal process flexibility (part location/value

considerations)– Outside processing– BOM level changes– Distribution Centers – One to many/ many to one– Generic to unique differentiation points

and then design to these requirements/ constraints (examples follow…)

Demand VariabilityDemand Variability

Because customer demand has variability, we must buffer inventory to compensate.

This chart shows an “extreme” amount

of variability in demand, but for many companies this is not “out of

the ordinary”.

Purchasing

Supply Chain vs. Customer WindowSupply Chain vs. Customer Window

We typically buffer finished goods when the marketplace (customer) expects a shorter lead time than our process(es) can deliver.

Stocking Strategy comes into play in understanding where and what mix of “finished” goods to place in strategic buffers.

Standardized Operations Best PracticesStandardized Operations Best Practices

Only make a component or sub-assembly when it is needed at the next step (Just-in-Time)

Eliminate process disturbances - smooth flow

Capture and correct defects at the source (Jidoka) and find permanent corrections utilizing Root Cause Analysis (RCA) techniques

Standardize process and methods to reduce defects

Maximize Employee Involvement to help solve problems and improve processes
