Weeks in ReviewPhysically Efficient vs. Market-Responsive
Physically Efficient Process
Market-Responsive Process
Primary purpose Supply predictable demand efficiently at the lowest possible cost
Respond quickly to unpredictable demand to minimize stockouts, forced markdowns, and obsolete inventory
Manufacturing focus Maintain high average utilization rate
Deploy excess buffer capacity for flexibility
Inventory strategy Generate high turns & lower inventory cost
Deploy significant buffer stock of all stock items
Lead-time focus Shorten lead time at low cost
Invest in ways to reduce lead time
Approach to choosing suppliers
Select primarily for cost and quality
Select primarily for speed, flexibility, and quality
Product-design strategy Maximize performance at minimum product cost
Use modular design to postpone product differentiation

Decision Classifications
Strategic Planning: Decisions that typically involve major capital investments and have a long term effect
1. Determination of the number, location and size of new plants, distribution centers and warehouses
2. Acquisition of new production equipment and the design of working centers within each plant
3. Design of transportation facilities, communications equipment, data processing means, etc.

Performance Measures What you measure is what you get Performance measures strongly affect
the behavior of managers and employees
Tailor your performance measures to fit company’s mission and strategy
Over-reliance of a single measure might be detrimental to company’s long-term survivability

Critical Factors in SC Performance Metrics
Establish performance objectives with customers in mind
Consider using order windows as the basis for order fulfillment metrics
Reflect reliability issues in the metrics they choose
Implement metrics consistently throughout the supply chain
Aggregate results as they move up the chain

Critical Factors in SC Performance Metrics (cont’d)
Apply process control techniques to the business process
Avoid pitting players in the systems against one another
Collect only data you really intend to use
Communicate the actions and rational to everyone

What are the Causes…. Demand forecasting
Min-max inventory level Order-up-to level orders increase more than forecasts
Long cycle times Long lead times magnify this effect Impact on safety stock Product life cycle
Batch ordering Volume & transportation discount

What are the Causes….
Price fluctuation Promotional sales Forward buying
Inflated orders Orders placed increase during shortage
periods IBM Aptiva orders increased by 2-3 times
when retailers thought that IBM would be out of stock over Christmas

Ways to Cope with the Bullwhip Effect
Reducing uncertainty Centralizing demand information Bullwhip inherent in use of various forecasting
techniques Reducing variability
Use of EDLP strategy (Payless)

Ways to Cope with the Bullwhip Effect (cont’d)
Lead time reduction Order lead time (time to produce and ship) Information lead time (time to process
order) Efficient network distribution design
