Designing for the Customer:
Quality Function Deployment
Interfunctional teams from marketing,
design engineering, and manufacturing
Voice of the customer

9. Designing for the
Customer:
Value Analysis / Value
Engineering
Achieve equivalent or better performance at a
lower cost while maintaining all functional
requirements defined by the customer
– Does the item have any design features that
are not necessary?
– Can two or more parts be combined into
one?
– How can we cut down the weight?
– Are there nonstandard parts that can be
eliminated?

Design For Logistics
• Design for Logistics uses product design to
address logistics costs
• Key Concepts of Design for Logistics
• Economic packaging and transportation
• Concurrent / Parallel Processing
• Standardization

Economic Transportation and
Storage
• Design products so that they can be
efficiently packed and stored
• Design packaging so that products can be
consolidated at cross docking points
• Design products to efficiently utilize retail
space

Greatest improvements related to DFMA
arise from simplification of the product by
reducing the number of separate parts:
During the operation of the product, does
the part move relative to all other parts
already assembled?
Must the part be of a different material or be
isolated from other parts already
assembled?
Must the part be separate from all other
parts to allow the disassembly of the
product for adjustment or maintenance?
