2. DFMA – Design for manufacturing and
assembly
• Industrial product design aspects
– Aesthetics – shape, colour, texture
– Material – manufacturability , tolerance
– Assembly convenience – practical, technical, economical
• Design for manufacture (DFM) and Design for assembly (DFA)
• Concurrent engineering
• Lean manufacturing
• DFMA software from Boothroyd Dewhurst, Inc. , US
– DFM Concurrent Costing software
– DFA Product Simplification software

3. DFMA considerations
• How does the part move during operation
with respect to other parts ?
• Material used
• Need to disassemble the product -
maintenance / adjustment

4. Design over the wall ? NO !

5. Example…….
Traditional USE OF DFMA

6. DFMA results into
operational savings –

9. Designing Service Products
• Services are heterogeneous – variance
• Direct customer interaction – time to serve
• Service product design considerations
– Experience fit e.g. McDonald offering toys with
Happy Meals
– Operational fit e.g. home delivery from grocery
store
– Financial impact

10. Experience fit or operational fit ?
