3. Outline Introduction Modularity and Product Platforms Managing Product Platforms Platform Management Strategies Modular Function Deployment HMMWV Conclusion

4. Introduction Product Modularity Development Increasing Complexity Increase Efficiency Expanding Technology Streamlining Need for Automation Changing Demands

5. Modularity and Product Platforms Product Modularity Product Platforms Advantages of Modularity Module Drivers Levels of Modularity

6. Advantages of Modularity Increased Flexibility Shorter Lead Time Lower Cost Improved Quality Better Service Ease of Upgrades

7. Module Drivers Technology Evolution Product Changes Common Units Styling Service & Maintenance Upgrades & Recycling

8. Levels of Modularity

9. Managing Product Platforms The Power Tower Market Applications Product Platforms Common Building Blocks

10. Common Building Blocks The Fuel for Product Platforms Customer Insights Product Technologies Manufacturing Technologies Organizational Capabilities

11. Product Platforms Subsystem Interfaces Platform Leverage Evolving Entities Manufacturing

12. Platform Strategies Niche-Specific Platforms Horizontal Leverage Vertical Scaling Beachhead Strategy

13. Niche-Specific Platforms Common in Industry Perfect Product for Each New Customer Complex Manufacturing Fragmented/Risk Losing Modularity Least Effective Application

14. Horizontal Leverage Subsystems Leverage from Niche to Niche Streams of Products to Related Customers Easier to Manufacture Less Time, Lower Cost, Better Performance Spread of Flaws in Key Subsystems

15. Vertical Scaling Scale to Particular Market Segments Top-Down or Bottom-Up Requires More Flexibility High-End Needs vs. Low-End Costs Weaknesses of Key Subsystems

16. Modular Function Deployment 1) Define Customer Requirements 2) Select Technical Solutions 3) Generate Module Concept 4) Evaluate Module Concept 5) Optimize Modules

17. Step 1: Define Customer Requirements The Army’s needs:Product Properties: transportationmodularization recovery mechanismsize durable partsweight easy maintenanceshape long lifematerial safepower firing platform protect soldiers (from weather and enemy)

18. Step 2: Select Technical Solutions Transport Soldiers Provide Protection (basic and supplementary armor / canvas) Provide Power (selected engine) Provide Durability (selected materials)

19. Step 3: Generate Module Concept The Product Platform M998 Utility Truck Derive the Modules: Winch Armor Protection Tow Launcher Platform M60/MK19 Platforms Shelter 4 Litter Ambulance 2 Litter Ambulance Maintenance Module

20. Step 4: Evaluate Module Concept HMMWV uses Base Unit Assembly

21. Step 5: Optimize / Implement Modules Test / develop the module specifications. Complete detailed design work for each module. Manufacture and assemble modules on the product platform. M998 Utility Truck

22. Step 5: Applied Modules

24. Conclusion Why do we create modular products? ComponentsProduct Platforms Product Families. The Army’s HMMWV.
