IntroductionProduct Modularity Development
• Increasing Complexity• Increase Efficiency• Expanding Technology• Streamlining• Need for Automation• Changing Demands
Modularity and Product Platforms
• Product Modularity• Product Platforms• Advantages of Modularity• Module Drivers• Levels of Modularity
Advantages of Modularity
• Increased Flexibility• Shorter Lead Time• Lower Cost• Improved Quality• Better Service• Ease of Upgrades
Module Drivers
• Technology Evolution• Product Changes• Common Units• Styling• Service & Maintenance• Upgrades & Recycling
Levels of Modularity
Managing Product PlatformsThe Power Tower
• Market Applications• Product Platforms• Common Building Blocks
Common Building BlocksThe Fuel for Product Platforms
• Customer Insights• Product Technologies• Manufacturing Technologies• Organizational Capabilities
Product Platforms
• Subsystem Interfaces• Platform Leverage• Evolving Entities• Manufacturing
Platform Strategies
• Niche-Specific Platforms• Horizontal Leverage• Vertical Scaling• Beachhead Strategy
Niche-Specific Platforms
• Common in Industry• Perfect Product for Each New Customer• Complex Manufacturing• Fragmented/Risk Losing Modularity• Least Effective Application
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
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
Modular Function Deployment
1) Define Customer Requirements
2) Select Technical Solutions
3) Generate Module Concept
4) Evaluate Module Concept
5) Optimize Modules
Step 1: Define CustomerRequirements
The Army’s needs: Product Properties:transportation modularizationrecovery mechanism sizedurable parts weighteasy maintenance shapelong life materialsafe powerfiring platformprotect soldiers (from weather and enemy)
Step 2: Select TechnicalSolutions
Transport Soldiers
Provide Protection(basic and supplementaryarmor / canvas)
Provide Power(selected engine)
Provide Durability(selected materials)
Step 3: Generate ModuleConcept

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.
