Why Product Structure Matters
1. Why Product Structure Matters 2009-05-08 Jonathan Scott Principal Consultant, Razorleaf
2. Agenda Product Development Trends From the Field Product Structure Defined Where Product Structure Fits and Why The Right Tool for the Job Product Structure in Practice Advice
3. Product Development Trends Good product development practice includes: Requirements definition Design Validation Production
4. Product Development Trends Good product development practice includes: Requirements definition Design Validation Production Reduced time-to-market is a universal goal
5. Product Development Trends Good product development practice includes: Requirements definition Design Validation Production Reduced time-to-market is a universal goal New products get more complex over time
6. Product Development Trends Good product development practice includes: Requirements definition Design Validation Production Reduced time-to-market is a universal goal New products get more complex over time Many of today’s product development teams are multi-disciplinary and incorporate suppliers
7. From the Field Large Team Challenges “The left hand never could seem to figure out what the right hand was doing, and having 5 hands didn’t help. By the time we realized we missed something, it was too late to go back and design it right.”
8. From the Field Time Challenges “There was never any time to communicate – we were under such a tight schedule that we just had to throw it over the wall as soon as we had part of the design done. Our shop guys are good and I knew they would find a way to assemble it.”
9. From the Field Product Challenges “If the power guys and the controls guys could have shown me what they meant to do here, I never would have put the cooling where I did.”
10. From the Field Digging Into the Problems Where is product structure documented throughout design? Can everyone look at the product structure? How would two people discuss a product structure idea? How should product structure changes be communicated?
11. From the Field Conclusion Where is product structure documented throughout design? Can everyone look at the product structure? How would two people discuss a product structure idea? How should product structure changes be communicated? Bottom Line: Communication Tools are Lacking
13. Product Structure Defined Product Structure:a collection of items and item relationships sold or otherwise managed as a unit item = manufacturable entity item relationship examples include “belongs to”, “composed of”, and “is equivalent to”
14. Product Structure Defined Product Structure:a collection of items and item relationships sold or otherwise managed as a unit Product Structuring:process of breaking-down an end-item unit into logical substructures
20. The Right Tool for the Job Text manipulation:Word, WordPerfect
21. The Right Tool for the Job Text manipulation: Word, WordPerfect Spatial relations:CATIA
22. The Right Tool for the Job Text manipulation: Word, WordPerfect Spatial relations: CATIA Mathematical calculation:Excel, Lotus 1-2-3
23. The Right Tool for the Job Text manipulation: Word, WordPerfect Spatial relations: CATIA Mathematical calculation: Excel, Lotus 1-2-3 Logical structure manipulation:……
24. The Right Tool for the Job Product Structure and 3D CAD PROS Detailed product structure can be driven by 3D CAD Most designers are familiar with 3D CAD tools Most products require some mechanical (3D) design
25. The Right Tool for the Job Product Structure and 3D CAD PROS Detailed product structure can be driven by 3D CAD Most designers are familiar with 3D CAD tools Most products require some mechanical (3D) design CONS High-level product structure is concept or function-driven, not geometry-driven Product structure must be exposed to everyone as it evolves Changing product structure may need to drive 3D CAD also Structure comparisons are difficult Baselines can’t be kept
26. The Right Tool for the Job Product Structure and PDM PROS Object-Oriented DB + GUI = structure manipulation tools PDM tools allow product structure Creation Revision (Baselining) Comparison Derivation Multi-CAD PDM centralizes product structure 2D CAD -> PDM 3D CAD -> PDM ECAD -> PDM
27. The Right Tool for the Job Product Structure and PDM PROS Object-Oriented DB + GUI = structure manipulation tools PDM tools allow product structure Creation Revision (Baselining) Comparison Derivation Multi-CAD PDM centralizes product structure 2D CAD -> PDM 3D CAD -> PDM ECAD -> PDM CONS System nature of PDM prevents off-line work Not all PDM systems treat product structure independent of CAD structure
28. The Right Tool for the Job Product Structure and MRP/ERP PROS Some ERP/MRP systems include PDM functionality Object-Oriented DB + GUI = structure manipulation tools
29. The Right Tool for the Job Product Structure and MRP/ERP PROS Some ERP/MRP systems include PDM functionality Object-Oriented DB + GUI = structure manipulation tools CONS Lacks baseline management Disconnected from design tools Needs layer to abstract design processes from production processes Often cumbersome to use, hampers creative design processes
46. Advice So What Should You Do? Focus on product structure FIRST during development Maybe second – right behind requirements definition Well before doing detailed design work
47. Advice So What Should You Do? Focus on product structure FIRST during development Pick the best tool for the job at EVERY stage Requirements definition Product structure definition Detailed design Production planning Field service and repair
48. Advice So What Should You Do? Focus on product structure FIRST Pick the best tool for the job at EVERY stage Use the tools to communicate across disciplines
49. Advice So What Should You Do? Focus on product structure FIRST Pick the best tool for the job Use the tools to communicate across disciplines Integrate your best-in-class tools RM CAE PDM ERP/MRP
50. Advice How Do You Start? Get management support The project is going to need people The project is going to need money The project is going to take time
51. Advice How Do You Start? Get management support Identify your needs Assess what’s already in place (CAD, ERP, etc.) Identify what’s missing Product Structure Management Requirements Management Digital Mockup Etc. Develop a case for why those are needsnot wants
52. Advice How Do You Start? Get management support Identify your needs Identify your resources Who else in the organization has problems like these? Who has budget for the areas you’re trying to improve? Which of your existing partners have expertise? Is there upcoming work that might “fund” the project?
53. Advice How Do You Start? Get management support Identify your needs Identify your resources Set priorities What is most important to your organization? What is most important to your sponsor? What is the quickest “win” that can give momentum?
54. Advice How Do You Start? Get management support Identify your needs Identify your resources Set priorities Proceed in a phased approach Taking on too much always kills a project People like to be on the winning team – be the winner Funding a successful project is easier than starting new
