Advice

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

New products get more complex over time
Many of today’s product development teams are multi-disciplinary and incorporate suppliers

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.”

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.”

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.”

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?

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

Product StructureCommunication Tools are Lacking

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”

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

Product Structure Meaning
the framework for product data through a lifecycle

How Product Structure Can Help
Division of responsibility
Communication/change hub

Text manipulation:Word, WordPerfect

Spatial relations:CATIA

Mathematical calculation:Excel, Lotus 1-2-3

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

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

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

Product Structure and MRP/ERP
PROS
Some ERP/MRP systems include PDM functionality

Product Structure and MRP/ERP
PROS
Some ERP/MRP systems include PDM functionality
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

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

Advice
Focus on product structure FIRST during development
Pick the best tool for the job at EVERY stage
Product structure definition
Detailed design
Production planning
Field service and repair

Advice
Focus on product structure FIRST
Pick the best tool for the job at EVERY stage
Use the tools to communicate across disciplines

Advice
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

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

Advice
How Do You Start?
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

Advice
How Do You Start?
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?

Advice
How Do You Start?
Identify your needs
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?

Advice
How Do You Start?
Identify your needs
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
