Neon B-I-W Case Study
Chrysler Neon
- Program requirements
- Fun to drive
- Reliable
- Good value
- Fuel efficient
- B-I-W requirements
- Good structural characteristics to help achieve the "fun to
drive" objective
- A dimensional control plan to achieve "reliability"
- A body optimized for cost to achieve "good value"
- A body optimized for weight to achieve "fuel efficiency"
- Specific B-I-W objectives
- Structural integrity
- Design integrity
- Dimensional control
- Cost
- Weight
Product teams formedDoor systems
Sealing systems
- Bumper systems
Exterior trim
etc.
Process teams formedDimensional control
Materials
Stamping
Manufacturing
Assembly
Finance
etc.
- Timeline
- First year - each team "owned" its part
- Two years prior to launch - Process teams were aligned with product teams
(as "process" was consuming too much resources during product design)
- Primary objective of the body process teams
- Final "dimensional integrity" prior to prototype
- A complete CMM of B-I-W
Challenges
- Insuring component-level design intent
- Insuring assembly fixture & gages were to design intent
- Insuring coordination of component design changes and assembly fixture
changes
- Additional functional teams were formed
- Noise, Vibration, and Harshness (NVH)
- Operation of doors
- Hoods and decks
- Fit and finish of body panels
- Water sealing and wind noise
- CAE studies
All B-I-W program designs were done in CATIA
