Overview#
Automotive research and development is a complex, capital-intensive process spanning multiple years. Understanding the development lifecycle is crucial for anyone working in or with the automotive industry.
Development Dimensions#
Three Critical Factors#
- Key Objectives: What the vehicle must achieve
- Timeline: Development schedule and milestones
- Cash Flow: Investment scale and timing
Cost Management Approaches#
Value Engineering#
Systematic approach to identifying cost reduction opportunities while maintaining function:
$$ \text{Value} = \frac{\text{Function}}{\text{Cost}} $$Key Activities:
- Function analysis
- Creative alternatives generation
- Evaluation and selection
- Implementation
Target Costing#
Ensuring long-term profitability through cost targets:
$$ \text{Target Cost} = \text{Target Price} - \text{Target Profit} $$Process:
- Market research determines acceptable price
- Profit margin requirements defined
- Allowable cost calculated
- Design-to-cost approach applied
