Efficient architectures have to be optimized on vehicle and
component level
Focus of a
standard-
ized parts
strategy
Vehicle design
(macroarchitecture)
• Define packaging zones
• Determine organization of components
• Define levels of freedom for
microarchitecture
Ensure compatibility of
macroarchitecture in
family concepts
(e.g., electronics
architecture)
Component design
(microarchitecture)
• Design components
• Systematically optimize number of variants

Automotive software development adds a new layer of complexity
compared to hardware
Source: Brooks: The Mythical Man-Month, McKinsey
• High number of tacit requirements
• Heavy software and hardware interaction for embedded systems
• Project complexity growing steeply with product size
• Intangible product, hard visualization and performance tracking
• General mismatch between scope and available resources -
projects always seem to be "nearly" complete

• High degree of change in underlying complex technologies
• No widely accepted platform standards
• Immature tool landscape
• Fast-moving (and in many cases immature) markets
• Customer value hard to assess
• Lack of experience translating customer requirements into

• Inherent tendency to over-engineering
• Seemingly low cost of changes

efficiency
Operational improvement can be achieved in a three step approach
• Restructuring of development organization for
specific needs of SW projects is necessary
• Building of specific skills in SW development and
SW project management is needed
• Modular, feature specific product design is key to
reduce complexity and enable concurrent engineering
• Platforming and maximal degree of reuse is neces-
sary to overcome complexity challenge and ensure
software quality
• Complex software projects are only feasible with
standardized, repeatable processes
• Development effort depends heavily on process
maturity - efficiency potentials of up to 90% are
possible
