Conclusions
Architectures and Integration are key for Capability,Flexibility and Affordability throughout the life cycle• Decomposed in flexible domains and optimized domains• Able to meet new operational requirements affordably• Able to benefit from upgraded technologies and technology shifts• Handles product, process and supply chain in a coordinated way
Model Based Systems Engineering allows to utilize thepotential• Early Knowledge and storage of knowledge throughout life cycle• Shared understanding of requirements and solutions• Needed for competive lead times and quality• Increased confidence and reduced testing
