10 GRIPEN Breaking the cost curve

11 Spiral development VS. MID-LIFE UPGRADES Capability WS 22 Ed 21 Ed 17 Ed 18 Ed 19 Ed 20 Ed 14 Ed 15 Ed 16 CAPABILITY GAP MID-LIFE UPGRADE Costly Constrained Complex and Delayed Time

12 Reduce total cost of ownership for customer Easily adapt to new operational requirements Respond to customers expectations on performance and functionality increase Substantially decrease development cycles Reduce cost to integrate systems and functions Reduce effort to upgrade equipment New Avionic System Structure Drivers More efficient distributed development - facilitate for partner and customer to participate in development Affordability Scalability Portability Reuse Supportability Openness Growth potential Re-configurability Testability

13 New Avionic System Structure Strategies Utilize technology leap: Efficient architecture Optimized methods and processes Model Based Systems Engineering tools with auto coder Challenges -> new engineering values Radical change in working All disciplines are effected Competence (general and specific domain) Process/ Methods Architecture Competence Tools Gripen Demo indicates >> 50% increased development efficiency Affordability Scalability Portability Reuse Supportability Openness Growth potential Re-configurability Testability

16 System characteristics: Flexibility vs. context stability Context Stability dynamic rigid Need for product segmentation or restructuring of solution (lack of flexibility) Modular functionality Innovative environment Flexible process Flexible supply chain adaptible System Flexibility Integrated and optimized functionality Stable process Stable supply chain Need to be stabilized through process and/ or supply chain (overcapacity in flexibility) stable

17 Gripen Avionics Step Change Context stability - Fast exec - dedicated h/w - optimized - Integ validation - modular System flexibility Accelerated change Increased integration Upgrade key success contributors -Leap in tech s and tools -Level of modelling& simulation -Selective change partitioning -Strong initial architecture -decomposition -interfaces - Fast exec - dedicated h/w - optimized - Integ validation - modular -H/W Optimized framework - Modelling FW - Autocoding - ARINC ARINC661 - Open HW stds Gripen NG design Flexible implementation -Functional models -Modular supply chain -COTS -Modular validation -H/W

18 Gripen Avionics Step Change -build up Gripen E Demonstrator requirements solutions

19 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 the potential 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
