01 / The context
Engineering complex software systems requires more than code.
Mission-critical software must remain deterministic, maintainable and verifiable while products, requirements and teams continue to evolve.
Product Complexity
Software architecture must scale across products and missions without creating duplicated implementations.
Verification
Requirements, implementation and test evidence must remain connected as systems grow.
Hardware Integration
Flight software must integrate reliably across processors, buses, sensors, actuators and programmable logic.
02 / Capabilities

03 / Method
Engineering principles
Deterministic
Timing, resource usage and failure behavior should be understood and controlled.
Reusable
Product-specific functionality should build on stable, reusable platform capabilities.
Verifiable
Architecture should make requirements, behavior and evidence easier to understand and test.
Maintainable
Software should remain understandable and adaptable throughout the lifecycle of a product family.
