What is software architecture?
Systems Thinking purpose, components, boundaries and interactions
Architecture is… “The fundamental organization of a system, embodied in

None
None
An architecture considers … key processing scenarios ... constraints under
which the solution was designs … quality of service requirements … mechanisms that make up the solutions … key assumptions and design decisions ... models to help explain parts of the system
It helps us… … manage complexity from different perspectives ...
remember why we did things … navigate what we’ve built … structure our thinking … communicate to others about what we’ve built
The Architect Foreman? Master Craftsman? Surgeon? Lead Engineer/Dev?
