The important of architecture

Transcript

1. The importance of architecture
2. Today…
5. The shed is about this big:
6. Software is hard!
8. Essential Complexity Complexity, Conformity, Changeability, and Invisibility
9. Accidental Complexity Programming, hardware limitations, deployment, debugging
10. Simplifying the accidents
11. Simplifying the essence
12. Why is architecture important?
13. Anti-patterns emerge
14. Quality neglected not fit-for-purpose
15. Quality is neglected entropy is not managed
16. What is software architecture?
17. Systems Thinking purpose, components, boundaries and interactions
18. Architecture is… “The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution.”
19. Architecture embodies the critical design decisions of a system
20. Why should we apply rigour?
23. 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
24. 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
25. The Architect Foreman? Master Craftsman? Surgeon? Lead Engineer/Dev?
28. Summary…
29. Great designers create great systems
