Turning stated requirements into the constraints that actually bound a design.
No content yetFunctional vs Non-Functional
Behaviour versus quality of behaviour, and why only the second constrains structure.
No content yetArchitectural Drivers
The small subset of requirements whose change would force the structure to change.
No content yetQuality Attributes
Availability, latency, throughput, security, cost — expressed as testable scenarios.

How much one component must know about, or change alongside, another.
No content yetCohesion
Whether the things inside a boundary belong together and change for the same reason.

Composing a system from parts that can be understood and replaced independently.
No content yetSeparation of Concerns
Organising so that a change to one concern touches one place.
No content yetAbstraction & Encapsulation
Hiding mechanism behind contract, and protecting invariants by owning state.
No content yetArchitecture Styles
System-level organising shapes, and how they differ from problem-level patterns.
No content yetEvolutionary Architecture
Designing for guided incremental change rather than for correctness on day one.
No content yetFitness Functions
Automated checks that an architectural characteristic still holds.
No content yetArchitecture Documentation
What to write down, at what altitude, and what nobody will ever read.
No content yetTrade-off Fundamentals
Why every architecture is a set of purchases, and how to state what you gave up.
No content yetTechnical Constraints
Existing estate, skills, licences and platforms as inputs rather than obstacles.
No content yetArchitecture Roles
Solution, enterprise, domain and platform architecture, and where each is accountable.
