System area

Software Architecture

Decisions, interfaces, constraints, and viewpoints made explicit enough to inspect and maintain.

Scope

Where it helps

Use this area when system boundaries, dependencies, and tradeoffs need a durable shared model.

Inquiry

Questions LucyAI asks

  • Whose concerns shape the architecture?
  • Which decisions and constraints must remain visible?
  • Where do interfaces concentrate change or risk?

Outputs

Evidence

Source basis

Move with intent

Choose a next step

Start with the pressure you need to resolve, or prepare a local brief that keeps the problem, constraints, and evidence together.
