Evolutionary Architecture - The art of making decisions
summary
Decision-making determines whether a system stays evolvable or becomes a rewrite: use architecture decision records with context, alternatives, pros/cons, and measurable KPIs so a bad choice is detectable; document C4 diagrams for zoomable intent and handoffs; prototype with disposable proofs (the upside‑down hanging model) and casted references, never ship PoCs as production; prefer simplicity, delegate noncore work to vendors, and design for the easy reversibility principle to minimize irreversible coupling.
