D004: Case-study framework: Problem → Decision → Outcome

Context: Featured work must prove product thinking, not just output. Saif has the projects; metrics will be filled in by him.

Decision: Every featured project (ueue, Prism, salutebutton, Zazz) uses Problem → Decision (calls + trade-offs) → Outcome (metrics) + role, stack, links. Structure now, metrics later (chosen by Saif).

Why: Reframes "I built X" into "I made good calls that paid off." Metrics make it undeniable. Directly serves D001 - Site as Proof Principle.

Applied across the two-track layout in D012 - Work Section Structure; full list in Projects.

Trade-offs: depends on Saif supplying real numbers; placeholders clearly marked until then. Open item tracked in Open Questions (#9 metrics).
