In Plain Language

Specialist roles provide deep domain expertise in critical areas that cross-cut ordinary software development. Organized into three distinct groups — Compliance & Security (8 roles), Operations & Reliability (3 roles), and UX & Usability Design (4 roles) — these 15 specialists safeguard regulatory compliance, platform resilience, and human-factors safety.

Cross-Cutting Domain Specialists (15 Roles)

Specialist roles provide deep technical authority in high-stakes disciplines such as cybersecurity, medical device risk management, and clinical usability. Specialists have independent authority to halt release progression if safety, privacy, or reliability thresholds are not satisfied. Acronyms used here include Root Cause Analysis (RCA), Root Cause Verification (RCV), Service Level Objectives (SLOs), and Protected Health Information (PHI).
