Introduction to Sociotechnical Engineering
summary
Argues systems engineering applies to sociotechnical systems by writing functional and nonfunctional requirements (example: make technical decisions without a single-person approval), modeling roles as responsibilities for artifacts (roles are responsibilities for artifacts), and using a DSL that maps people, roles, and artifacts to expose dependencies. Reuses tactics like redundancy (assign lead role to two people) and test+removal (run an external audit while one architect is on vacation) to validate changes. Troubleshooting follows the rule bugs are relative to requirements and focuses on dissolving messes (merge coupled components to stop excessive meetings).
