How the Volumes Work Together¶
The ETIS framework follows the complete lifecycle of intelligent systems.
The two volumes divide this lifecycle into two major domains of responsibility.
Volume I: Foundations, Engineering Practices, and System Construction¶
Volume I focuses on engineering systems before sustained operation begins.
Core questions answered include:
- What are we building?
- Why are we building it?
- How should it be engineered?
- How should AI participation be controlled?
- How do we prepare systems for release?
Topics include:
- Foundations
- Requirements engineering
- Architecture
- Planning and estimation
- AI governance controls
- Repository-centered engineering
- Implementation
- Reviews
- Release preparation
Volume II: Operations, Governance, and Engineering Stewardship¶
Volume II focuses on sustaining systems after release.
Core questions answered include:
- How do we operate systems?
- How do we sustain trust?
- How do we govern AI over time?
- How do we manage incidents?
- How do we reduce complexity?
- How do we steward systems over years rather than releases?
Topics include:
- Postmortems
- Stabilization
- Observability
- Operational readiness
- Security governance
- AI delegation
- Reliability engineering
- Incident response
- Release governance
- Stewardship
The transition between the two volumes reflects one of the central ETIS principles:
A release is not the finish line. A release is an organizational commitment to ongoing stewardship.
