Stable section ID: S05-CON-014-SECTION-45 · 16 content blocks
Every System05 implementation shall define its System Boundaries, Asset Boundaries, and Responsibility Boundaries.
A System Boundary identifies what is included within a System05 system, subsystem, building, service, or conformance claim.
An Asset Boundary identifies where one independently managed Engineering Asset ends and another begins.
A Responsibility Boundary identifies who has authority and accountability for design, manufacture, installation, verification, operation, maintenance, modification, and retirement.
Each controlled boundary shall identify:
- Included and excluded functions.
- Physical and digital limits.
- Interfaces crossing the boundary.
- Transferred loads, energy, fluids, data, or authority.
- Ownership and custody.
- Inspection and maintenance responsibility.
- Failure containment and emergency authority.
- Required evidence at transfer points.
Shared responsibility shall not remain undefined for safety-, structural-, fire-, utility-, configuration-, or compatibility-critical activities.
Contractual delegation, automation, subcontracting, or third-party service shall not silently transfer constitutional accountability. Responsibility shall remain assigned to an identifiable authorized person or organization.
Where two systems interact, each side shall remain responsible for satisfying its declared obligations at the common Interface.
