Criticality & SECE Governance

Criticality and SECE are managed as two independent engineering axes. H / I / M / L / Z governs maintenance treatment; SECE adds mandatory assurance requirements and is never overridden by low production criticality.

SECE Assurance Layer

SECE is a barrier-assurance requirement independent from H/I/M/L/Z. The current source provides SECE markers and plan registration evidence.

Rule: Z can be screened as an RTF candidate only after legal, integrity, SECE, hidden-function and consequential-damage gates are cleared.

How Criticality and SECE Drive Maintenance Development

1 · Asset Criticality

Confirm H/I/M/L/Z as the governing equipment criticality.

2 · SECE Check

Evaluate barrier / assurance obligations independently.

3 · Strategy Treatment

Apply the relevant criticality treatment and mandatory assurance.

4 · SAP Evidence

Build controlled task, plan and execution evidence.
