MO-006e — Infrastructure Environment Retirement

Go to MO-006 — Infrastructure Lifecycle Management

Statement

Crucible SHALL transition an Infrastructure Environment to Retirement when the applicable Retirement conditions are satisfied.

Derived From

This requirement derives from:

The Original Requirement states:

The system SHALL support infrastructure lifecycle management from initial deployment through retirement.[C1]

MO-006e preserves the terminal lifecycle intent expressed by through retirement in the Original Requirement by requiring Crucible to transition an Infrastructure Environment to Retirement after satisfaction of the applicable Retirement conditions.

The separate requirements derived from MO-006 address:

Assessment

The Original Requirement identifies Retirement as the end of infrastructure lifecycle management but does not define the required Retirement transition.

Without an explicit Retirement requirement, an evaluator cannot reliably determine:

Which Infrastructure Environment is subject to RetirementWhich lifecycle state precedes RetirementWhich conditions permit the Retirement transitionWhich approvals or authorizations applyWhether unresolved operational, security, compliance, or preservation obligations block RetirementWhether Retirement completed successfullyWhether the Infrastructure Environment entered the Retirement stateThe Evidence required to demonstrate RetirementThe phrase through retirement embeds a separate terminal lifecycle obligation within the broader lifecycle-management requirement.

MO-006e:

Identifies Crucible as the responsible actorIdentifies the Infrastructure Environment as the subject of the transitionIdentifies Retirement as the target lifecycle stateRequires satisfaction of the applicable Retirement conditions before the transitionSeparates Retirement from lifecycle assignment, lifecycle initiation, current-state determination, and general lifecycle-transition execution

Rationale

Retirement represents the terminal lifecycle state of an Infrastructure Environment when the assigned Operational Lifecycle defines Retirement as its terminal state.

Retirement conditions can include:

Authorization by the responsible authorityCompletion of required operational activitiesResolution or disposition of outstanding failures and exceptionsPreservation of required configuration recordsPreservation of required deployment recordsPreservation of required security recordsPreservation of required compliance recordsPreservation of required EvidencePreservation of required ProvenancePreservation of required TraceabilityCompletion of required data dispositionCompletion of required Artifact dispositionCompletion of required resource dispositionRevocation of applicable credentials and accessTermination of applicable servicesCompletion of required archival activitiesThe assigned Operational Lifecycle defines the applicable Retirement conditions. Not every condition listed above necessarily applies to every Infrastructure Environment.

Infrastructure Environment Retirement supports:

Controlled termination of infrastructure usePrevention of premature RetirementCompletion of required preservation and disposition activitiesRevocation of obsolete accessRelease or disposition of infrastructure resourcesPreservation of lifecycle historyConfirmation of the terminal lifecycle stateGeneration of auditable EvidenceSatisfaction of the Retirement conditions permits Crucible to execute the Retirement transition. Satisfaction of those conditions does not by itself establish successful completion of Retirement.

A failed or incomplete Retirement transition does not establish that the Infrastructure Environment entered the Retirement state. MO-006c governs determination of the current lifecycle state after the transition attempt.

This requirement does not assign or initiate the Operational Lifecycle. MO-006a and MO-006b establish those requirements.

This requirement does not determine the current lifecycle state. MO-006c establishes current lifecycle state determination.

This requirement is the specific Retirement transition derived from the broader lifecycle-transition behavior established by MO-006d.

Notes for Editors

This requirement page should retain the stable requirement identifier MO-006e.

This page is a leaf requirement page and omits a trailing :start from its namespace.

Changes to the Statement should preserve the transition of an Infrastructure Environment to Retirement after satisfaction of the applicable Retirement conditions.

The Retirement definition should identify:

The Operational Lifecycle identifierThe Operational Lifecycle revisionThe Retirement transition identifierThe lifecycle state preceding RetirementThe Retirement target stateThe applicable Retirement conditionsThe responsible approval or authorization authorityThe Retirement completion criteriaThe Retirement failure criteriaThe required data dispositionThe required Artifact dispositionThe required resource dispositionThe required credential revocationThe required service terminationThe required archival activitiesThe associated ProvenanceThe associated TraceabilityThe supporting EvidenceMaterial changes should receive review and should update the related verification criteria, requirements realization, related architecture sections, and source records.
