Predictable Failure Prevention - Provides Substitute Components, v1.0

Defines conformance and assessment criteria for verifying that an organization provides substitute information system components and a means to exchange active and standby components at organization-defined mean time to failure (MTTF) substitution criteria.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Assessment Step

Predictable Failure Prevention - Provides Substitute Components (PredictableFailurePrevention-ProvidesSubstituteComponents)
Does the organization provide substitute information system components and a means to exchange active and standby components at [Assignment: organization-defined mean time to failure (MTTF) substitution criteria]?
Artifact
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.
