Predictable Failure Prevention | Manual Transfer Between Components, v1.0

Defines conformance and assessment criteria for verifying that an organization manually initiates transfers between active and standby information system components at an organization-defined frequency if the mean time to failure exceeds an organization-defined time period.
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

1
Predictable Failure Prevention | Manual Transfer Between Components (PredictableFailurePreventionManualTransferBetweenComponents)
Does the organization manually initiate transfers between active and standby information system components [Assignment: organization-defined frequency] if the mean time to failure exceeds [Assignment: organization-defined time period]?
Artifact
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
Parameters
MTBF Thresholdrequired
NUMBER : Provide the threshold (percentage, 0-100) of the MTBF at which the organization manually initiates transfers between active and standby information system components.
Replacement Frequencyrequired
NUMBER : Provide the frequency (in hours) at which the organization manually initiates transfers between active and standby information system components when a component's MTBF threshold has been exceeded.
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.
