Implementaiton Status

FedRAMP only accepts only one of five values for implementation-status: implemented, partial, planned, alternative, and not-applicable. A control may be marked "partial" and "planned" (using two separate implementation-status fields). All other choices are mutually exclusive.

If the implementation-status is partial, the gap must be explained in the remarks field.

If the implementation-status is planned, a brief description of the plan to address the gap, including major milestones must be explained in the remarks field. There must also be a prop (name="planned-completion-date" ns="http://fedramp.gov/ns/oscal") field containing the intended completion date. With XML, prop fields must appear before other sibling fields (such as set-parmeter, responsible-role, etc.), even though that sequence is counter-intuitive in this situation.

If the implementation-status is alternative, the alternative implementation must be summarized in the remarks field.

If the implementation-status is not-applicable, the N/A justification must be provided in the remarks field.

The FedRAMP implementation-status property at the control's implemented-requirement level is a summary of all statement and/or component level core OSCAL implementation-status designations. It must be set appropriately based on the least value of child statement or component level implementation-status designations. When a statement and/or component level implementation-status designation is not specified, the FedRAMP implementation-status value is assumed. Individual statements and/or components may override implementation-status locally.
