Before you touch the document
- Confirm the SSP is convertible. A convertible SSP has one addressable implementation statement per requirement. If yours is narrative prose organized by chapter, fix that first — under Rev. 2 — because a crosswalk needs units to walk.
- Freeze a Rev. 2 baseline copy. Version and archive the current SSP as the of-record document for active Rev. 2 contracts. Conversion happens on a branch, never in place.
- Inventory which contracts need which view. The conversion's output requirement comes from your contract mix, not from ambition.
The five conversion passes
- Pass 1 — structure mapping. Rebuild the skeleton on the 17 Rev. 3 families. Note the moves that surprise people: the SSP requirement itself relocates into the new Planning family, and Security Assessment becomes Security Assessment & Monitoring.
- Pass 2 — statement conversion. Walk the crosswalk requirement by requirement. Carried requirements keep their statements with updated citations; consolidated requirements get merged statements that preserve each parent's substance; new requirements get honest gap placeholders, not aspirational text.
- Pass 3 — disposition records. Every requirement gets a recorded disposition: satisfied as-is, satisfied with modification, gap (with POA&M entry), or not applicable with rationale. This table is the transition's audit trail.
- Pass 4 — ODP embedding. Each implementation statement that touches a parameter cites the ODP register value inline. An SSP that contradicts the register fails the cheapest possible test.
- Pass 5 — evidence re-pointing. Statements reference evidence by Rev. 3 assessment-objective index (see the evidence guide), so the document and the artifact library stay one system.
Maintaining both views
Until your last Rev. 2 contract closes out, you need both documents truthful simultaneously. The workable pattern: the Rev. 3 SSP becomes primary, with the frozen Rev. 2 SSP maintained as a derived view — changes flow through the crosswalk so an update lands in both. What doesn't work is two documents edited independently; they diverge within a quarter. Full operating model in dual-baseline operations.
Converted, not rewritten
SSP conversion is Station 03 of our Rev. 3 transition.
