# NIST SP 800-161 Rev. 1: workflow for collecting and validating C-SCRM supplier evidence

A practical NIST SP 800-161 Rev. 1 Supplier Assessment Evidence Workflow with steps, owners, evidence fields, decisions, and source-linked review triggers.

*Workflow* *GLOBAL* *NIST SP 800-161 Rev. 1*

## NIST SP 800-161 Rev. 1 Supplier Assessment Evidence Workflow

Use the cited NIST sources to turn framework language into owners, evidence, review cadence, and decisions that a reader can act on.

Use this workflow to turn NIST SP 800-161 Rev. 1 supplier-assessment guidance into a repeatable process. It helps teams request evidence, review sources, make clear decisions, and track follow-up in a way that supports procurement, controls, and ongoing risk review.

## Request and review workflow

Use the table-like bullets below as the minimum workflow structure. Expand them only when the scope or risk requires more depth.

- 1 | Intake | Owner: requester and supplier risk owner | Evidence: scoped request, system or supplier name, business objective, source question.
- 2 | Source selection | Owner: risk or control lead | Evidence: external URL, short quote, applicability rationale, exclusions.
- 3 | Evidence collection | Owner: implementation owner | Evidence: policy, test result, contract clause, scan output, incident log, or assessment record.
- 4 | Decision | Owner: accountable executive or delegated risk owner | Evidence: approve, remediate, defer, accept risk, or escalate.
- 5 | Review | Owner: assurance lead | Evidence: review date, next trigger, changes, residual risk, and open actions.

## Put this NIST SP 800-161 Rev. 1 C-SCRM guidance into practice

Use the cited sources to turn the guidance into scoped decisions, owners, evidence requests, and review checkpoints.

- [Open Assessment Autopilot for NIST SP 800-161 Rev. 1 C-SCRM](/solutions/assessment.md): Create source-linked tasks, evidence requests, and review checkpoints for this NIST SP 800-161 Rev. 1 C-SCRM scope.
- [Review this NIST SP 800-161 Rev. 1 C-SCRM scope with Sorena](/contact.md): Check source coverage, ownership, evidence gaps, and next steps before publishing or operationalizing the work.

## Decision checkpoints

The workflow should force explicit decisions where teams usually leave ambiguity. Each decision should cite the source and explain what evidence is enough.

- Is the scope enterprise-wide, system-specific, supplier-specific, software-release-specific, or incident-specific?
- Does the source create a required action, a recommended practice, or an informative reference?
- What evidence demonstrates implementation and what evidence only demonstrates intent?
- Who can accept residual risk and what escalation path applies?

## Evidence fields

A reusable workflow is only useful if the evidence fields are consistent enough for audits, customer assurance, and independent review.

- Source URL and quote supporting the claim.
- Claim text in reader language.
- Owner, reviewer, due date, and review trigger.
- Evidence artifact, storage location, version, and collection method.
- Gap, corrective action, exception, or risk acceptance status.
