Arc Skills / Verification and validation
Write a verification close-out report
Arc Skills brings the controlled baseline, current results, configuration, and anomaly decisions into one report draft. It returns a count-reconciled disposition and a clear recommendation for the authorized reviewer.
Use this skill
Use Arc Skills to draft a verification close-out report for the supplied baseline.
Inputs:
- Controlled in-scope requirement baseline, configuration, and report cutoff
- Current matrix and Run or report index with exact evidence locators
- Failures, incomplete work, anomalies, deviations, waivers, exit criteria, and sign-off records
Return scope, evidence index, reconciled disposition, open actions, exit assessment, and blank sign-off block.
Do not count an unsigned waiver as accepted or a failed Run as verifiedWhat you provide and what you get
| What you have | How it is used | What you get |
|---|---|---|
| Controlled baseline | Fixes ten-row denominator and revisions | Scope/configuration table |
| Evidence index | Links each obligation to exact current result | Disposition register |
| Exception records | Shows anomalies, waivers, and authority state | Open actions and sign-off block |
Eight demonstrated, one failed, one incomplete
Illustrative engineering example.
The illustrative cutoff is baseline B on article A-3. Runs E-1 through E-8 demonstrate R-1 through R-8; E-9 records a valve timing failure; R-10 has no Run. Waiver W-1 for R-9 is unsigned.
Baseline B: R-1…R-10, all in scope. Article A-3.
E-1…E-8: current Pass for R-1…R-8.
E-9: R-9 valve closure 2.3 s against ≤2 s.
R-10: Test T-10 planned, not run. W-1: proposed waiver for R-9, unsigned.| Disposition group | Evidence index | Report conclusion / open action |
|---|---|---|
| R-1–R-8: 8 demonstrated | E-1…E-8, article A-3, baseline B | Current passes; retain exact per-ID report locators in final index. |
| R-9: 1 failed | E-9: 2.3 s > 2 s | Open anomaly and owner disposition; W-1 unsigned, not accepted. |
| R-10: 1 incomplete | T-10 planned; no Run | Execute or formally disposition under plan. |
| Sign-off | Reviewer and authority fields blank | Recommendation: do not declare baseline verified at cutoff. |
The count reconciles: 8 + 1 + 1 = 10 in-scope requirements. The failed observation is not a “covered pass,” and an unsigned waiver has no approved effect on the technical result.
The report excerpt below maps all ten requirements to specific evidence or an unrun Test. It leaves source revision details and exit criteria as placeholders because they were not supplied; a closed campaign can still have open requirement close-out actions.
Close-out report excerpt
Verification close-out report — illustrative excerpt
Scope: Baseline B, R-1 through R-10, article A-3.
Cutoff: after E-9 and before T-10 execution; report date [not supplied].
Disposition: 8 demonstrated; 1 failed; 1 incomplete. Total: 10.
Evidence index (exact report revisions/sections: [not supplied]):
R-1 → E-1 Pass R-2 → E-2 Pass R-3 → E-3 Pass R-4 → E-4 Pass
R-5 → E-5 Pass R-6 → E-6 Pass R-7 → E-7 Pass R-8 → E-8 Pass
R-9 → E-9 Fail, 2.3 s against ≤2 s; W-1 proposed and unsigned
R-10 → T-10 planned; no Run
Plan exit criteria: [controlled plan and criteria not supplied].
Gate assessment: undetermined against the plan; R-9 disposition and R-10 execution open.
Recommendation: do not declare baseline B verified at this cutoff.
Technical reviewer: __________________ Date: __________
Approval authority: _________________ Decision: ______ Date: __________Reconcile before writing the conclusion
- Fix report cutoff, requirement baseline, article, and exclusion rules.
- Map each requirement to current evidence and the applicable acceptance result.
- Count demonstrated, failed, incomplete, and formally dispositioned exceptions exactly once.
- State unmet exit criteria and open owner actions; leave approval fields for authorized reviewers.
Questions about this task
Can W-1 make R-9 verified?
An unsigned proposal cannot. Even an approved deviation is a formal disposition, not a retroactive passing measurement.
Why include R-10 if its Test is planned?
Because the baseline includes R-10 and a planned Test has no executed result at the cutoff.
