Decision Assurance.
The discipline that makes every consequential decision complete, consistent, governed, grounded, and on the record — and provable — without replacing human judgment.
The distinction quality learned a century ago.
Every organization already has decision control — the act of rendering the verdict: who approves, who signs off, who says yes or no. Almost none has decision assurance — the system that ensures the decision was made well, and can prove it.
The gate.
Reactive and decisive. A point-in-time judgment on a specific proposal — approve the sound, stop the flawed. It answers one question: "Is this a yes or a no?" The human, and the board, hold it.
The discipline.
Proactive and preventative. The system that puts the right criteria, evidence, and records in place so decisions are sound, consistent, and defensible. It answers a different question: "Are we deciding the right way — and can we prove it?"
Assurance is what makes control trustworthy. It ensures the decider sees everything relevant, applies the same rules every time, and leaves a defensible record — and then a human renders the verdict. Like Quality Assurance and Quality Control, the two are complementary. You need both.
Arclave is the assurance layer. It deliberately does not take control.
Most "decision AI" sells control — let the machine decide. Arclave sells assurance — make every human decision provably sound. That is the category, and the honesty, in one line.
Arclave doesn't make the decision. It makes the decision defensible.
Decision Assurance Levels.
Not every decision deserves the same rigor. Decision Assurance Levels (DAL) grade a decision A through E by what happens if it is wrong — and prescribe how much assurance, and how much automation, each level requires. The framework is the direct descendant of Design Assurance Levels in safety-critical aerospace engineering, where the standard DO-178C grades software by the severity of failure. We extend that logic; we do not claim its certification.
| Level | Decision profile | Required assurance | Autonomy cap |
|---|---|---|---|
| DAL A | Catastrophic, irreversible, enterprise-wide. A wrong call threatens the business, safety, or regulatory standing. | Full board, all domains, plus an independent second review; complete evidence, rationale, and dissent recorded. | Advisory only — a human always decides. |
| DAL B | Critical, hard to reverse, major. Significant cost or risk; expensive to unwind. | Full board review; evidence-cited findings; constitution enforced; human decides on the record. | Human decides; AI may recommend with conditions. |
| DAL C | Significant, moderately reversible. Real but bounded impact. | Standard board review; AI surfaces concerns and enforces inviolable rules; human sign-off. | Decide with human confirmation. |
| DAL D | Minor, reversible, local. Limited, easily corrected impact. | Light review; AI recommends; human spot-check or veto window. | Decide with a human veto window. |
| DAL E | Negligible, fully reversible, no material effect. Conformant to an established standard. | Automated assurance with complete logging. | Autonomous, with an audit trail. |
The higher the stakes, the more a human keeps control; the lower the stakes, the more you can safely automate. When in doubt, classify up — under-assuring a high-stakes decision is the costly error. The Decision Assurance Levels are intended to live as an open, vendor-neutral standard, stewarded by the Decision Assurance Council; Arclave is its reference implementation.
A lineage you can trust.
The word assurance carries a demanding pedigree. In every field, it means the same thing: justified confidence produced by a systematic process — distinct from the act of inspection.
Quality
Manufacturing and software. Quality Assurance built the system; Quality Control inspected the output.
Design
Safety-critical aerospace (DO-178C, ARP4754A). Justified confidence that a design meets its requirements, graded by severity of failure.
Information
Security. Justified confidence in the confidentiality, integrity, and availability of information.
Audit
Accounting and financial reporting. Justified confidence that the statements can be relied upon.
Decision Assurance extends that lineage to the one domain that never had it: the decision itself.
From archive to arclave.
To lock a decision so it holds — to make it provable. You archive a document. You arclave a decision.
Archive descends from the Greek arkhē — origin, rule, the house of records. Arclave carries that lineage forward with the Latin clavis, the key that locks it, as in conclave.
