DECISION ASSURANCE & READINESS INTELLIGENCE

Sentinel 20

Evidence-governed decision assurance for complex projects, systems and programmes.

Structure evidence, expose critical gaps, challenge assumptions, test decision robustness, explore scenarios, manage corrective actions and maintain an auditable progression record from one integrated workspace.

Decision-use boundary

Sentinel 20 is commercial decision-assurance software. Its outputs structure readiness, evidence, uncertainty, contradictions, critical conditions, scenarios and bounded progression. Sentinel outputs do not by themselves constitute certification, regulatory approval, professional sign-off, engineering authority, clinical authority, legal advice, financial advice or a probability of success.

Methodology assurance

Commercial product status is separate from methodology validation status. External scientific validation, certification, accreditation or independent benchmarking are only claimed where corresponding documented evidence exists.

Decision Assurance Workspace

Readiness, evidence and progression intelligence.

Review current readiness, evidence sufficiency, critical controls, decision robustness and progression from one integrated workspace.

Evidence Constraint

Declared readiness is not automatically accepted. Linked evidence limits the level that can be defensibly supported.

Current evidence-readiness ceilings are operational settings subject to future calibration.

Non-Compensation

Material contradictory evidence or unresolved critical conditions cannot be erased by high average scores elsewhere.

Step 1 · Define

Project & Decision Boundary

Define the project, operating context, consequence tier and one bounded decision question.

Methodology 1.1

Reviewer Governance

Independent-review status requires recorded competence, independence and conflict-of-interest information.

Information handling

Sentinel does not automatically save assessment data to localStorage or sessionStorage. Export the Decision Record when deliberate retention is required.

Step 2 · Evidence

Evidence Intelligence

Register the evidence supporting, contradicting or qualifying the claims used in this assessment.

0 records
ID Title Type Source Owner Date Version Declared Q Direction Directness Independence Method Applicability Limitations Uncertainty Defeater Severity
Evidence control

Principle-level evidence support cannot exceed the admissible support of the linked evidence set. Contradictory evidence remains visible and may block critical progression.

Step 4 · Control

Critical Controls

Critical conditions use non-compensatory logic. High overall readiness cannot cancel unresolved material evidence, authority or boundary failures.

Principle Criticality Supported R Supported Q Defeater Control State Reason

Step 5 · Stress-Test

Decision Robustness

Test whether the current progression position remains stable when the assessment is exposed to declared synthetic stresses.

This displays Sentinel decision logic. It is not a physical causal model.

Run a scenario to see how an intervention propagates through evidence, readiness, controls and progression.

Step 7 · Act

Action & Closure Management

Convert gaps into accountable actions. Closing an action does not automatically increase readiness; closure evidence must support reassessment.

Step 8 · Reassess

Assessment History

Maintain append-only baseline and reassessment snapshots in the exported Decision Record.

No baseline snapshot has been created.

Step 9 · Report
