Sentinel Defence Safety & Assurance Case

SentinelSAFETYMAN INTERNATIONAL

Defence · Safety & Assurance Case

A clear safety argument across changing operating contexts.

Build an explicit argument. Connect the controls and original evidence. Record the people, limitations and decisions behind each reviewed issue.

Available for controlled evaluation. Specialist acceptance and hosting suitability must be established before operational use.

A traceable argument

Context → claims → evidence → independent review

Unclassified support equipment only. No classified, export-controlled or operationally sensitive material is included.

Original sector framework · human decisions

This edition supports original unclassified case preparation. It does not confer MOD approval, accreditation or authority to release equipment.

Built around your review questions

Defence context, made explicit.

Northbank Support – maintenance support equipment

A fictional unclassified maintenance support system is reviewed for a changed workplace context. The exercise concerns equipment handling, competence and change control, not weapon design or operational tactics.

Explore the review scenarios

1. Establish the working baseline

Define boundaries, assign a case owner and record the relevant requirements and their current editions. The example begins in Draft; no claim is automatically supported.

2. A gap challenges the argument

A modification is absent from the assessed configuration baseline. Assessed configuration no longer matches Record the challenge against the relevant claim. Retain the source evidence and determine who must review it.

3. A supporting record changes

Update a linked assessment or shared control, then refresh the case. The dependency version mismatch prompts review. A subsequent draft may acknowledge the new version; a previously issued snapshot remains unchanged.

4. Review and controlled issue

Resolve completeness gaps, substantiate claims and submit to the assigned reviewer. Every contributor to that revision is excluded from approving it. Separate regulatory, clinical or operational decisions remain outside this workflow.

Connected to the Sentinel Suite

Use the work you already do.

Learn and challenge

Incident, Investigate and Investigate Pro provide findings that can challenge assumptions. Reference the applicable finding and assessment revision.

Control and verify

Use Bowtie and Assure records, register shared barriers and retain performance evidence. A changed barrier prompts reassessment of dependent cases.

Manage continuing assurance

Change, Compliance and Audit support controlled review. Authorised copies of Observe and Competence evidence can be attached; their original permissions remain separate.

Know what the edition does.

Is this certification or regulatory approval?

No. It manages arguments, evidence, version history and accountable review. It does not decide whether the technical argument is sufficient or whether operations may proceed.

What can I retain and export?

Original PDFs, Word documents, Apple Pages files and supported images can be uploaded to a case. Export Google Docs to Word or PDF first. Download original files separately, export JSON and generate printable case reports.

What information is suitable for this launch?

Use fictional or appropriately authorised evaluation information. This deployment has not been assessed for classified defence material, nuclear-sensitive information, patient-identifiable clinical records or sensitive cyber secrets. Sector labels do not establish hosting accreditation.

Can the edition be allocated separately?

Yes. An administrator allocates each edition to a company. An active company annual licence and manager role are required to write. Existing authorised managers retain read/export access after expiry.

Does the desktop include this edition?

No. These new case editions are cloud add-ons. Desktop case synchronisation and sector-specific desktop validation are separate work.
