Shows how dealerships can separate evidence capture, review, customer approval, administration, vendor support, and audit oversight.

Dealerships adopting automated vehicle inspection quickly move from asking how the system scans to asking who can view, change, approve, export, or delete the results. Those decisions affect customer conversations, service recommendations, integration behavior, and the credibility of the inspection record. A role model built around job titles alone is rarely precise enough. This article maps the major data actions to advisor, technician, manager, IT, and vendor responsibilities and shows how to test the separation before go-live.

Direct Answer: Separate Capture, Judgment, Approval, and Administration

No single routine user should be able to create an inspection event, change its findings, approve the customer-facing record, alter system rules, grant access, and remove the audit evidence. Divide those powers and require a second role for high-impact actions.

Four boundaries matter most:

• Evidence capture is separate from customer-facing approval.

• Report review is separate from system and access administration.

• Configuration changes are separate from operational use.

• Vendor support is authorized for a defined purpose rather than assumed as permanent authority.

The Elscope Vision Passenger Vehicle 4-in-1 Solution can provide body, underbody, tread, and sidewall evidence and supports API-based integration. The dealership must design identity management, approvals, retention, monitoring, and vendor-access rules for its own environment.

This follows a general control principle reflected in NIST SP 800-53 AC-5, Separation of Duties: organizations identify duties that require separation and define system access authorizations accordingly. The dealership should adapt that principle to its operational and legal context.

Define Actions Before Assigning Roles

Start with data actions, not people. The same person may perform multiple job functions at a small dealership, but the system should still distinguish the permissions.

The core actions are:

• initiate or retry a scan;

• view source images and measurements;

• annotate or review a finding;

• approve a customer-facing report;

• change thresholds, templates, or workflow rules;

• create users and assign permissions;

• manage integration credentials and data exports;

• approve retention exceptions or deletion;

• install updates or change model and rule versions;

• review access, configuration, export, and override logs.

Each action should have an owner, an approver where risk warrants it, and an audit record. Avoid shared accounts because they erase accountability.

Use a RACI and Access Matrix

The following matrix is a starting point, not a claim about the product's built-in roles. Dealerships must map it to the controls available in their deployed system and connected applications.

Keep Evidence Capture Separate From Review

The person operating the lane may notice a problem, but the source record should not depend on that person's memory. Preserve the scan identity, source images, measurements, module status, and original system output before review.

The Dragate Arch Scanner uses a 17-camera configuration for exterior capture, while the underbody scanner provides 4K imagery and recognizes published underbody finding categories. Those evidence streams should remain linked to the inspection event when a reviewer annotates or disputes a finding.

If the same employee captures and reviews the event because staffing is limited, require manager approval for release and preserve the original output alongside the review. The control is separation of authority, not necessarily a different person at every minor step.

Define the Customer-Report Approval Gate

An internal AI finding is not automatically a customer recommendation. The approval workflow should confirm that the finding belongs to the correct vehicle, the source evidence is accessible, module completeness is understood, and any human correction is documented.

The approving manager should not need technical administrative privileges. Approval authority and configuration authority answer different questions: whether this report is ready for use, and how the system behaves for every future report.

For high-impact corrections, require a reason code and second-person review. Keep the original finding, the revised disposition, who changed it, and when.

Restrict Configuration and Credential Changes

Thresholds, report templates, integration mappings, and rule versions can affect many future inspections. Treat changes as controlled deployments rather than routine edits.

Require:

• a change request describing purpose and affected workflow;

• approval by the business owner and technical owner;

• test evidence in a non-production or controlled environment;

• a planned activation time and rollback method;

• confirmation that the audit log captured the change;

• post-change validation on representative records.

API credentials deserve separate treatment. Use individual or application identities where supported, document each integration's purpose, restrict access to what is needed, and rotate or revoke credentials through an approved process.

Scope Vendor Access as a Dealership Decision

Vendor support may be needed for commissioning, updates, diagnosis, or integration. Do not assume either permanent access or zero access. Define the actual support model.

For each vendor session, record the ticket or purpose, approved systems and data, start and end conditions, dealership approver, actions performed, and evidence retained. Prefer supervised or time-bound access where the deployed tools support it. Remove or disable temporary access after the task and review the related logs.

The product's API and local-data features do not automatically enforce the dealership's vendor-access policy. Configuration and operating procedures must implement the boundary.

Protect Export, Retention, and Deletion

Bulk export can expose more data than viewing one report, while deletion can destroy evidence. Both actions need stronger controls than ordinary report access.

Define which roles may request an export, approve it, execute it, and verify delivery. Log the purpose, scope, destination, and result. For deletion or retention exceptions, require a documented basis, conflict check for holds or disputes, approval, execution record, and verification.

Do not state that local storage alone provides compliance. The dealership owns retention, backup, recovery, access review, and legal-hold procedures.

Implement the Role Model in Nine Steps

1. Inventory actions and systems. Include the inspection platform, DMS, identity provider, storage, reporting, and integrations.

2. Map current users to actions. Find shared accounts, excess privileges, and conflicting duties.

3. Define role permissions. Separate capture, review, approval, configuration, provisioning, export, deletion, and log review.

4. Add approval gates. Require a second role for customer release, high-impact correction, export, deletion, and configuration change.

5. Document vendor support. Define request, approval, scope, supervision, evidence, and termination.

6. Test negative cases. Confirm each role is blocked from actions it should not perform.

7. Test audit evidence. Verify that access, change, override, export, and deletion events identify the actor and time.

8. Train users by role. Explain both what they can do and where the escalation path begins.

9. Review after change. Reassess access after staffing, integration, workflow, or system changes and after suspicious events.

FAQ

Can one person hold more than one role?

Yes, especially at a small site, but high-impact actions should still require independent approval or compensating review.

Should an advisor be able to delete an inspection record?

Routine advisor access should not include deletion. The dealership should define a controlled request, approval, execution, and verification process.

Does the vendor automatically manage dealership users?

That depends on the deployed architecture and agreement. The dealership must confirm who provisions users and retain authority over its access policy.

How should vendor troubleshooting access work?

Authorize the specific purpose and scope, record the session, and end temporary access after the task using controls available in the deployment.

Who should review audit logs?

Assign a role independent of routine operation and set triggers based on risk, staffing changes, privileged actions, and detected anomalies.

Keep the Approval Path Clear

Segregation of duties protects the credibility of the inspection record by separating evidence creation, judgment, approval, administration, and oversight. The right design reflects the dealership's size and risk while preserving accountability for high-impact actions.
