Does Nexus replace any of these systems?

No. Each system keeps its own records. Nexus runs the process between them and records each decision.

Does the summary cover every file, application and open task?

No; it covers the records available in the approved scope and asks the manager to resolve gaps rather than implying a complete asset discovery.

Does a departure automatically disable the account?

Not in this use case; the identity change requires the designated approval and is executed by a separate workflow step.

Enterprise use case · Workday + Okta + OpenAI

Leaver summary for handover

Employment and identity records are reviewed separately, leaving uncertainty about what must be handed over or checked. Handover owners receive a source-linked summary of known responsibilities and recorded access before departure actions are approved.

The model step runs against the AI provider you choose, including Anthropic, Google Gemini or a model you host yourself. Anything outside a pre-built action runs through an API, protocol or database call, or as Rules + Code in Python, Bash, Go, Java, .NET, PHP, PowerShell or JavaScript/TypeScript, with the same approvals and audit.

Architecture

One governed run

Trigger: Workday eventIntegration: Workday + OktaAI step: model of your choiceHuman ApprovalSystem Action: OktaAudit

How it starts: An authorized HR owner confirms a departure or releases its handover preparation in Workday.

Step by step

How the process runs

01
Establish the departure scope
Read the permitted Workday employment details, manager and effective date for the approved handover purpose.
02
Gather recorded access
Read the relevant Okta user, group, role and event context available to the authorized workflow.
03
Summarize responsibilities
The selected model organizes the available records into handover topics, recorded access and unresolved questions, citing the source for each item.
04
Validate with the owner
The manager reviews the proposed handover list and adds responsibilities or open work that the connected records cannot establish.
05
Release approved identity work
A separate Okta step applies only the access changes approved for the specified identity and effective time.

Control

Human decision and exception path

Human decision

The named manager validates the handover scope, and the authorized identity owner approves each access change. The model cannot decide which account to disable, who inherits access or whether an unlisted application has been removed.

Exception path

Ambiguous worker-to-identity matches hold the file before any access action.
Missing responsibilities or application coverage are listed as unknown, not evidence that no work or access remains.
Changed departure dates or cancelled leaver events return the related handover and access plan for review.

Evidence

What gets audited

Approved departure event and effective date.
Permitted Workday and Okta references used by the model.
Summary, explicit coverage gaps and manager corrections.
Access approvals and the corresponding Okta responses.

Nexus runs on premises, in private or sovereign cloud, or air-gapped. Credentials stay in the vault, roles decide who can approve, and the execution record stays inside your deployment boundary.
