Build a second-tenant onboarding plan from a first deployment

The second tenant reveals whether a delivery is a product or a one-off. Anything established through undocumented manual edits, copied credentials or hard-coded identifiers will reappear as risk during onboarding.

Build the decision artifact

Extract tenant creation into a reviewed workflow: namespace, identity, data and index partitions, tool credentials, quota, cache partition, policy configuration, deletion route and observability access. Provide dry-run and rollback. Test with two synthetic tenants before touching a real environment.

The enterprise delivery lab makes this reasoning executable with synthetic data:

from enterprise_cases import second_tenant_case

result = second_tenant_case()
assert result["repeatable_controls"] == 6
assert result["tenant_specific_code"] is False
assert result["production_tenant_created"] is False
assert result["checklist"]["cache_partition"] is True

The lab records six repeatable controls and explicitly rejects tenant-specific code. It creates no production tenant. That boundary matters because a checklist can demonstrate design completeness without pretending provisioning or security review occurred.

Test the failure path

Automation can reproduce a weak first design faster. Test cross-tenant denial, default quotas, missing configuration and offboarding. Require every exception to name an owner and expiry; otherwise temporary tenant customization becomes permanent platform debt.

Save evidence that another reviewer can inspect:

• versioned onboarding schema and workflow
• two-tenant isolation test
• dry-run, rollback and offboarding evidence
• exception register with expiry

This exercise aligns with the enterprise delivery, secure integration, operations and leadership work in the FDE for Professionals course. The course link describes the pathway; this local draft and its synthetic verifier do not claim that a client deployment, security approval or production result occurred.

Practice task

Replay your first-tenant steps as if no original engineer were available. Every undocumented action becomes either automation, an explicit decision or a blocked prerequisite.
