Professional firms often depend on one or two people for decisions, client relationships, regulated responsibilities, banking, systems and institutional knowledge. That concentration becomes operational key-person risk when the practice cannot continue safely without instructions from that person.
The issue is not only death, incapacity or a long-term event. An unexpected hospital admission, communications blackout or other period where the principal cannot give instructions can expose the same dependencies immediately.
Common examples include deadlines visible only to one person, client decisions waiting for one principal, systems tied to personal credentials, payments requiring one approver, regulated work with no eligible fallback, and provider relationships that have never been tested without the principal.
Succession planning usually addresses a longer-term ownership or leadership transition. PCO tests the operating period before any long-term transition is resolved: who can act now, what they may do, what they can access, and what must escalate.
The Practice Protection Diagnostic examines 12 protection areas. If the client proceeds, the Practice Protection Implementation includes the Guided Governance Review and preparation and completion of the Practice Protection Plan, with the PPP then managed through NEXUS.
