What happens when your systems are working, but a critical provider you depend on suddenly is not?
The 2024 Change Healthcare cyberattack showed how quickly that can become an operational problem.
The incident disrupted services used throughout the U.S. healthcare system, including pharmacy transactions, medical claims, payments, and other administrative workflows. HHS described the disruption as affecting healthcare and billing systems nationwide.
For many organizations, the affected technology was not theirs.
The dependency was.
That is the lesson for CFOs, COOs, Controllers, Fractional CFOs, M&A firms, VC teams, and investment banks:
Identify critical providers: Know which vendors are required for billing, payments, customer service, operations, and other essential workflows.
Test the outage scenario: Ask what the business can actually continue doing if that provider is unavailable for one day, several days, or longer.
Plan the alternative: Determine whether another process, provider, or manual workaround can realistically support the business while service is disrupted.
A company can have functioning internal systems and still lose the ability to complete critical work because someone else is down.
That makes vendor dependency more than a procurement issue.
It is a continuity issue.
Which outside provider would create the biggest operational problem for your business if it disappeared tomorrow?
