The real problem

At 4:57 PM on a Friday, a routine laboratory order failed.

The patient's sample was already in transit. The external reference laboratory rejected the request — it could not uniquely identify the patient. The insurance operator rejected authorization for a different reason. Neither system spoke the same language, neither exposed compatible error messages, and the only integration layer in the middle simply forwarded requests.

A laboratory technician spent the next 25 minutes navigating portals, copying identifiers, and manually reconciling data between systems.
