1. We transacted most of our data exchanges through e-mail and fax, with some telephone and web mixed in.
2. Every data exchange was paper or PDF based. Structured data? I can hear the underwriter evilly laughing in the background. Yes, please, send me your structured data so we can print it out and transfer it into our underwriting forms manually.
3. Get me a quote and fax it... (On the hazard insurance policy).
Sure, that is interoperable... As 20th century medicine.
P.S. What the finance sector has learned is how to use interoperability to take THEIR costs out of the system, not MINE. We should remember that for healthcare too.
