It was a completely custom system built by another internal team at the company I was at. Once word got out, other people copied the system and tailored it for their needs. So it was definitely not a general purpose reusable system. I’ve talked to other people working at other large companies in the 90’s and they had similar experiences. I think either multiple people at different places recognized the need and value of systems like these before they were widely written about, or word was getting around in some circles. Not sure which.
