It's nothing to do with expert systems. Whoever wrote it decided to reuse an well-established existing term for their own purposes. The title ran a bell in my head, though. In the mid 1980s, to demonstrate Personal Consultant Plus, a commercial EMYCIN clone developed by Texas Instruments, to potential customers, I developed an expert system with it called CAFES - short for Choosing Architectures for Expert Systems. This was based on a technical report of the same name by Paul Kline and Steven Dolins.
