Claim	C007

Claim: Knowledge engineering in the 1980s initially had "little formal process."

BLUF: Confirmed. Historical accounts of expert systems development in the 1980s document that early knowledge engineering had little or no formal methodology. Researchers "just sat down with domain experts and started programming." Formal methodologies like KADS emerged later as the field matured.

Probability: Very likely (80-95%) | Confidence: High
