Knowledge-based Engineers
Software engineering owes much of its early existence to AI which pioneered the large-scale system construction
early AI systems were toy systems, written in Lisp (or whatever language) by the researchers themselves
By the 1970s, expert systems were being constructed
large scale endeavors, taking many man-years to produce
often built from scratch in Lisp, the programmers needed to have knowledge of programming, knowledge representations, and domain knowledge acquired from domain experts
A clear subdivision was made between the programmers and the domain experts who were brought it to impart their expertise
these programmers were given the title knowledge-based engineers (KBE)
they pioneered prototyping, programming tools, iterative lifecycle construction, and other concepts now found in SE
