Arnie Lind, then a Senior Systems Engineer at IBM Canada in Regina, Saskatchewan created and named joint application design in 1974.
Arnie and Carl together named the methodology JAD, an acronym for joint application design, after Carl Corcoran rejected the acronym JAL, or joint application logistics, upon realizing that Arnie Lind's initials were JAL (John Arnold Lind).
Arnie Lind trained several people at IBM Canada to perform JADs, including Tony Crawford and Chuck Morris.
Arnie Lind retired from IBM in 1987, and continued to teach and perform JADs on a consulting basis, throughout Canada, the United States, and Asia.
[1] Originally, JAD was designed to bring system developers and users of varying backgrounds and opinions together in a productive as well as creative environment.
