The rule that the organization of the software and the organization
of the software team will be congruent; commonly stated as If you
have four groups working on a compiler, you'll get a 4-pass
compiler
. The original statement was more general,
Organizations which design systems are constrained to produce
designs which are copies of the communication structures of these
organizations.
This first appeared in the April 1968 issue of
Datamation. Compare
SNAFU principle.
The law was named after Melvin Conway, an early proto-hacker who
wrote an assembler for the Burroughs 220 called SAVE. (The name
‘SAVE’ didn't stand for anything; it was just that you lost
fewer card decks and listings because they all had SAVE written on them.)
There is also Tom Cheatham's amendment of Conway's Law: If a group
of N persons implements a COBOL compiler, there will be N-1 passes.
Someone in the group has to be the manager.
