Fred
Brooks, Kenan Professor of
Computer Science at the
"How
Do We Know What to Design? How Linear Can the Design Process Be?"
25th
January 2008, 2-3pm Room 1.10,
Most engineers seem to have an implicit
rational model of the design process, that starts with requirements and
objectives, proceeds to a design concept, then gets detailed, delivered, and
maintained. Set forth in the 1960s-1970s by Herbert Simon, Pahl & Beitz,
and Winston Royce (as the Waterfall Model in software), this model has
dominated our thinking and even our formal processes.
We will examine what's right with this
model and what's wrong with it. I assert that it is not merely difficult, but
in fact impossible, to get the requirements for an original system design right
before one begins doing the design. We will look at alternatives that have been
proposed, ask why an unrealistic model has persisted so long, and ask where do
we go from here.
