Software Engineering Proverbs

A clever person solves a problem.
A wise person avoids it.
-- Einstein

André Bensoussan once explained to me
the difference between a programmer and
a designer:

"If you make a general statement, a
programmer says, 'Yes, but...'
while a designer says, 'Yes, and...'"

No matter what the problem is,
it's always a people problem.
-Jerry Weinberg

Wexelblat's Scheduling Algorithm:
Choose two:

Craziness is doing the same thing and
expecting a different result.

Tom DeMarco, rephrasing Einstein, who said

Insanity: doing the same thing over and
over again and expecting different results.

"There's no time to stop for gas, we're
already late"

We know about as much about software
quality problems as they knew about the
Black Plague in the 1600s. We've seen
the victims' agonies and helped burn the
corpses. We don't know what causes it;
we don't really know if there is only
one disease. We just suffer -- and keep
pouring our sewage into our water supply.
-- Tom Van Vleck

The Troops Know
* The schedule doesn't have enough
time for maintenance in it.
* A lot of bugs get past the tests.
* Most old code can't be maintained.

To go faster, slow down. Everybody who
knows about orbital mechanics
understands that.
-- Scott Cherf

Everybody Knows:
* Discipline is the best tool.
* Design first, then code.
* Don't patch bugs out, rewrite them
* Don't test bugs out, design them out.

Everybody Knows:
* If you don't understand it, you
can't program it.
* If you didn't measure it, you
didn't do it.

Everybody Knows:
*If something is worth doing once, it's
worth building a tool to do it.
*Your problem is another's solution;
Your solution will be his problem.

Everybody Knows:
* If you've found 3 bugs in a
program, best estimate is that there are
3 more.
* 60% of product cost comes after
initial shipment.

The significant problems we face cannot
be solved by the same level of thinking
that created them.
-- Albert Einstein

On the radio the other night, Jimmy

It is not enough to do your best: you
must know what to do, and THEN do your best.
-- W. Edwards Deming

A leader is best when people barely know
that he exists.
Less good when they obey and acclaim him.
Worse when they fear and despise him.
Fail to honor people, and they fail to
honor you.
But of a good leader, when his work is
done, his aim fulfilled,
they will say, "We did this ourselves."
-- Lao-Tzu

You must be the change
You wish to see in the world
-- Gandhi

Experiment escorts us last,
His pungent company
Will not allow an axiom
An opportunity.
