In general, we all share these same traits and the inescapable
problems as follows:

・ We jump from design to building too fast. Whether it's
writingcode or drawing circuits, the temptation to be doing rather
than thinking inevitably creates disaster.

・ We abdicate our responsibility to be part of the project's
manage- ment. When we blindly accept a feature set from marketing
we're inviting chaos: only engineering can provide a rational cost/
bene-fit tradeoff. Acceding to capricious schedules figuring that
heroicswill save the day is simply wrong. When we're not the boss,
then we simply must manage the boss: educate, cajole, and demonstrate
the correct ways to do things.

・ We ignore the advances made in the past 50 years of software
en- gineering. Most teams write code the way they did at age 15, when
better ways are well known and proven.

Whose "we"? For the last eight to ten years the only time I've been on a
project like you describe it's been forced on me by management -- given a
choice between not making house payments and acting like the above I'll do
it, but when I can (which has been surprisingly often) I do it right.

I suspect you'll find others on the group agreeing.

Sometimes It gets worse because of manage-ment guys when they
politicize the on-going project because of their busy-ness contacts or
any other reasons. I agree that engineer *should* demonstrate the
facts and document the options before saying _yes_ to big manage-ment
guy.
