Or, as the sign at many printers says,

"Good. Fast. Cheap. Pick two."

The candidates try that all the time.

As well they should--it's the PM triple restraint for a reason. If the question doesn't state that resources are fixed, I think it's the correct first answer (full disclosure--I got dinged on an interview for not knowing the constraints like the back of my hand, so it's forefront of my brain).

However, I think the only useful answer to that question lies in corporate culture, and also varies from project to project. I've done either, and times either has been the best thing to do, or neither. My preferences have nothing to do with what guarantees the success of any given project.

I'm sure an interviewer doesn't like that, but after fifteen years of managing projects, you aren't getting anything more definitive than that out of me.

Isn't that what makes it a good interview question, though?

Right -- the best answer depends on everything, including the level of the person you are hiring, their role, corporate culture, what the task is, etc. So if you're interviewing for a PM job, you'd better understand the nuances. But if you're interviewing for an entry-level grants management job, you'd better understand a deadline.

Isn't that what makes it a good interview question, though?

Not if I don't know corporate culture, no. Unless you want me to toss it back and say "It's not about me--it may not even be about you. It's about the business owner and the specific project priorities."

As an interviewer, I'd just be looking for people who had a definite answer either way, and marking them down whichever side they picked.

In my job, we set the deadline so quality is more important. In my previous job deadlines were probably more important but the real answer is "superhumanly turn in perfect work by deadline." But anyway, as an interviewee I wouldn't necessarily know which is more important. It's a question that seem slightly unfair to me, given how much it depends on knowledge of the culture.

Not Paul Bettany issue, though.

I'd take it. As long as he was part of the long-term deal.

Breaking in to say that today is National Bittersweet Chocolate Day.

Yeah--in my current job, I have a deadline for my initial report. I get dinged if I'm always turning it in late or if it's always crappy, but it's getting reviewed and edited. So if it's pretty ok I can count on the review cycle to shape it up, but I'd I really need time I can let them know we have less editing time. OTOH, the final report deadline, if it's not in by deadline we don't get paid. So they'd rather have something incomplete than nothing.
