#62I've been developing for 30 years. When asked for an estimate I spend time thinking about it and then when I come up with a number I multiply it by 3. Usually this works but sometimes I can be off. My typical process is to score stuff from "totally get it" to "don't have it all in my head". I then guess on hours and in the end multiply by this 3 factor. When my clients complain about the estimate I often say we "writ…
Take your original estimate, double it, and move to the next higher units. A one hour job ends up taking two days. Two weeks goes to four months. Scarily enough, I've worked with people whose multipliers are this large.

#63I tend to have a darker, more cynical view. Asking for an estimate is often a power play or "microaggression". It's more often about showing dominance than any legitimate business need to know this unknowable quantity. It plays a programmer's present self against her future self. Her future self wants an accurate or even pessimistic estimate to be made, so there are no unpleasant surprises to management and painful c…
But, yeah, often it's just bullying to drive a bad bargain. Most management HATES iterative development, because it's too honest.
One of my favorite Ed Yourdon quotes: "Vote with your feet" (from "Decline and Fall of the American Programmer, which scared the hell out of me, rightly so in some cases - and after working with off shore development, that scared the hell out of me)

#64Every project has 'gotchas'. And I don't mean just every coding project, I mean every project anywhere, ever. Part of the key of navigating those 'gotchas' is to immediately communicate it to your stakeholders when you run into one. Sit down and watch HGTV for a an hour or two, and you'll see that carpenters, plumbers, electricians, and HVAC contractors all run into problems - 'Whoops, this wall is load bearing, we'l…
I spent (I think) about two years walking by a sign in the south loop that said something like "coming in October of 2005, Target" and I thought, well, that's a pretty bold estimate for completing a building. Damn if that isn't exactly when they finished. Maybe they were changing the sign periodically and I failed to notice.

#65One of the best things you can do in your organization is create a culture that treats obstacle discovery as forward progress. There is nothing more disheartening for an engineer than banging her head against the wall trying to debug some race condition only to get flak from management about why it isn't fixed and why it's holding up some milestone. The root of this problem is management that doesn't understand the p…
Just to play devil's advocate, there is also the type of person who tends to get stuck down rabbit holes more than they should. There's a skill not just to solving problems but avoiding them in the first place. Usually this requires not just engineering talent but the ability to see the bigger picture, in terms of product and business goals. If someone is banging their head against the wall, it may be because they ar…

Its just that people are often-times so bad at communicating with each other. Anger rarely helps there, either..
