How do you estimate time fir writing code? If your manager ask you to give him a time for something to be done?

Experience.

It's not an exact science - it's guess work based on "how long this took me last time" plus a bit of "how accurate and complete is the spec?" with a soupcon of "what else do I have to do at the same time?" and some extra "padding time to make me look good". Occasionally there is also "How much am I being paid for this?" and "how much do I like this guy and want to do this?"

Complex.

So about 8.73 working days, probably.

Does that include tea and fag breaks?

Don't drink tea, don't smoke. So no.

Coffee breaks are extra, natch.

They prefer to be called gay and openly admitting to attacking them isn't good form.

In the UK a fag is a cigarette.

In the US a fag can also mean a cigarette. I was kidding about it's other meaning. Drag changes based on context too, it could relate to a cigarette or a way of dressing. Strange language, English. Gay means happiness.

Think of a number, add 2 and multiply by 3.

So based on Griff numbers:

(8.73 + 2) * 3 = 32.19

OMG | :OMG:

No, no, no! You are supposed to think of a number, not me!

Isn't it a slandered timing for writing code

i thougt 50.
using your formula i calculated 156...
now i´m thinking about the measure...
is it minutes, hours or what? Sniff | :^)

finally, i chose "days"...
quite relaxing for me, but not for the Manager... $Shucks | :-\$

All of them: 156 hours, 156 minutes, and 156 "what?" (although I'm sure your manager will helpfully provide most of those Wink | ;)

)

GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

My technique isn't too far from that:

Take a wild-ass guess at the time it would take if I were certain the requirements were firm and that there would be no interruptions while I'm working on it;
Double the number;
Promote the unit to the next higher value.

So if I figure I could knock it out in an hour under "ideal" conditions, I estimate "2 days." If my wild-ass guess is two weeks, I submit an estimate of "4 months." And so forth.

The remarkable thing about this approach, which I first suggested as a gag of sorts, is that it's proved to be pretty reliable in practice -- seldom more than about 10% from the actual time required, and never more than 25% off. Somehow it accounts flexibly for requirements changes, imposition of unanticipated constraints, distractions and interruptions, and acts of God. There's a lesson in there, somewhere...
