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.

Remember to offer to your customer (or boss) that they can get it done (1) fast, (2) cheap, or (3) good. Pick any two.

There is something called COCOMO that was developed and used almost 30 years ago to estimate time although it may not be applicable exactly to your work. However, its approach of taking into account many various technical (e.g., estimated number of modules or lines of code) and human (e.g., number of developers on the team that are skilled and familiar with the technologies) factors is going in the right direction. But not matter what estimates are produced, management will browbeat the time downward and the development team almost always work like hell to meet the deadline.

Yes. I think its illegal to shoot female software developers, as they are an endangered species.

I start by estimating a number based on experience. I only use factors of ~2. e.g. 1h, 2h, 4h, 8h, 1d, 2d, 4d, 2w, 1m, etc. Anything more specific is just a guess. Then I quadruple it. 1/4 is to make up for the fact that I'm lying to myself about how long it will take. 1/4 is for when I come across bug X in component Y and waste a day or more on it. 1/4 of that is so I can properly document the project, code, and write a developer's manual. I am meticulous about keeping track of my time, and lately I have been within 10% of my estimate. :cool:

It doesn't matter how you estimate it, because whatever you think it will take you, it'll take longer... Or just come up with a guesstimate and multiply it by two.

I used to get stuck doing estimates, turns out I was fairly good at it, even though I hated every minute of it. They made me estimate the pieces and then brick them into a Microsoft Project file. I always gave them a tirade about how stupid that was, complaining all the while about what I called "Horizon Effect" (You see the mountain you want to climb in the distance, you bring pitons, ropes, and supplies, but after you get over the horizon you find that deep canyon and the fast running river running through it. Oops) But then I'd do it. Can't say how I did it. I'll guess that I looked at the complexity and could somehow estimate the volume of code which translates to how long it will take to write it. But that's experience talking about doing something similar to what I've done before. If it is totally new, all bets are off, that requires research and you don't know how deep that rabbit hole goes.

If you think it will take an hour estimate a work-day, if you can do it in a day, estimate 5 work days, a week -> 2 months. It's amazing how that works out to be pretty accurate. With the hour, you start coding, 10 minutes in, you go "what about..." You hunt down the guy who knows, get the answer. Start coding, someone asks you... By the end of the day snarl at anyone who dares approach you and finish the one hour project to be within estimate.

Take the number they give you and multiply it by PI (3.14), for going around in circles.

The first quarter is my initial estimate.
