I believe that one cannot make an accurate time estimate without a technical specification. Once the technical specification has been drafted(that takes time) you can extract all the functions and allocate time to each one. Each function should be tested(xtreme programming) as u unit.
I know this sounds like the ideal world but I have burnt my fingers so many times with this. The less experienced you are the more necessary this becomes.
In the real world though, the PM comes along and casually asks how long it will take and expects you to thumb suck some estimation in 5 mins about a 2 month project! Most of the time the client doesn’t know what they want yet ect ect.
Just make very sure about what you say because TIME = MONEY in our world.

But
then there could be a situation where a PM "feels" that one is asking
for too much time..or perhaps another developer in the team could claim that
another developer is asking for too much time for what they
"perceive" to be an easy job. On 2/17/06, Carl Olivier <[EMAIL PROTECTED]> wrote: Heh.

Estimate to yourself (say 16 hours) - then double it (thus 32 hours) then double it again (64 hours) and quote that. Haha - seems ott I know - but with scope changes, bad specs, etc - you will find it usually goes there anyways...
And if not - you look good! Although if you always come in at half the estimate time this will also suck. :)
Don't use that all the time - but have in teh past -specifically for difficult clients ;)

On Behalf Of Jeff Mutonho Project managers will
always ask for estimates on the time a developer thinks he/she is gonna spend
coding something.I know experience plays a major role in this , but generally
speaking ,what techniques do you guys use?Any rules of thumb?Lies ,etc :) ?
