The Last 5%

An old saying is it takes 5% of the time to complete 95% of a software project, and 95% of the time to finish that last 5%. True or false?

I’ve yet to work on a software project that was ever actually deemed ‘finished*’!

* Unless by ‘finished’ you mean ‘scrapped’…

Absolutely true!

I’ve never worked on a product that could be considered 100% complete and finished – There is always some slight tweak.

Basically it’s quick to get a proof of concept (or the 80% solution) going… but it takes a bucket load of time to cater for all the boundary conditions.

Wow. I actually quit as soon as the easy 95% is done and start a new %95 with a different employer and leave that detail stuff up to the poor sons-o-guns who believe in long-term employment.
