Re: Lines of Code - negative defects
A couple of years later the developers were asked to break the work into 'tasks' of 1-2 weeks duration, and they started to track these.
They found it more accurate when they had to size the work if someone else had to do it (if I do it, it will take a week. If Fred does it it will take 2 weeks - we'll say 2 weeks.)
For each task they had to identify dependencies and so there was some real project management, and reordering of work.
