Re: PPIG discuss: software estimating and partitioningpaper at http://www.cs.toronto.edu/~jaranda/pubs/MScThesis-JorgeAranda.pdf
presentation at http://www.cs.toronto.edu/~jaranda/pubs/Presentation-AnchoringAdjustment-Feb 05.pdf to the best of my knowledge the idea of the experiment was to include some minor expected duration information (an "anchor") into a document that was the basis for an estimation. in the experiment the estimators got heavily biased by this anchor. best regards, gerold -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von janice singer Gesendet: Montag, 22.

It seems like most people that are good at estimating do so by partitioning the problem into smaller pieces that can be handled more easily. Then, final estimates are accomplished by combining the pieces. This procedure is certainly what engineering approaches teach and I think other approaches as well. But I haven't been able to find much empirical data suggesting that software estimation done by partitioning is superior to that done more "wholistically". I assume that I am missing something huge and obvious since partitioning is such an important cognitive tool (and has been for such a long time). But, I haven't found empirical references yet Can anybody direct me to references on this topic.
