Productivity vs. quality

Phil Haack linked to an interesting paper which intended to provide evidence that Test Driven Development increases the overall quality and productivity of developers on a given project.

I’m not going to debate the merits of TDD right now, did enough of that on Twitter last night ;) , but I did notice something interesting that I hope the group conducting the test follows up.

It’s in a PDF so I can’t quite link to the appropriate charts, but they are regression charts on page 10 and 11. One compares quality to # of tests written and the other compares productivity to # of tests written. (I’m summarizing). The interesting part to me was that there were some of the participants in the TL (test last) group that scored higher than some of the TF(Test First) group members. In fact, if I’m interpreting that chart correctly, the highest quality code was written by members of the TL group.

The second chart appeared to show that the overall productivity for ALL group members was low, with the exception of a couple of members who fell way outside of the C.I.

I also liked that it appeared that the regression lines were hand-drawn on after the fact. ;)
