I thought I would just start jotting down some ideas around this paper that I read today. The Paper is "An In-Vivo Study of the Cognitive Levels Employed by Programmers During Software Maintenance" by Tara Kelly and Jim Buckley. It was in the 2009 ICPC conference proceedings.
In this paper they start by assuming that Bloom’s Taxonomy of mental processing is used by programmers during maintenance tasks.
I was interested in how they were doing the research. They had 6 programmers speak all of their thoughts during a programming assignment into a voice recorder. They followed this by having the researchers analyze the utterances of the developers. They then categorized the utterances into the different levels of the taxonomy. However they admit that it was very subjective how they were making the categorizations.
They did have a few statistics that I would be interested in looking at the prior sources. One of these stats that I’m interested in reading from the first source, is that 90% of the total system’s cost is in maintenance. They quote this from the article “Leveraging legacy system dollars for E-Business” by L. Erlikh from the IT Pro publication of May/June 2000.
