Abstract
In order to improve software maintenance processes, we first need to be
able to characterize and assess them. These tasks must be performed in
depth and with objectivity since the problems are complex. One approach is
to set up a measurement-based software process improvement program
specifically aimed at maintenance. However, establishing a measurement
program requires that one understands the problems to be addressed by the
measurement program and is able to characterize the maintenance
environment and processes in order to collect suitable and cost-effective
data. Also, enacting such a program and getting usable data sets takes
time. A short term substitute is therefore needed.
We propose in this paper a characterization process aimed specifically at
maintenance and based on a general qualitative analysis methodology. This
process is rigorously defined in order to be repeatable and usable by
people who are not acquainted with such analysis procedures. A basic
feature of our approach is that actual implemented software changes are
analyzed in order to understand the flaws in the maintenance process.
Guidelines are provided and a case study is shown that demonstrates the
usefulness of the approach.
