The quality of software has not improved despite new programming schemes,
innovative research on software testing, and well-thought approaches to process
improvement. The study reported in this article indicates that the normal
process-improvement thinking alone does not enable sufficient improvements in
the quality of testing and the quality of the final software. One very important
part of producing high quality software is the availability of necessary skills.
We analyze three industrial cases in which required testing skills are lacking
and the lack of skills is caused mostly by the lack of proper education and
training. Therefore an important factor in the software quality problem is
insufficient education. In addition to the analysis, we outline some possible
solutions to the problem.
