  In diverse industrial and academic environments, the quality of the software
has been evaluated using different analytic studies. The contribution of the
present work is focused on the development of a methodology in order to improve
the evaluation and analysis of the reliability of web-based software
applications. The Personal Software Process (PSP) was introduced in our
methodology for improving the quality of the process and the product. The
Evaluation + Improvement (Ei) process is performed in our methodology to
evaluate and improve the quality of the software system. We tested our
methodology in a web-based software system and used statistical modeling theory
for the analysis and evaluation of the reliability. The behavior of the system
under ideal conditions was evaluated and compared against the operation of the
system executing under real conditions. The results obtained demonstrated the
effectiveness and applicability of our methodology.
