Analiza przyczyn problemów jakości oprogramowania na podstawie ankiet osób uczestniczących w procesie wytwarzania systemów informatycznych

The level of failure of IT projects is high and has not changed over many years despite improvement in software development processes. One of the obvious reasons for this is shortening the delivery time of information systems in the projects and rapidly changing technology. Quality assurance in software development process is a key issue in ensuring the proper operation of an IT system. In order to know the causes of the problems, it is important to know viewpoints of members of the teams developing software. These views were obtained by carrying out the survey. At the beginning categories of reasons are identified using Ishikawa diagram, a tool for quality management. In the next step an analysis was performed using the Pareto principle. The analysis allowed the identification of the most important causes of errors in the software development process. A detailed analysis of the observed results and appropriate conclusions of this analysis will help improve the processes of software development and collaboration between project management and software development processes.
