| Summary: | Measures taken to prevent faults from slipping through to operation can secure
development of highly reliable software systems. One such measure is analyzing
the root causes of reoccurring faults and preventing them from ever appearing
again. PRORCA method was developed in order to provide a proactive,
lightweight and flexible way for fault prevention. To this end, PRORCA method
relies on expert knowledge of the development context and development practices
to identify individuals’ erratic behaviors that can contribute to faults slipping
through to operation. The development of the method was done according to
teachings of design science research. Three expert interviews with representatives
of a case company supported the development of PRORCA. The first interview
helped the problem identification and solution generation, while the other two
interviews were carried out with the purpose of demonstrating the use of the
PRORCA method in two different projects. Using the PRORCA proved to be easy
and insightful findings were drawn from conducting it with respect to individuals’
erratic behavior in each project. Proactive analysis of faults using the PRORCA
method supports development of highly reliable software systems in a simple,
flexible and resource-friendly manner.
