  Software development enterprises are under consistent pressure to improve
their management techniques and development processes. These are comprised of
several disciplines like requirements acquisition, design, coding, testing,
etc. that must be continuously improved and individually tailored to suit
specific software development project. This paper presents an evaluation
approach that enables the enterprises to increase development process net
benefits by improving disciplines' quality and increasing developers'
satisfaction. Our approach builds on Kano's model of quality. Based on an
empirical study of top 1000 enterprises from Slovenia we find that application
of software development methodologies in individual development disciplines
significantly relates to net benefits of IT projects. The results show that
different types of Kano quality are present in individual disciplines.
Enterprises should be cautious when altering must-be quality disciplines like
testing or deployment as they can significantly disrupt the established
routines, cause great dissatisfaction between developers and significantly
reduce benefits. On the other hand, changing the attractive quality disciplines
like requirements acquisition can notably increase developers' satisfaction and
benefits but is less likely to disrupt the established routines.
