Usually software development is an evolutionary
process. Most process models for software development do not
sufficiently consider this aspect, even so Rational's Unified
Process (RUP). To counteract this defect an evolutionary,
object oriented development process is proposed (EOS). This
process model is originally independent of methods. One aim of
the dissertation was to define methods for the EOS sub
processes project management, software development, quality
management, configuration management and use and evaluation. A
further aim was to work out a tool, which supports all the
defined methods in a systematic way. Therefore a prototype for
a process management system was developed.
