This can be seen on several levels, e.g. on the application landscape level, the software level, the hardware level, etc. This paper presents a stepwise approach for consolidating IT landscapes on the technology, software and hardware level which considers the specifics of large IT organizations and is implemented in one of the largest IT service providers of Germany's public civil administration. It is based on metrics which use concepts from fuzzy logic. In particular, these metrics allow measuring the degree of standardization of parts of as well as of the overall IT landscape.enText/Conference Paper1617-5468
