Currently, efficient, flexible and cheap information systems are an economic necessity. This fact not only applies to information systems of large enterprises, but to an increasing degree also to those of small and medium-sized enterprises.

Small and medium-sized enterprises (SME) define the European economics in a special way. According to EU-definition they average 99.8% among European countries. Nevertheless, small and medium-sized enterprises do not exist.

Depending on the size, the field of activity, the key markets and the range of products and services, the demands of SME on their information technologies are diverse. The spectrum ranges from micro-sized enterprises that rarely use information technology and scarcely have expertise in their operation to medium-sized automotive-suppliers that are forced by their principal customers to apply certain standards. Depending on the size and the organizational form there are considerable differences among decision-making structures and the instruction of decision-makers.

The project Strategic Systems Landscape Engineering for SME is concerned with the strategic planning, the configuration and the operation of system landscapes in small and medium-sized enterprises in consideration of open source software. The applicability and the benefit of approved tools for planning and decision-making as well as the benefit of open source software for the planning, the configuration and the operation of system landscapes in small and medium-sized enterprises therefore are in the center of this consideration.

The integration of corresponding methods and information sources for an utilizable planning methodology for small and medium-sized enterprises as well as their prototypical implementation in an integrated tool for planning and controlling is the goal of this work.
