Companies are faced with rapidly changing requirements, historically grown, heterogeneous IT application landscapes and short technological innovation cycles. For business information systems to operate in this field of tension, flexible and agile concepts are needed - both in the development of individual applications as well as in the evolution of IT application landscapes.
The increasing decentralization of energy management due to the growing number of decentralized, renewable generators requires changes to the established communications and power distribution structures. These are usually not coverable by existing IT systems - integration in a plug-and-play seldom possible. An increasing number of new standards and norms are under development to achieve the interoperability of field devices and control systems. OFFIS is actively participating in national and international standardization processes, such as the IEC or the German VDE / DKE. The CISE (Center for IT Standards in the Energy Sector) is the OFFIS competence center for automation and network control technology and provides training in standards, support during the implementation of projects and guidance for technology choices by manufacturers, energy suppliers and advisors.
A future energy supply system based increasingly on IT - the so-called "Smart Grid" – is one exciting application field of architecture development and interoperability in which the group AEI is active. With the increasing need for the decentralized management of energy flows and the growing number of decentralized, renewable generators, changes to the current communication and power distribution structure become necessary. These are usually not coverable by existing IT systems so that the further development of the individual architectures of IT systems and their interaction is required. The group AEI applies its broad methodological knowledge of the development of architectures for complex IT systems in consulting both for enterprise architecture and software development.
The purpose of Enterprise Architecture (EA) is the documentation of relevant information at various levels of an enterprise; such as strategies, business processes, the IT application landscape and the IT infrastructure.
Linking this information across levels helps to gain a better understanding of the relationships between levels. For example, it provides insight into which business processes are supported by which software applications or which projects will change what part of the IT application landscape. Tools for the analysis and visualization of these relationships support decision makers and designers both in business and IT.
Enterprise Architecture Management (EAM) deals with the long-term planning of IT and how IT is best aligned with the business goals of an enterprise. It enables the goal-oriented designed and control of IT projects so that a continuous evolution towards the best IT support for business needs is possible.
Flexibility is one of the most important requirements of modern business information systems; systems are required to be quickly and inexpensively adaptable to new or changing business processes. Model-driven software development (MDSD) meets the demand for increased flexibility through the use of modeling and generator technology. However, model-driven approaches are only slowly gaining importance in practical application for a number of reasons:
