The Theory of Corporate Information Systems

Abstract

The paper introduces a new discipline that combines the design of information systems, databases, programming, as well as project and change management, called the theory of corporate information systems. The content of each area correlates with the levels of software implementation: processes, data, application, technology as well as the project and changes. The theory assumes the formalization of strategies for analysis, design, roles and authorization, technical and business cutover, change management, build, data migration, training, testing and post go-live support, each of which is decomposed into subtasks, consistent with other activities, and then planned for execution. Planning plays a key role during the implementation of corporate information systems, since most of the project tasks involve receiving feedback from future users of the system. Thus, the proposed theory combines the existing technical disciplines and expands the scope of their application to larger-scale IT projects.
