A Reference Framework for Advanced Flexible Information Systems.

The nature of information systems is currently going through a major transition. In the past, information systems managing ‘physical processes’ and systems managing ‘administrative processes’ would usually be separated in two different ‘worlds’. Now, we see that these worlds need to be tightly coupled or even integrated to deal with developments like the transformation of supply chains to demand chains, just-in-time logistics, servitization and mass-customization of products and services. This causes confusion, as positioning systems and approaches underlying these systems with respect to each other is not easy. Improper positioning may in turn lead to blind spots in system functionality - resulting in the inability to properly support the entire spectrum of business functionality - or replication of functionality - usually resulting in inconsistency of functionality and data. To address this issue, this paper presents a reference framework for advanced flexible information systems, in which existing systems and approaches can be positioned, analyzed and compared. The framework is based on a concept of multi-layer, bimodal flexibility. We apply this framework on a small but representative set of research and development efforts for advanced flexible information systems.
