Defining business process flexibility with the help of invariants

Gil Regev, Alain Wegmann

Enterprise survival is about maintaining an identity that is separate from other enterprises. We define flexibility as the ability to change without losing identity. The identity of an enterprise can be analyzed as a set of norms and beliefs about these no ...

On the Cost of Modularity in Atomic Broadcast

André Schiper, Sergio Mena, Nils Richard Ekwall, Olivier Rütti

Modularity is a desirable property of complex software systems, since it simplifies code reuse, verification, maintenance, etc. However, the use of loosely coupled modules introduces a performance overhead. This overhead is often considered negligible, but ...
