title = "Dynamic resiliency to changes",
abstract = "{\textcopyright} Springer-Verlag Italia Srl 2011.Nowadays IT systems are undergoing an irreversible evolution: we face a socio-technical system where humans are not just {\textquoteleft}{\textquoteleft}users{\textquoteright}{\textquoteright} but decision makers whose decisions determine the behavior of the system as a whole. These decisions will not necessarily be system supported, nor planned in advance and sometimes not even informed, but they will nonetheless be taken. Thus, the inclusion of humans as decision makers requires the provision of technical means so that organizations can balance the need of getting the work done in presence of changes to the original course of action without incurring each and every time the risk of unforeseen toxic over-entitlements. In this paper, we consider a particular case of change to the course of action that is when the users availability or the assignment of privileges to users changes. When such changes occur the satisfaction of organizational business goals can no longer be guaranteed: in fact business goals are achieved through the execution of organizational business process activities and if there are no user that can execute the activities or users with the right privileges and responsibilities, business goals cannot be satisfied. We refer to this problem as dynamic resiliency to changes in the assignment of users to roles.",
