This paper aims at analyzing the category of multi-tiered proxy design problems, where end-user developers do not necessarily coincide with the actual end users of the system, but can be considered as end users’ proxies. This situation can be found in a variety of application domains, from home automation, where electricians defining home automation systems for energy saving are different from house occupants, to e-government, where administrative employees creating e-government services are different from citizens using those services. The analysis leads to the definition of a new interaction and co-evolution model, called ICE2, which, on the basis of the model discussed in a previous work, considers not only the case of end users that directly make their system evolve by means of end-user development activities, but also the case where a proxy figure is present, namely an expert in the application domain that creates and modifies software artifacts for others (the actual end users). Finally, a design approach is proposed, which aims at generalizing the solutions suggested in different application domains, and at sustaining the interaction and co-evolution processes that involve end users, end-user developers, and systems.

Abstract
This paper aims at analyzing the category of multi-tiered proxy design problems, where end-user developers do not necessarily coincide with the actual end users of the system, but can be considered as end users’ proxies. This situation can be found in a variety of application domains, from home automation, where electricians defining home automation systems for energy saving are different from house occupants, to e-government, where administrative employees creating e-government services are different from citizens using those services. The analysis leads to the definition of a new interaction and co-evolution model, called ICE2, which, on the basis of the model discussed in a previous work, considers not only the case of end users that directly make their system evolve by means of end-user development activities, but also the case where a proxy figure is present, namely an expert in the application domain that creates and modifies software artifacts for others (the actual end users). Finally, a design approach is proposed, which aims at generalizing the solutions suggested in different application domains, and at sustaining the interaction and co-evolution processes that involve end users, end-user developers, and systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
