By the term ‘professional end-user developers’ is meant professionals working in a highly technical, knowledge-rich domain who develop their own software in order to further their professional work. I have conducted empirical studies of such developers working in the domains of financial mathematics ([1], [2]), earth and space sciences ([2], [3]), and, currently, structural biology. These devel...

The negotiation of Service Level Agreements for composite web services is a very complex process. It involves the coordination of the negotiation process so that the end-to-end QoS requirements of the user request are satisfied while ensuring that the atomic QoS requirements are also simultaneously satisfied.

Chargeback systems in an end user computing (EUC) environment were evaluated in an empirical survey of 16 organizations and 151 end users. The organizations were classified into six EUC chargeback system groups according to the extent of operation, development and investment costs absorbed in overhead, EDP-department control over microcomputer purchases and end user involvement in EUC budgeting...

Further, user (UI) designers struggle adapt their UIs evolving needs preferences. In order address these issues, we want support end users in designing own interfaces. However, end-user UI represents a major challenge, given that often lack necessary skill...

“Cloud” computing – a relatively recent term, builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. It implies a service oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, on-demand services and many other things. This pa...

Exception management is a critical design function of organizational information systems (IS) whose effectiveness relies, in large part, on end-user decision-making about how to proceed.
