Companies operating in a dynamic environment need to continuously adapt their information systems to changing business processes and associated information needs. Viewed from a microperspective, business users are managing and executing business processes with standard enterprise resource planning systems (ERPs) based on service-oriented architectures on a daily basis but are often not able to adapt the software they use to their individual needs and working practices. This chapter presents the development and evaluation of a prototypic environment that enables users to create enterprise widgets, such as enterprise mash-ups, with tailorability (i.e., they can be tailored to the users’ personal information needs), without the users needing programming knowledge. This environment allows the mashing up of enterprise resources via a lightweight visual-design technique. The evaluation of the prototype in business contexts indicates its usefulness and usability.
