Business users need to analyse changing sets of information to effectively support their working tasks. Due to the complexity of enterprise systems and available tools, especially technically unskilled users face considerable challenges when trying to flexibly retrieve needed data in an ad-hoc manner. As a consequence, available data is limited to(More)
The need to involve business users in process modeling is largely perceived in the context of Business Process Management systems. This can facilitate the elaboration of consistent process models which are better turned to users' needs and organizational changes. Despite the variety of tools and notations, process modeling remains hardly accessible for(More)
Letting end users tailor business processes can result in business process management support, which is better turned to users' needs and organizational changes. However, such tailoring requires not only the users' domain expertise but also advanced skills in computer use, which business users mostly lack. The paper presents the design of the Collaborative(More)
A review is given on the theory of vortex-glass phases in impure type-II superconductors in an external field. We begin with a brief discussion of the effects of thermal fluctuations on the spontaneously broken U (1) and translation symmetries, on the global phase diagram and on the critical behaviour. Introducing disorder we restrict ourselves to the(More)
Enterprises face the challenge of managing underspecified, human-centric business processes, which are executed in distributed teams in a rather informal, ad-hoc manner. This gave hibernating CSCW and ad-hoc workflow research a new push recently. However, there is still the need to clearly perceive end users as the actual drivers of business processes and(More)
This position paper presents research on End-User Development (EUD) for enterprise systems, which is aiming at improving the ability of Small and Medium Enterprises (SMEs) to adapt their software systems to individual and changing needs. These research efforts can be divided into two main directions: process-centric EUD and data-centric EUD. In particular,(More)
Enterprises are constantly struggling to optimize their business processes in order to gain competitive advantage and to survive in the fast evolving global market. Often, the only ones to understand the matter and complexity of these processes are the people, who actually execute them. This raises the need for novel business process management approaches,(More)
