Software-as-a-Service applications commonly consolidate multiple businesses into the same database to reduce costs. This practice makes it harder to implement several essential features of enterprise applications. The first is support for master data, which should be shared rather than replicated for each tenant. The second is application modification and extension, which applies both to the database...
In today's rapidly changing and highly competitive operating contexts, businesses are increasingly seeking cooperative, long-term inter-organizational relationships. Inter-organizational systems (IOS) are major enablers of inter-organizational cooperation. Drawing upon transaction costs economics theory and resource-based view as the theoretical frames, this study presents electronic cooperation value...
Today, the management of service quality poses a major challenge for many service providers and their business customers. We argue that the trade-off between service cost and benefit incurred by both parties is not sufficiently considered when service quality is stipulated. Up to now, neither in practice nor in academia a commonly accepted engineering approach exists to determine business-relevant...
While several role-related concepts play an important role in business modeling, their definitions, relations, and use differ greatly between languages, papers, and reports. Due to this, the knowledge captured by models is not transferred correctly, and models are incomparable. In this paper, we provide a meta-model and definitions for several role-related concepts based on the practice of existing...
The aim of this paper is to propose a business model for a Service and Application provider acting as an intermediary within a regional healthcare ecosystem in the UK. The paper describes the development of Software-as-a-Service Utility (SaaS-U) business model to deliver services and applications and the implications of its use with selected healthcare scenarios. This paper is part of ongoing research...
Requests for changes to software systems have a potential damaging effect on software projects and the life span of software. Changes can not be avoided since it seems impossible to produce complete, correct and stable requirements. Late requests for deep, structural software changes are particularly harmful. We present an approach for early detection of evolutionary changes of software requirements,...
The field of requirements engineering for business processes has grown during the last several years. As business processes are assumed to fulfil organizational goals, goal models could be transformed into business process models that specify how business processes fulfil the organizational goals. Although both the fields of Goal-Oriented RE (GORE) and Business Process Management (BPM) received a...
Models of different kinds are used in the area of business process management. Abstract process knowledge as well as executable process definitions can be visualized and edited in a graphical manner. The same holds true for models of process instances in some process-aware information systems (PAIS), which allow for dynamic modifications in a process instance during process runtime. An appropriate...
