The outcome is a resource-aware process model .…”

A template-based approach for responsibility management in executable business processes

Process-oriented organisations need to manage the different types of responsibilities their employees may have w.r.t. the activities involved in their business processes. Despite several approaches provide support for responsibility modelling, in current Business Process Management Systems (BPMS) the only responsibility considered at runtime is the one related to performing the work required for activity completion. Others like accountability or consultation must be implemented by manually adding activities in the executable process model, which is time-consuming and error-prone. In this paper, we address this limitation by enabling current BPMS to execute processes in which people with different responsibilities interact to complete the activities. We introduce a metamodel based on Responsibility Assignment Matrices (RAM) to model the responsibility assignment for each activity, and a flexible template-based mechanism that automatically transforms such information into BPMN elements, which can be interpreted and executed by a BPMS. Thus, our approach does not enforce any specific behaviour for the different responsibilities but new templates can be modelled to specify the interaction that best suits the activity requirements. Furthermore, libraries of templates can be created and reused in different processes. We provide a reference implementation and build a library of templates for a well-known set of responsibilities.

“…A graphical notation with a similar expressive power than RAL (RALph) was designed to allow for graphically defining resource assignments in process models (Cabanillas et al 2015a). Similarly to the case of RAL, RALph is not actually equipped with support for modelling specific responsibilities.…”

“…Some meta-models like [32,33] and an expressive resource assignment language [5] have been developed. Among those, Resource Assignment Language graPH (RALPH) [5] provides a graphical representation of the resource selection conditions and assignments. RALPH has formal semantics, which makes it appropriate for automated resource analysis in business process models.…”

Abstract:The trustworthiness of systems that support complex collaborative business processes is an emergent property. In order to address users' trust concerns, trustworthiness requirements of software systems must be elicited and satisfied. The aim of this paper is to address the gap that exists between end-users' trust concerns and the lack of implementation of proper trustworthiness requirements. New technologies like cloud computing bring new capabilities for hosting and offering complex collaborative business operations. However, these advances might bring undesirable side effects, e.g., introducing new vulnerabilities and threats caused by collaboration and data exchange over the Internet. Hence, users become more concerned about trust. Trust is subjective; trustworthiness requirements for addressing trust concerns are difficult to elicit, especially if there are different parties involved in the business process. We propose a user-centered trustworthiness requirement analysis and modeling framework. We integrate the subjective trust concerns into goal models and embed them into business process models as objective trustworthiness requirements. Business process model and notation is extended to enable modeling trustworthiness requirements. This paper focuses on the challenges of elicitation, refinement and modeling trustworthiness requirements. An application example from the healthcare domain is used to demonstrate our approach.

“…Business process models are frequently used in software development for understanding the behavior of the users, their requirements and for the assignment of requirements to particular well-defined business process elements. In business processes, resources are either human or non-human assets, e.g., software, apps or IT devices [3]. Non-human assets can provide either fully-automated or semi-automated support to the activity performers.…”

The trustworthiness of systems that support complex collaborative business processes is an emergent property. In order to address users' trust concerns, trustworthiness requirements of software systems must be elicited and satisfied. The aim of this paper is to address the gap that exists between end-users' trust concerns and the lack of implementation of proper trustworthiness requirements in software systems. We focus on the challenges of specifying trustworthiness requirements and integrating them into the software development process as business process models. This paper provides a conceptual model of our approach by extending Business Process Model and Notation (BPMN) for integrating trustworthiness requirements. Our proposed approach explicitly considers the trustworthiness of individual components as part of the business process models. We use an application example from the health care domain to demonstrate our approach.
