Goal-oriented strategic modelling for Cancer Care in Systems of Systems context using the i* framework
Authors : Suhair AlHajHassan, Mohammed Odeh, Stewart Green, Asem Mansour
Abstract : Cancer Care is considered as a System of Systems (SoS) which results from the collaboration of a set of independent socio and technical constituent systems, largely driven by stakeholders’ needs and goals at multiple levels in a cancer care organisation taking into consideration SoS high-level goals and the constituent systems-level individual goals. It’s challenging to manage these goals specially in such complex large-scale SoS arrangement. However, Goal-Oriented Requirements Engineering (GORE) is considered a promising approach in SoS context to adopt in order to identify, model and manage goals achieved by the overall SoS and its constituent systems. This paper is aimed at investigating the implications of using GORE approaches, and in particular the i* framework to model Cancer Care goals in SoS context. We propose a new process to extract i* elements and concepts from existing user documentation, a "Goals Referential Integrity (GRI)" model that is aimed at maintaining the integrity and consistency of both the SoS-level goals and the constituent systems-level goals, and a proposed i* Cancer Care Goal-Oriented model in Systems of Systems context applied to the Admission, Discharge, and Transfer (ADT) cross-sectional organisational processes of King Hussein Cancer Centre in Jordan.

A semantically enriched goal-oriented referential integrity model in systems of systems context
Authors : Suhair AlHajHassan, Mohammed Odeh, Stewart Green, Asem Mansour
Abstract : System of Systems (SoS) results from the collaboration of a set of independent socio and technical constituent systems, largely driven by stakeholders' needs and goals taking into consideration SoS high-level goals and the constituent systems-level individual goals. It's challenging to manage the satisfaction of these goals in such large and complex SoS arrangement, where links between these goals may not be clearly known or specified. Additionally, competing stakeholders' interests and goals establish a complex stakeholder environment. In this research the i* goal-oriented framework has been utilised in SoS context to identify, model and manage goals of the overall SoS and its constituent systems. This paper discusses a novel Goals Referential Integrity (GRI) model that is aimed at maintaining the integrity and consistency of both the SoS-level and the constituent systems-level goals, in an attempt to address the current challenges of managing goals in an SoS arrangement. Furthermore, an ontology-based model has been developed to (1) support the GRI model and semantically annotates goals' levels in SoS context, and (2) specify the relationships and linkages between the SoS organisation, its constituent systems, global and local goals, and strategic and policy documents. Together the GRI model and its associated ontology model form the Semantic Goal Referential Integrity (SGRI) applied in SoS context, where conflicts between goals at the SoS and the constituent systems levels can be discovered in an attempt to maintain the semantic integrity of the SoS and constituent systems goals

An ontology-based i* goal-oriented referential integrity model in systems of systems context.
Authors : Suhair AlHajHassan, Mohammed Odeh, Stewart Green, Asem Mansour
Abstract : System of Systems (SoS) results from the integration of a set of independent Constituent Systems (CS) that could be socio or technical, in order to offer unique functionalities. SoS is largely driven by stakeholders’ needs and goals taking into consideration SoS-level global goals and CS-level individual goals. It’s challenging to manage the satisfaction of these goals in such complex SoS arrangements, where links between these goals may not be clearly known or specified, and competing goals establish a complex stakeholder environment. In this research the i* goal-oriented framework has been utilised in SoS context to identify, model and manage goals of the overall SoS and its constituent systems. This paper discusses a novel Goals Referential Integrity (GRI) model that is intended to maintain the integrity and consistency of both the SoS-level and the CS-level goals, in an attempt to address the current challenges of managing goals in an SoS arrangement. Furthermore, an ontology-based model has been developed to support the GRI model and semantically annotate goals’ levels in SoS context, specify the relationships and linkages between the SoS organisation, its constituent systems, global and local goals, and strategic and policy documents. Together the GRI model and its associated ontology model form the Semantic Goals Referential Integrity (SGRI) applied in SoS context, where conflicts between goals at the SoS and the CS-levels can be discovered in an attempt to maintain the semantic integrity of the SoS and CS goals.

A Semantically-Enriched Goal-Oriented Requirements Engineering Framework for Systems of Systems Using the i* Framework Applied to Cancer Care (OntoSoS. GORE)
Authors : Suhair AlHajHassan
Abstract : In recent years, monolithic systems are being composed into bigger systems as Systems of Systems (SoSs). This evolution of SoS raises several software engineering key challenges, such as the management of emerging inconsistent goals and requirements, which may occur among the various Constituent Systems (CSs) themselves, as well as between the entire SoS and the participating CSs. Another significant challenge is that Systems of Systems

An Adapted Ontology for a Generalized Riva-Driven Business Process Architecture
Authors : Ahmad Samhan, Suhair AlHajHassan
Abstract : Riva is a Business Process Architecture (BPA) modelling approach that has been used to model key business processes for specific organizational boundaries based on the brainstorming of Essential Business Entities (EBEs). During its early stages, Riva relies heavily on brainstorming the EBEs from stakeholders. However, it does not provide a systematic process for deriving generalized BPA models from multiple heterogeneous sources. Furthermore, when deriving processes from the identified Riva-EBEs, Riva identifies Case Processes (CPs), Case Management Processes (CMPs), and Case Strategy Processes (CSPs). However, the Riva literature mainly supports modelling the CPs, CMPs, and the relationships between them. It does not focus on modelling the CSPs nor their related relationships. Accordingly, Riva has been semantically-enriched by the srBPA ontology component. But this semantic …

Adapting Riva to Support Case Strategy Processes and Enable Modeling a Generalized Business Process Architecture
Authors : Ahmad Samhan, Suhair AlHajHassan, Mohammed Odeh
Abstract : Riva is a business process architecture (BPA) modeling approach that has been used within the software engineering domain to model key business processes for specific organizational boundaries. Also, Riva is mainly a facilitated approach that relies heavily on interactions with stakeholders to determine the key entities that constitute the foundation of modeling a BPA-of-interest, especially in its early stages. Accordingly, Riva is not considered an independent approach (without heavy interaction with stakeholders), nor is it applied to support the derivation of generalized BPA models from multiple heterogeneous sources. Furthermore, while deriving business processes from the identified Riva entities, Riva is anticipated to identify and model Case Processes (CPs), Case Management Processes (CMPs), and Case Strategy Processes (CSPs) and their interrelationships. However, the Riva approach proposed in the literature mainly supports modeling CPs, CMPs, and their interrelationships, and lacks the support of modeling the CSPs, nor their related relationships. To address the limitations mentioned above, this paper presents an adaptation to the Riva-BPA modeling approach that enables modeling of a generalized BPA from multiple heterogeneous sources. In addition, this adaptation facilitates the identification of business processes not only based on the direct interaction with stakeholders but also by utilizing independent elicitation techniques of entities. Moreover, this paper extends Riva to model the corresponding CSPs and their related relationships. The proposed adaptation has been evaluated by experts in the domains of business process modeling and software engineering.
