Towards a framework for improving goal-oriented requirement models quality

Goal-orientation is a widespread and useful approach to Requirements Engineering. However, quality assessment frameworks focused on goal-oriented processes are either limited or remain on the theoretical side. Requirements quality initiatives range from simple metrics applicable to requirements documents, to general-purpose quality frameworks that include syntactic, semantic and pragmatic concerns. In some recent works, we have proposed a metrics framework for goal-oriented models, but the approach did not cover the cycle of quality assessment. In this paper we present a semiotic-based quality assessment proposal built upon the i* framework and the SEQUAL proposal. We propose a simplification of SEQUAL which can be applied to i* models by defining semantic, pragmatic and social metrics. As a result, we obtain suites of metrics that can be applied to i* goal-oriented requirements models. This theoretical work is put into practice by using iStarML, a XML representation of i* models, over which XQuery sentences compute the proposed metrics.Peer ReviewedPostprint (published version

Translating stakeholders needs to application requirements for e-government development projects

Most public organizations nowadays undertake implementations of e-government projects. Such projects are usually the organization’s response to its operational needs. Sometimes though, they are linked to a wider perspective or central planning initiative sponsored by a government and involving a large number of public service organizations. In their majority e-government projects aim at addressing citizens’ and businesses’ needs in their interaction with public authorities. Thus such projects directly reflect public administration’s mission as it is defined with reference to its external environment. In addition public administration stakeholder requirements are examined, with compatibilities and / or conflicts and their effects on the design of e-Government implementations identified. This can be used in resolving conflicting requirements at a higher level before the design and implementation of individual components of a system that correspond to tasks and procedures are affected

MAPPING E-GOVERNMENT STAKEHOLDER REQUIREMENTS TO PUBLIC ADMINISTRATION OPERATIONAL NEEDS

This paper proposes a framework for e-government development projects aiming at the detection of inconsistencies, incompatibilities and mistakes during the early design stages. This is achieved by applying a Requirements Engineering methodology for the identification of stakeholder requirements and dependencies. Furthermore, a generic identification of public administration’s functions is being proposed making it possible to detect deficits in service provision. Using a Goal Oriented Requirements Engineering methodology and relevant tools, stakeholders’ and functional goals are mapped. An example of a knowledge management system, presenting the case of a Greek e-government application is discussed here in relation to the proposed framework

Emergency Response Information System Interoperability: Development of Chemical Incident Response Data Model

Emergency response requires an efficient information supply chain for the smooth operations of intra- and inter-organizational emergency management processes. However, the breakdown of this information supply chain due to the lack of consistent data standards presents a significant problem. In this paper, we adopt a theory- driven novel approach to develop an XML-based data model that prescribes a comprehensive set of data standards (semantics and internal structures) for emergency management to better address the challenges of information interoperability. Actual documents currently being used in mitigating chemical emergencies from a large number of incidents are used in the analysis stage. The data model development is guided by Activity Theory and is validated through a RFC-like process used in standards development. This paper applies the standards to the real case of a chemical incident scenario. Further, it complies with the national leading initiatives in emergency standards (National Information Exchange Model

Domain ontology analysis in agent-oriented requirements engineering

none2Goal and agent orientation in Requirements Engineering has been recognized as a very promising approach. In fact, by adopting notions as those of Agent, Goal, Intentional Dependency and so on, it is possible to smoothly re ne high-level requirements into detailed descriptions of the system-to-be. This paper introduces a requirements engineering framework based on the notions of Agent, Goal, and Intentional Dependency. The framework represents a powerful tool for describing the organization ontology and capture high-level organizational needs, to transform them into system requirementsPaolo Donzelli; Paolo BrescianiPaolo, Donzelli; Bresciani, Paol
