    A goal-oriented requirements modelling language for enterprise architecture

    Methods for enterprise architecture, such as TOGAF, acknowledge the importance of requirements engineering in the development of enterprise architectures. Modelling support is needed to specify, document, communicate and reason about goals and requirements. Current modelling techniques for enterprise architecture focus on the products, services, processes and applications of an enterprise. In addition, techniques may be provided to describe structured requirements lists and use cases. Little support is available however for modelling the underlying motivation of enterprise architectures in terms of stakeholder concerns and the high-level goals that address these concerns. This paper describes a language that supports the modelling of this motivation. The definition of the language is based on existing work on high-level goal and requirements modelling and is aligned with an existing standard for enterprise modelling: the ArchiMate language. Furthermore, the paper illustrates how enterprise architecture can benefit from analysis techniques in the requirements domain

    An enterprise architecture framework for electronic requirements information management

    © 2017 Elsevier LtdManaging information about client requirements effectively can contribute to improve the quality of built facilities, and their related services. However, the process has been challenging to construction project management often resulting in failed projects. This necessitates an overwhelming need for a better approach. This paper presents a novel enterprise architecture framework for managing information about client requirements across all phases of a construction project and through-life of a built facility. The Integrated electronic Requirements Information Management Framework (eRIM) defines an information-centric, and process and service-oriented enterprise architecture approach to requirements management. It also describes how Information and Communication Technology (ICT)/Information Systems (IS) can support this information management. In developing the framework, findings from three case study projects were collated through observations, a questionnaire and interviews of construction practitioners. It is concluded that when implemented and incorporated in the management of construction projects, the eRIM architecture framework can potentially contribute towards improved and more efficient and effective management of client requirements across all stages of a project. Further work is outlined to operationalize the framework

    Model driven validation approach for enterprise architecture and motivation extensions

    As the endorsement of Enterprise Architecture (EA) modelling continues to grow in diversity and complexity, management of its schema, artefacts, semantics and relationships has become an important business concern. To maintain agility and flexibility within competitive markets, organizations have also been compelled to explore ways of adjusting proactively to innovations, changes and complex events also by use of EA concepts to model business processes and strategies. Thus the need to ensure appropriate validation of EA taxonomies has been considered severally as an essential requirement for these processes in order to exert business motivation; relate information systems to technological infrastructure. However, since many taxonomies deployed today use widespread and disparate modelling methodologies, the possibility to adopt a generic validation approach remains a challenge. The proliferation of EA methodologies and perspectives has also led to intricacies in the formalization and validation of EA constructs as models often times have variant schematic interpretations. Thus, disparate implementations and inconsistent simulation of alignment between business architectures and heterogeneous application systems is common within the EA domain (Jonkers et al., 2003). In this research, the Model Driven Validation Approach (MDVA) is introduced. MDVA allows modelling of EA with validation attributes, formalization of the validation concepts and transformation of model artefacts to ontologies. The transformation simplifies querying based on motivation and constraints. As the extended methodology is grounded on the semiotics of existing tools, validation is executed using ubiquitous query language. The major contributions of this work are the extension of a metamodel of Business Layer of an EAF with Validation Element and the development of EAF model to ontology transformation Approach. With this innovation, domain-driven design and object-oriented analysis concepts are applied to achieve EAF model’s validation using ontology querying methodology. Additionally, the MDVA facilitates the traceability of EA artefacts using ontology graph patterns

    Using goals to model strategy map for business IT alignment

    Strategy Map (SM) is one of the widely used methods to create business aligned IT strategy map providing valuable insights to business executives. However, problem with strategy map method is that it is not easy to use which can lend itself to various interpretations. This is because linkages between the strategic objectives in the four strategy map perspectives are not explicit which makes SM ambiguous. Goal modelling approaches from Requirements Engineering (RE) have proven rigorous in elicitation and representation of information system requirements. In an attempt to make explicit the causal relationships of SM linkages meaningful this research proposes the use of goal modelling approach i*

    From Conceptual Modelling to Requirements Engineering

    No full text
    International audienceConceptual modelling is situated in the broader view of information systems requirements engineering. Requirements Engineering (RE) explores the objectives of different stakeholders and the activities carried out by them to meet these objectives in order to derive purposeful system requirements and therefore lead to better quality systems i.e. systems that meet the requirements of their users. Thus RE product models use concepts for modelling these instead of concepts like data, process, events etc. used in conceptual models. Since the former are more stable than the latter, requirements engineering manages change better. The paper gives the rationale for extending traditional conceptual models and introduces some RE product models. Furthermore, in contrast to conceptual modelling, requirements engineering lays great stress on the engineering process employed. The paper introduces some RE process models and considers their effect on tool support

    Challenges for Model-Driven Development of Strategically Aligned Information Systems

    Full text link
    [EN] Model-Driven Development (MDD) has been proposed as an alternative to the traditional development of information systems, given its ability to integrate different stakeholders into the information system engineering process. Currently, longtime researched MDD methods and modern no-code and low-code platforms support the generation of the working code of the information system and services. However, in today's continuously changing environment, organisations need to align the information systems and services with the business structure, strategy, and processes they support. This article shows the design challenges for integrating business strategy information into a model-driven development method. We applied a set of mechanism experiments on an MDD method composed of three modelling frameworks with demonstrated semantic consistency, that covers the organisational, business process, and information system levels to identify information loss and transformation coverage issues that prevent the generation of information systems and services that are strategically aligned. The challenges were discussed with experts, confirming the relevance of avoiding the overlapping between the strategic and business process concepts, providing organisational-level constructs to express strategic ends and means, and considering the organisational structure in the modular design of business process and information systems and services.This work was supported in part by the Spanish State Research Agency and the Generalitat Valenciana under Project MICIN/AEI/10.13039/501100011033, Project GV/2021/072, and Project INNEST/2021/57 by Agencia Valenciana de Innovacion (AVI); in part by the European Regional Development Fund (ERDF), the European Union Next Generation, and Plan de Recuperacion, Transformacion y Resiliencia (PRTR); and in part by the National Agency for Research and Development (ANID)/Scholarship Program/Doctorado Becas Chile under Grant 2020-72210494.Noel-Lopez, R.; Panach, JI.; Pastor López, O.
