    An Ontology for Product-Service Systems

    Get PDF
    Industries are transforming their business strategy from a product-centric to a more service-centric nature by bundling products and services into integrated solutions to enhance the relationship between their customers. Since Product- Service Systems design research is currently at a rudimentary stage, the development of a robust ontology for this area would be helpful. The advantages of a standardized ontology are that it could help researchers and practitioners to communicate their views without ambiguity and thus encourage the conception and implementation of useful methods and tools. In this paper, an initial structure of a PSS ontology from the design perspective is proposed and evaluated

    A Model-Driven Architecture Approach to the Efficient Identification of Services on Service-oriented Enterprise Architecture

    No full text
    Service-Oriented Enterprise Architecture requires the efficient development of loosely-coupled and interoperable sets of services. Existing design approaches do not always take full advantage of the value and importance of the engineering invested in existing legacy systems. This paper proposes an approach to define the key services from such legacy systems effectively. The approach focuses on identifying these services based on a Model-Driven Architecture approach supported by guidelines over a wide range of possible service types

    Using real options to select stable Middleware-induced software architectures

    The requirements that force decisions towards building distributed system architectures are usually of a non-functional nature. Scalability, openness, heterogeneity, and fault-tolerance are examples of such non-functional requirements. The current trend is to build distributed systems with middleware, which provide the application developer with primitives for managing the complexity of distribution, system resources, and for realising many of the non-functional requirements. As non-functional requirements evolve, the `coupling' between the middleware and architecture becomes the focal point for understanding the stability of the distributed software system architecture in the face of change. It is hypothesised that the choice of a stable distributed software architecture depends on the choice of the underlying middleware and its flexibility in responding to future changes in non-functional requirements. Drawing on a case study that adequately represents a medium-size component-based distributed architecture, it is reported how a likely future change in scalability could impact the architectural structure of two versions, each induced with a distinct middleware: one with CORBA and the other with J2EE. An option-based model is derived to value the flexibility of the induced-architectures and to guide the selection. The hypothesis is verified to be true for the given change. The paper concludes with some observations that could stimulate future research in the area of relating requirements to software architectures

    Data in Business Process Models. A Preliminary Empirical Study

    Get PDF
    Traditional activity-centric process modeling languages treat data as simple black boxes acting as input or output for activities. Many alternate and emerging process modeling paradigms, such as case handling and artifact-centric process modeling, give data a more central role. This is achieved by introducing lifecycles and states for data objects, which is beneficial when modeling data-or knowledge-intensive processes. We assume that traditional activity-centric process modeling languages lack the capabilities to adequately capture the complexity of such processes. To verify this assumption we conducted an online interview among BPM experts. The results not only allow us to identify various profiles of persons modeling business processes, but also the problems that exist in contemporary modeling languages w.r.t. The modeling of business data. Overall, this preliminary empirical study confirms the necessity of data-awareness in process modeling notations in general

    Measuring Process Modelling Success

    Get PDF
    Process-modelling has seen widespread acceptance, par ticularly on large IT-enabled Business Process Reengineering projects. It is applied, as a process design and management technique, across all life-cycle phases of a system. While there has been much research on aspects of process-modelling, little attention has focused on post-hoc evaluation of process-modelling success. This paper addresses this gap, and presents a process-modelling success measurement (PMS) framework, which includes the dimensions: process-model quality; model use; user satisfaction; and process modelling impact. Measurement items for each dimension are also suggested

    An Approach to Transform Public Administration into SOA-based Organizations

    Get PDF
    Nowadays, Service-Oriented Architectures (SOA) is widely spread in private organizations. However, when transferring this knowledge to Public Administration, it is realized that it has not been transformed in terms of its legal nature into organizations capable to operate under the SOA paradigm. This fact prevents public administration bodies from offering the efficient services they have been provided by different boards of governments. A high-level framework to perform this transformation is proposed. Taking it as starting point, an instance of a SOA Target Meta-Model can be obtained by means of an iterative and incremental process based on the analysis of imperatives and focused on the particular business context of each local public administration. This paper briefly presents a practical experience consisting in applying this process to a Spanish regional public administration.Junta de Andalucía TIC-578

    Kite-marks, standards and privileged legal structures; artefacts of constraint disciplining structure choices

    Get PDF
    As different countries and regions continue to develop policy and legal frameworks for social enterprises this paper offers new insights into the dynamics of legal structure choice by social entrepreneurs. The potential nodes of conflict between exogenous prescriptions and social entrepreneur’s own orientation to certain aspects of organization and what social entrepreneurs actually do in the face of such conflict is explicated. Kite-marks, standards and legal structures privileged by powerful actors are cast as political artefacts that serve to discipline the choices of legal structure by social entrepreneurs as they prescribe desirable characteristics, behaviours and structures for social enterprises. This paper argues that social enterprises should not be understood as the homogenous organisational category that is portrayed in government policy documents, kite-marks and privileged legal structures but as organisations facing a proliferation of structural forms which are increasingly rendered a governable domain (Nickel & Eikenberry, 2016; Scott, 1998) through the development of kite marks, funder / investor requirements and government policy initiatives. Further, that these developments act to prioritise and marginalise particular forms of social enterprises as they exert coercive, mimetic and normative pressures (DiMaggio & Powell, 1983) that act to facilitate the categorising of social enterprises in a way that strengthens institutional coherence and serves to drive the structural isomorphism (Boxenbaum & Jonsson, 2017; DiMaggio & Powell, 1983) of social enterprise activity. Whilst the actions of powerful actors work to maintain (Greenwood & Suddaby, 2006) the social enterprise category the embedded agency of social entrepreneurs acts to transform it (Battilana, Leca, & Boxenbaum, 2009). The prevailing Institutional logics (Ocasio, Thornton, & Lounsbury, 2017; Zhao & Lounsbury, 2016) that serve to both marginalise and prioritise those legal structures are used to present argument that the choice of legal structure for a social enterprise is often in conflict with the social entrepreneur's orientation to certain aspects of how they wish to organise. Where the chosen legal structure for a social enterprise is in conflict with the social entrepreneur's own organising principles as to how they wish to organise then this can result in the social entrepreneur decoupling (Battilana, Leca, & Boxenbaum, 2009) their business and/or governance practices from their chosen legal structure in order to resolve the tensions that they experience. Social entrepreneurs also experiencing the same tension enact a different response in that they begin to create and legitimate new legal structures on the margins of the social enterprise category through a process of institutional entrepreneurship (Battilana, Leca, & Boxenbaum, 2009; Hardy & Maguire, 2017)
