    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

    The world of machine-to-machine (M2M) communication is gradually moving from vertical single purpose solutions to multi-purpose and collaborative applications interacting across industry verticals, organizations and people - A world of Internet of Things (IoT). The dominant approach for delivering IoT applications relies on the development of cloud-based IoT platforms that collect all the data generated by the sensing elements and centrally process the information to create real business value. In this paper, we present a system that follows the Fog Computing paradigm where the sensor resources, as well as the intermediate layers between embedded devices and cloud computing datacenters, participate by providing computational, storage, and control. We discuss the design aspects of our system and present a pilot deployment for the evaluating the performance in a real-world environment. Our findings indicate that Fog Computing can address the ever-increasing amount of data that is inherent in an IoT world by effective communication among all elements of the architecture

    Human Resource and Employment Practices in Telecommunications Services, 1980-1998

    [Excerpt] In the academic literature on manufacturing, much research and debate have focused on whether firms are adopting some form of “high-performance” or “high-involvement” work organization based on such practices as employee participation, teams, and increased discretion, skills, and training for frontline workers (Ichniowski et al., 1996; Kochan and Osterman, 1994; MacDuffie, 1995). Whereas many firms in the telecommunications industry flirted with these ideas in the 1980s, they did not prove to be a lasting source of inspiration for the redesign of work and employment practices. Rather, work restructuring in telecommunications services has been driven by the ability of firms to leverage network and information technologies to reduce labor costs and create customer segmentation strategies. “Good jobs” versus “bad jobs,” or higher versus lower wage jobs, do not vary according to whether firms adopt a high- involvement model. They vary along two other dimensions: (1) within firms and occupations, by the value-added of the customer segment that an employee group serves; and (2) across firms, by union and nonunion status. We believe that this customer segmentation strategy is becoming a more general model for employment practices in large-scale service | operations; telecommunications services firms may be somewhat more | advanced than other service firms in adopting this strategy because of certain unique industry characteristics. The scale economies of network technology are such that once a company builds the network infrastructure to a customer’s specifications, the cost of additional services is essentially zero. As a result, and notwithstanding technological uncertainty, all of the industry’s major players are attempting to take advantage of system economies inherent in the nature of the product market and technology to provide customized packages of multimedia products to identified market segments. They have organized into market-driven business units providing differentiated services to large businesses and institutions, small businesses, and residential customers. They have used information technologies and process reengineering to customize specific services to different segments according to customer needs and ability to pay. Variation in work and employment practices, or labor market segmentation, follows product market segmentation. As a result, much of the variation in employment practices in this industry is within firms and within occupations according to market segment rather than across firms. In addition, despite market deregulation beginning in 1984 and opportunities for new entrants, a tightly led oligopoly structure is replacing the regulated Bell System monopoly. Former Bell System companies, the giants of the regulated period, continue to dominate market share in the post-1984 period. Older players and new entrants alike are merging and consolidating in order to have access to multimedia markets. What is striking in this industry, therefore, is the relative lack of variation in management and employment practices across firms after more than a decade of experience with deregulation. We attribute this lack of variation to three major sources. (1) Technological advances and network economics provide incentives for mergers, organizational consolidation, and, as indicated above, similar business strategies. (2) The former Bell System companies have deep institutional ties, and they continue to benchmark against and imitate each other so that ideas about restructuring have diffused quickly among them. (3) Despite overall deunionization in the industry, they continue to have high unionization rates; de facto pattern bargaining within the Bell system has remained quite strong. Therefore, similar employment practices based on inherited collective bargaining agreements continue to exist across former Bell System firms

    A taxonomy of asymmetric requirements aspects

    Get PDF
    The early aspects community has received increasing attention among researchers and practitioners, and has grown a set of meaningful terminology and concepts in recent years, including the notion of requirements aspects. Aspects at the requirements level present stakeholder concerns that crosscut the problem domain, with the potential for a broad impact on questions of scoping, prioritization, and architectural design. Although many existing requirements engineering approaches advocate and advertise an integral support of early aspects analysis, one challenge is that the notion of a requirements aspect is not yet well established to efficaciously serve the community. Instead of defining the term once and for all in a normally arduous and unproductive conceptual unification stage, we present a preliminary taxonomy based on the literature survey to show the different features of an asymmetric requirements aspect. Existing approaches that handle requirements aspects are compared and classified according to the proposed taxonomy. In addition,we study crosscutting security requirements to exemplify the taxonomy's use, substantiate its value, and explore its future directions

    An empirical investigation of the channels that facilitate a total quality culture

    Get PDF
    It is generally agreed that the culture of an organisation is a function of its values, beliefs and behavioural practices and that the influence of culture on an organisation is powerful and pervasive. There is also broad agreement that total quality management (TQM ) is a management paradigm that propagates certain values, behaviour and working methods. Moreover, that the successful introduction and practice of a total quality management approach requires close attention to, and more often than not modification of, organisational culture. Yet, culture is somewhat intangible, and regardless of the precise cultural aspirations, in order to change or maintain the desired culture an organisation needs a set of facilitating channels. These are mechanisms or necessary conditions that influence, mould and help sustain a desirable cultural orientation. This paper examines the channels that facilitate the development of a total quality culture based on the findings of an investigation of an international sample of organisations widely regarded as leading exponents of TQM

    Automated Vehicles Have Arrived: What\u27s a Transit Agency to Do?

    Ongoing innovations in automated and connected road vehicles create a path of radical transformation of personal mobility, the automotive industry, trucking, public transit, the taxi industry, urban planning, transportation infrastructure, jobs, vehicle ownership, and other physical and social aspects of our built world and daily lives. In considering automated vehicle (AV) deployments and their cost, as well as the changes in traffic volume, congestion, rights of way, and the complexities of mixed fleets with both automated and non-automated vehicles, the time frame of impacts can only be surmised. Still, it is worth considering a framework for understanding and managing the forthcoming process of change covered in this perspective

    The Measure and Regulation of Competition in Telecommunications Markets

    The development of the canadian telecommunications web is significantly influenced by the regulatory framework put in place to oversee the evolution of the web toward a competitive system. This paper has two specific objectives: first, to develop a methodological framework, which will allow a proper characterization of the level of competition in the telecommunications industry, more specifically in the residential local access market and second, to recommend some (significant) changes in the CRTC approach to the regulation of the Canadian Telecommunications industry. I argue that the current approach to the regulation of telecommunications in Canada is likely to generate significant harms to consumers and businesses as well as efficiency losses for the Canadian economy. I conclude that there is a urgent need for a telecommunications regulatory reform, with a stronger accent put on three crucial roles of the telecommunications regulator as the trusted generator of information for the consumers, as the manager of the level playing field conditions, and as the promoter of efficient investment programmes. Le développement du réseau canadien des télécommunications est influencé de façon significative par le cadre réglementaire adopté pour régir l’évolution de ce réseau vers la concurrence. Cet article a deux objectifs principaux : d’une part, développer un cadre méthodologique adéquat pour caractériser le niveau de concurrence dans l’industrie des télécommunications, plus particulièrement du marché des services résidentiels locaux, et, d’autre part, de proposer des changements (importants) au cadre réglementaire actuel. Je montre que le cadre réglementaire actuel peut engendrer des problèmes importants pour les consommateurs et l’industrie ainsi que des pertes d’efficacité pour l’économie canadienne. Il existe un besoin urgent de réformer le cadre réglementaire actuel, en mettant l’accent sur trois rôles essentiels de l’agence de régulation des télécommunications comme fournisseur d’informations aux consommateurs, comme gestionnaire des conditions de concurrence loyale pour toutes les entreprises et comme promoteur de programmes d’investissement efficaces.competition, regulatory reform, telecommunications , concurrence, réforme de la réglementation, télécommunication
