    Increasingly, enterprises are using Service-Oriented Architecture (SOA) as an approach to Enterprise Application Integration (EAI). SOA has the potential to bridge the gap between business and technology and to improve the reuse of existing applications and the interoperability with new ones. In addition to service architecture descriptions, architecture abstractions like patterns and styles capture design knowledge and allow the reuse of successfully applied designs, thus improving the quality of software. Knowledge gained from integration projects can be captured to build a repository of semantically enriched, experience-based solutions. Business patterns identify the interaction and structure between users, business processes, and data. Specific integration and composition patterns at a more technical level address enterprise application integration and capture reliable architecture solutions. We use an ontology-based approach to capture architecture and process patterns. Ontology techniques for pattern definition, extension and composition are developed and their applicability in business process-driven application integration is demonstrated

    Business objects: the next step in component technology?

    Get PDF
    Component technology seems to be a promising approach towards more efficient software development by enabling application construction through “plug and play”. However, the middleware supporting this approach is still complicated to use and distracts the attention of the component developer from the application domain to technical implementation issues. Business objects are intended to hide the complexities of middleware approaches and provide an easy to use environment for application developers. We conceptualize business object approaches by presenting a common model and survey some major players in the marketplace. We conclude by identifying implications of business objects on information systems engineering.

    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

    Modelling electronic service systems using UML

    This paper presents a profile for modelling systems of electronic services using UML. Electronic services encapsulate business services, an organisational unit focused on delivering benefit to a consumer, to enhance communication, coordination and information management. Our profile is based on a formal, workflow-oriented description of electronic services that is abstracted from particular implementation technologies. Resulting models provide the basis for a formal analysis to verify behavioural properties of services. The models can also relate services to management components, including workflow managers and Electronic Service Management Systems (ESMSs), a novel concept drawn from experience of HP Service Composer and DySCo (Dynamic Service Composer), providing the starting point for integration and implementation tasks. Their UML basis and platform-independent nature is consistent with a Model-Driven Architecture (MDA) development strategy, appropriate to the challenge of developing electronic service systems using heterogeneous technology, and incorporating legacy systems

    A Knowledge Transfer Partnership - the development of a Bespoke Enterprise Resource Planning System in the UK

    Get PDF
    Abstract. A Knowledge Transfer Partnerships (KTP) is a UK-wide programme designed to enable businesses to improve their competitiveness, productivity and performance. A KTP achieves this through the forming of a Partnership between a business and an academic institution. The aim is to enable businesses to access skills and expertise from academics and embed this knowledge in their businesses in order to develop the business. The knowledge sought is embedded into the business through a project, or projects, undertaken by a recently qualified person (known as the Associate). Part funding is provided by the government towards the Associate’s salary and towards the release of an Academic supervisor who works a half a day a week at the company. KTPs can vary in length from 6 months to three years, depending on the needs of the business and the desired outcomes. Therefore a KTP enables new capability to be embedded into the business and has benefited and continues to benefit a wide range of businesses across many sectors in the UK, including micro sized, small and large businesses across many sectors. This paper describes a Knowledge Transfer Partnership project between the University of Hertfordshire and a small and medium sized enterprise (SME) based in Cambridgeshire, UK.Final Accepted Versio

    The Design and Implementation of a bespoke Enterprise Resource Planning System (ERP) for an acoustical engineering company

    This paper will describe the tasks completed so far as part of a Knowledge Transfer Partnership between the University of Hertfordshire and Acoustical Control Engineers (ACE) a ‘small and medium sized enterprise’ (SME) based in Cambridgeshire, UK. ACE’s 25 personnel design, manufacture and install noise and vibration control systems to solve a wide range of acoustic problems. The projects undertaken include acoustic enclosures for supermarket refrigeration plant and for generators used in many situations, together with other more diverse applications such as controlling noise in the workplace and even on a luxury boat. Before the current KTP project the company used some partially computerised systems consisting of spreadsheets to perform acoustic analyses, pricing and project management functions supplemented with a paper based system to ‘fill the gaps’. Enterprise Resource Planning (ERP) systems provide an integrated database for all parts of the organisation allowing decisions to be based on a complete understanding of the organisation’s information, avoiding the problems due to duplication of data and ensuring that the consequences of decisions in one part of the organisation are reflected in the planning and control systems of the rest of the organisation. ERP systems became popular from the 1990’s mainly in relatively large organisations due to the complexity and cost of these systems. This project is unusual in that rather than adapting an off-the-shelf ERP solution to ACE’s very specific and specialised requirements we are taking an ERP development approach in an SME whose legacy systems are made up of spreadsheet and paper based systems. For the software development an Agile approach has been used. Agile involves software development methods based on iterative and incremental development. The initial attempt was to start developing the ERP from an Open Source ERP Source Code; however this effort was futile as a result of the bespoke nature of ACE’s business and product lines. Mapping ACE’s data model to the database which any existing ERP system could be adapted to, proved to be a very difficult problem. Therefore, developing the ERP from first principles was inevitable. Several of the ERP modules have been developed, user training has taken place and the core modules have been signed off. The project is due to complete in September 2014 and by this time we will have further information on how the ERP system has increased the competitiveness of the company, as well as experience of introducing an ERP into an SME. However, as would be expected the work undertaken developing the system so far has had several significant effects on ACE and acted as a catalyst for change in various parts of ACE’s business.Non peer reviewe

    Multi-Stakeholder Assessment of Critical Success Factors: Insights from the World's Fastest SAP R/3 Implementation

    Get PDF
    Organizations invest substantial resources in Enterprise Systems (ES) expecting positive outcomes for the organization and its functions. Implementing an ES is a lengthy and costly undertaking, with general upheaval for many of the organizations. Many organizations therefore are seriously considering rapid ES-implementations to reduce cost and other related resources. This paper presents findings of a study conducted to understand critical success factors of rapid ES-implementations gathering data from the world’s fastest SAP implementation, completed in a record time of three weeks. Using a two-phased case study design, gathering data from four distinct stakeholders, this study recognized the relevance of critical success factors identified through the literature to the context of rapid ES-implementations. Moreover, the study identified three new critical success factors that are specific to rapid ES-implementations. The study also demonstrated differentiating views of multiple stakeholders on each of the critical success factors
