    Cost-benefit modelling for reliability growth

    Decisions during the reliability growth development process of engineering equipment involve trade-offs between cost and risk. However slight, there exists a chance an item of equipment will not function as planned during its specified life. Consequently the producer can incur a financial penalty. To date, reliability growth research has focussed on the development of models to estimate the rate of failure from test data. Such models are used to support decisions about the effectiveness of options to improve reliability. The extension of reliability growth models to incorporate financial costs associated with 'unreliability' is much neglected. In this paper, we extend a Bayesian reliability growth model to include cost analysis. The rationale of the stochastic process underpinning the growth model and the cost structures are described. The ways in which this model can be used to support cost-benefit analysis during product development are discussed and illustrated through a simple case

    Hidden champions - how young and small technology-oriented firms can attain high export-sales ratios

    Determinants of a firm?s export-sales ratio (degree of internationalisation) are frequently discussed in the literature related to individual firms? export activities. Stylised facts show a positive relationship between firm size and firm age on the one hand and the firm?s export-sales ratio on the other hand. However, anecdotic evidence and recent empirical results revealed that it is not size or age per se that leads to a high export-sales ratio. This paper analyses the export-sales ratio of a sample of young technology-oriented firms in Germany and the UK. The empirical results confirm that neither youth nor smallness are necessarily an obstacle to realising a high degree of internationalisation. However, this requires that the firms possess firm-specific assets in order to overcome barriers to entry into the foreign market. These firm-specific assets may be acquired via conducting own R&D activities, buying novel technology from other companies, or by employing internationally experienced managers. --High-technology industries,export-sales ratio,fractional logit model

    Case Studies in Industry: What We Have Learnt

    Full text link
    Case study research has become an important research methodology for exploring phenomena in their natural contexts. Case studies have earned a distinct role in the empirical analysis of software engineering phenomena which are difficult to capture in isolation. Such phenomena often appear in the context of methods and development processes for which it is difficult to run large, controlled experiments as they usually have to reduce the scale in several respects and, hence, are detached from the reality of industrial software development. The other side of the medal is that the realistic socio-economic environments where we conduct case studies -- with real-life cases and realistic conditions -- also pose a plethora of practical challenges to planning and conducting case studies. In this experience report, we discuss such practical challenges and the lessons we learnt in conducting case studies in industry. Our goal is to help especially inexperienced researchers facing their first case studies in industry by increasing their awareness for typical obstacles they might face and practical ways to deal with those obstacles.Comment: Proceedings of the 4th International Workshop on Conducting Empirical Studies in Industry, co-located with ICSE, 201

    Design of an innovation platform for manufacturing SMES

    Get PDF
    This paper reports on the conception of a collaborative, internet-based innovation platform with semantic capabilities, which implements a new methodology for the adoption of a systematic innovation process in globally-acting networked SMEs. The main objective of the innovation platform is to stimulate the generation of ideas, the selection of good ideas and their ultimate implementation. The platform will support SMEs to manage and implement the complex innovation processes arisen in a networked environment, taking into account their internal and external links, by enabling an open multi-agent focused innovation system, facilitating customer, provider, supplier and employee- focused innovation. The solution is specifically focused on the needs of manufacturing SMEs and will observe product, process and management innovation. The paper presents the key elements of the innovation model and makes references to a novel approach concerning the development of a robust and flexible Central Knowledge Repository for the innovation platform

    System implementation: managing project and post project stage - case study in an Indonesian company

    The research reported in this paper aims to get a better\ud understanding of how the implementation process of\ud enterprise systems (ES) can be managed, by studying the\ud process from an organisational perspective. A review of\ud the literature on previous research in ES implementation\ud has been carried out and the state of the art of ES\ud implementation research is defined. Using several body of\ud literature, an organisational view on ES implementation is\ud described, explaining that ES implementation involves\ud challenges from triple domain, namely technological\ud challenge, business process related challenge, and\ud organisational challenge. Based on the defined state of the\ud art and the organisational view on ES implementation\ud developed in this research, a research framework is\ud presented, addressing the project as well as the postproject\ud stage, and a number of essential issues within the\ud stages. System alignment, knowledge acquisition, change\ud mobilisation are the essntial issues to be studied in the\ud project stage while institutionalisation effort and\ud continuous improvement facilitation are to be studied in\ud the post-project stage. Case studies in Indonesian\ud companies are used to explain the framework
