Abstract

This article investigates the development and application of key performance indicators for global product development. Two in-depth, longitudinal case studies with multinational Danish manufacturing companies were conducted, and highlight how key performance indicators, typically used for collocated, cross-functional product development, do not provide the predictive insight required to avoid the additional risks encountered in the global product development environment. Grounded in the case study results and building on established methodologies in performance measurement literature, a framework was developed and validated in two additional Danish companies to support project managers to develop: preventive indicators, which support the avoidance of identified risks, and outcome indicators, which support the measurement towards the attainment of project objectives. The study is unique as it is one of the very few longitudinal studies of engineering design activities in a global context, providing the in-depth contextual understanding towards key risks and their influence on performance; an important step to support researchers and practitioners with the development of preventive measures.  相似文献

The purpose of this research was to determine what behaviourally distinguishes effective and ineffective managers within a Moroccan Higher Education Institution (HEI). The critical incident technique (CIT) was the methodology deployed to collect data from participants in terms of how they perceive managers as either effective or ineffective. The collected data (CIs) were subjected to content and thematic analysis that resulted in derived positive and negative behavioural statements (BSs). A total of 42 participants/informants were interviewed and revealed a total of 418 CIs, of which 189 were positive CIs and 229 were negative. The analysis revealed a total of 49 BSs, of which 19 were positive and 30 were negative behavioural indicators. The findings of this investigation bring empirical evidence to understand what and how managers are perceived as effective or ineffective in the Moroccan academic context and, therefore, adds to the literature. The information obtained can also provide rich information/knowledge that can be used as a basis to address the behavioural developmental needs of managers in HEIs. This research adds value by following by following two previous replication studies in a French and a Hungarian HEI; moreover, this study is the first to be conducted in the Moroccan/North African region.  相似文献

Despite its connotations of non‐compliance, illegality, social exploitation and marginality, the informal sector is a substantial contributor to economic life in developing countries and, increasingly, in more technologically advanced activities. Its prevalence in developed economies has also become more widely recognized. In light of its significance, this paper reviews research on the informal sector from a management and organization scholarship perspective, rather than from an entrepreneurship view, as has been the focus until now. It sets out the atypical management practices that are inherent in the sector, explores the under‐researched relationship between formal and informal firms, and highlights definitional, conceptual and other limitations in extant research. As a step in resolving these issues, the authors present a conceptual model of formality and informality in a three‐dimensional framework that highlights an organizational infrastructure dimension, a view of firms operating along a continuum, and a multi‐level analytical context. Building on this, the authors detail opportunities for enhanced appreciation of in situ management and organizational practices in the informal sector and outline tools for pursuing a management and organization scholarship agenda. Overall, the authors argue that management scholarship has great potential to improve understanding of the informal sector, and that the informal sector provides opportunities to advance management theory, research and practice.  相似文献

A simple connected graph G with 2n vertices is said to be k-extendable for an integer k with \(0<k<n\) if G contains a perfect matching and every matching of cardinality k in G is a subset of some perfect matching. Lakhal and Litzler (Inf Process Lett 65(1):11–16, 1998) discovered a polynomial algorithm that decides whether a bipartite graph is k-extendable. For general graphs, however, it has been an open problem whether there exists a polynomial algorithm. The new result presented in this paper is that the extendability problem is co-NP-complete.  相似文献

Network coding is a generalization of conventional routing methods that allows a network node to code information flows before forwarding them. While it has been theoretically proved that network coding can achieve maximum network throughput, theoretical results usually do not consider the stochastic nature in information processing and transmission, especially when the capacity of each arc becomes stochastic due to failure, attacks, or maintenance. Hence, the reliability measurement of network coding becomes an important issue to evaluate the performance of the network under various system settings. In this paper, we present analytical expressions to measure the reliability of multicast communications in coded networks, where network coding is most promising. We define the probability that a multicast rate can be transmitted through a coded packet network under a total transmission cost constraint as the reliability metric. To do this, we first introduce an exact mathematical formulation to construct multicast connections over coded packet networks under a limited transmission cost. We then propose an algorithm based on minimal paths to calculate the reliability measurement of multicast connections and analyze the complexity of the algorithm. Our results show that the reliability of multicast routing with network coding improved significantly compared to the case of multicast routing without network coding.  相似文献

Over the last fifteen years companies tended to formalise their innovation management activities and to establish formal jobs like the innovation officer, the network manager or the innovation manager. Knowledge of the informal role profiles of these formal roles is still rare. HR and R&D Managers do not know which informal role profile might suit them best, thus having difficulties to assign the best candidates for jobs in innovation management. Researchers cannot help to resolve the problem. Our research answers the question what innovation managers really do, by analysing their tasks, skills and traits, theoretically based on informal role theories. Furthermore, we will analyse how these characteristics change with company size. To provide answers to our research questions we choose a multiple-case study approach. We found, among others, that innovation managers fulfil the role of the relationship and process promotor or a combination of both with the champion, but we also found, that the innovation manager’s roles profile becomes fuzzier with shrinking company size. Our results have practical implications for top management and also HR and R&D managers, enabling them to better select and steer employees in innovation management. Researchers will be able to build on our results because we offer a comprehensive understanding of the informal role profiles of innovation managers based on informal role theories.  相似文献

In recent years, the Dutch healthcare sector has been confronted with increased competition. Not only are financial resources scarce, Dutch hospitals also need to compete with other hospitals in the same geographic area to attract and retain talented employees due to considerable labour shortages. However, four hospitals operating in the same region are cooperating to cope with these shortages by developing a joint Talent Management Pool. ‘Coopetiton’ is a concept used for simultaneous cooperation and competition. In this paper, a case study is performed in order to enhance our understanding of coopetition. Among other things, the findings suggest that perceptions of organizational actors on competition differ and might hinder cooperative innovation with competitors, while perceived shared problems and resource constraints stimulate coopetition. We reflect on the current coopetition literature in light of the research findings, which have implications for future research on this topic.  相似文献

Despite a long history within the field of leadership, the subject of authoritarianism and how it influences leadership and leadership processes has been neglected in recent decades. However, recent global events make it clear that a better understanding of authoritarianism is needed and that leadership researchers would benefit from a renewed interest in studying why followers embrace autocratic leaders. The nature of authoritarian character, how authoritarian values develop, and how it is measured will be discussed. We will also review autocratic leadership, the factors that make it more likely, its consequences for followers, and the moderators of its effects. A future research agenda for the study of authoritarian character and autocratic leadership will be provided.  相似文献

The purpose of our research is to examine the relationship between subordinate ratings of a target-leader's empathic emotion and boss ratings of performance of that target-leader. Furthermore, using hierarchical linear modeling, we assess whether the cultural background of the target-leader moderates this relationship. Our results show that leaders who are rated by their subordinates as engaging in behaviors that signal empathic emotion are perceived as better performers by their bosses. In addition, we found that the GLOBE societal culture dimension of power distance was a significant cross-level moderator of the relationship between empathic emotion and performance. Implications for leading in cross-cultural and multicultural contexts are discussed.  相似文献

The leader–member exchange (LMX) theory of leadership focuses on the quality of relationships built between leaders and subordinates; LMX measures are designed to assess the quality of these relationships. Since the leader and subordinate are jointly embedded in the relationship, it is reasonable to assume that their ratings of their relationship will converge to some reasonable extent. However, leader–member convergence on the most widely used measures, the LMX-7 and SLMX-7 scales, has historically been low. To address this, we conduct two studies to investigate whether item wording and content might be a cause of poor LMX convergence. The obtained results support the conclusion that the wording and content of these measures are, in fact, introducing attributional and social desirability biases into the rating process and causing some of the poor LMX convergence that is commonly seen. Implications for extant and future LMX research are discussed.  相似文献
