The lack of knowledge of how resilience management supports enterprise system (ES) projects accounts for the failure of firms to leverage their investments in costly ES implementations. Using a structured-pragmatic-situational (SPS) case study research approach, this paper reports on an investigation into the resilience management of a large utility company as it implemented an ES upgrade. Drawing on the literature and on the case study findings, we developed a process-based resilience management framework that involves three strategies (developing situation awareness, demystifying threats, and executing restoration plans) and four organisational capabilities that transform resilience management concepts into practices. We identified the crucial phases of ES upgrade implementation and developed indicators for how different strategies and capabilities of resilience management can assist managers at different stages of an ES upgrade. This research advances the state of existing knowledge by providing specific and verifiable propositions for attaining a state of resilience, the knowledge being grounded in the empirical reality of a case study. Moreover, the framework offers ES practitioners a roadmap to better identify appropriate responses and levels of preparedness.  相似文献

文章以对12个省/市的378位"老字号"企业管理人员的问卷调查资料为基础数据,描述和分析了"老字号"的经营现状(如竞争优势、存在的不足、最需改进的方面)和发展前景,认为在新一轮的激烈市场竞争中,"老字号"企业不但需要不断适应外部市场变化的全球化和本土化的双重压力,而且需要在企业内部将传统的与现代的两种优势相结合,将已有的与新生的两种竞争力相结合(简称"双结合"),以便具备核心能力。这种"双结合"的核心能力不仅可以使"老字号"企业拥有一定的竞争优势,而且可以让其优化企业价值链管理,持续增强企业市场竞争力。  相似文献

This study expands relationship management theory by testing the linkages between perceived relational quality, organizational impression, and attitude in affecting the behavioral intention of customer public of five major banks. A survey of 1,178 banking customers showed that perceived relational quality, organizational impression, and individual attitude, significantly affected supportive behaviors. Organizational impression was found to be almost three times more determinant than perceived relational quality in affecting individuals' attitudes, and subsequently, their supportive behaviors. By highlighting the role of organizational impression, linkages between the relationship management perspective and other theoretical frameworks, such as image repair, become apparent; bearing implications for scholarship and practice.  相似文献

This study explores Australian small-scale rural lifestyle landowners’ perceptions of and experiences with natural resource management (NRM) extension and incentive programmes and discusses means to better-match such programmes to these landowners’ NRM interests, assistance needs and delivery preferences. Data was collected from seventeen in-depth qualitative case-studies of small-acreage landholders located in the Noosa hinterland in south-east Queensland. These landholders indicated a high need for expert advice, labour and other resource assistance to achieve their property management objectives. They had, however, a low-level of awareness and understanding of available programmes (particularly incentive schemes) that could provide some of their needed support. Other key barriers to the landholders’ participation in these programmes were aversions to support providers, a perceived unsuitability of properties or irrelevance of particular incentive programmes, and concerns about programme application procedures or property-rights and value-related implications of engagement. Increased NRM engagement among small-scale lifestyle landowners may be achievable through amendments to existing support programmes and better communication of these programmes. The design and delivery of appropriate measures and messages may require collaborative partnerships, with knowledgeable and influential ‘go-to’ landowners and peer-mentoring networks playing a critical role. In many cases, conservation-focused incentive programmes may need to facilitate cooperative NRM among groups of adjoining micro-scale lifestyle landowners and allow greater flexibility in the length and allowable land and forest management practices of contractual agreements. Moreover, small-scale lifestyle landowners have much interest in and need for support to integrate multi-purpose agroforestry systems with other environmental and aesthetic property management goals. Workshops, follow-up field-days on participating properties, free one-on-one on-property advice, and NRM guides that include detailed case-study accounts of landowner experiences are important means of communicating the availability, administrative requirements and benefits of support programmes to small-scale lifestyle landowners.  相似文献

Most companies are under pressure to improve the environmental sustainability of their supply chains. However, there is considerable variance in companies' ability to successfully deploy environmental management projects. One important factor, according to articles in the academic and business press, is the ability of champions of sustainable supply chain management (SCM) projects within organizations to gain the commitment of colleagues (e.g., other managers from a variety of functions) to help these projects succeed. Therefore, this paper examines variables that affect a project champion's ability to gain this commitment from colleagues. In particular, building on existing research, this research employs a video‐based experimental design to examine the effect of the influence approach that the project champion employs, the values of the person the champion is trying to influence, and the organizational climate. The results suggest that organizational climate and certain individual values directly affect commitment. There are also interactions between values and influence tactics. The research adds to the field's growing knowledge on the antecedents of sustainable SCM within companies while providing valuable guidance for environmental champions and for top managers.  相似文献

In the 1990s, the Democratic People’s Republic of Korea (North Korea) suffered from severe food shortages and large-scale deforestation, which triggered a stage of rural conservation reform. Since 2004, with support from the Swiss Agency for Development and Cooperation (SDC), North Korea’s Ministry of Land and Environmental Protection (MoLEP) has implemented a Sloping Land Management Program (SLMP). The SLMP established sloping land user groups and granted these groups the right to use marginal land for agroforestry development. This devolution of land rights from state control onto local groups is a landmark in North Korea, and this decentralization initiative has now expanded to over eight counties to involve thousands of households. It has also led to the launch of a National Agroforestry Policy and Strategy. Drawing from both qualitative and quantitative data collected from 2008 to 2014, this paper documents the process and effects of the SLMP. It argues that the decentralization reform in land management has contributed to not only food security with increased food crop diversity and productivity, but also notably forest recovery through an expansion of tree plantations and agroforestry practices on degraded sloping lands. However, an insufficient power transfer in the form of a lack of timber rights granted to the local user groups has hampered the effectiveness of the SLMP. There are also institutional and geopolitical challenges that are limiting further scaling-up of land-use decentralization across the country. The policy implication calls for more international investment as well as national land-use policy reforms in order to promote and facilitate further decentralization of sloping land management and to secure greater use rights for sloping land user groups.  相似文献

This paper investigates volatility spillover in the Nigerian sovereign bond market arising from oil price shocks, using Vector Autoregressive Moving Average ‐ Asymmetric Generalized Autoregressive Conditional Heteroscedasticity (VARMA‐AGARCH) model. The paper covers the period March 22, 2011 to April 14, 2016 and makes use of the daily data of the Nigerian Sovereign Bond, Brent oil and West Texas Intermediate (WTI), respectively. We endogenously and sequentially detect structural break points using the test of Bai and Perron (2003) framework. In order to accurately estimate the model, we modify it by incorporating the break points into the VARMA‐AGARCH model, a process which if ignored would lead to model misspecification. The results obtained demonstrate a significant cross‐market volatility transmission between oil and sovereign bond market with ample sensitivity to structural breaks. The study also computes optimum weight portfolio and hedge ratio both with and without structural breaks and results equally indicate sensitivity to structural breaks.  相似文献
