工程项目的一次性决定了工程项目部的一次性,而工程项目成本中心与企业利润中心地位又辱致工程项目部的临时性,在工程项目实践过程中,项目经理部的一次性在实现其功能的过程中可能会产生很多局限和负面影响,故项目部应具有相对的稳定性,在此基础上,本对工程项目部建设实践进行了初步总结并提出了建议。 相似文献

Contemporary imaginations of the impact of new digital technologies (NDTS) are dominated by utopian visions of a ‘revolution’ in productivity and efficiency, contrasted with dystopian views of declines of work and human skills, and distrust of artificial intelligence's efficacy. This article explores imaginations of digital futures in the infrastructure sector through case study research of a global engineering organisation. Drawing on a practice approach, a typology is generated from interviews with engineers and managers to reveal that three broad imaginations compete within the organisation: technodeterminism; technoscepticism; and human-centric, all with utopian and dystopian variants. Clear relationships exist between the diverse imaginary positions taken by employees with their different roles, biographies and levels of the organisational agency. Those with relatively higher levels of agency tended towards technocentric utopianism while those with lower levels of agency displayed a resolutely dystopian version. Conversely, while the outward-facing image of the organisation promotes a utopian imagination of a technologically driven future, those with the very highest levels of the organisational agency remain technosceptic. This means that real change is slow. However, an encouraging manifesto for the future is suggested by those who are innovating NDTS to reimagine alternative infrastructure futures through improved human-centric social outcomes. 相似文献

The issue of spaces for non-organised employee resistance has attracted renewed attention due to the diffusion of new digital technologies in the workplace. The ability of new technologies to measure and restrict employee behaviour in new ways requires explanations of resistance that account for both technology’s material characteristics and employee agency, without descending into technological determinism. This article is based on a case of effective resistance to a new data reporting technology introduced in home nursing in Denmark and explores the causes, forms and outcomes of the resistance. In this study, labour process theory is complemented with Edwards and Ramirez’s classification of dimensions of technological change. The study argues that two dimensions are important for effective employee resistance to technology: contestation of the unintended rather than the intended effects of the technology and the non-immanence of the effects in the technology, which allows the employees to reconstitute it in use. 相似文献

A considerable part of firms' marketing services are supplied by external providers, e.g. advertisement agencies, printing houses, trade fair exhibition builders. Although a large spend category, low involvement of purchasing departments prevails during the procurement decision process. This paper develops a conceptual model of purchasing departments' involvement in marketing service procurement along the dimensions “breadth along process” and “depth of integration”, thus contributing to the measurement of purchasing departments' involvement. Drawing on the findings of a case study, we further propose that the impact of purchasing departments' involvement on procurement success is moderated by procurement complexity, and the duration of the relationship between the purchasing and marketing employees. In addition, barriers to purchasing departments' involvement are conceptualized as lack of skills, lack of motivation, and lack of opportunity. 相似文献
