滑坡灾害治理方案的优劣直接影响到工程造价的高低、实施效果的好坏,但方案选择是一个复杂的系统过程,目前这类项目决策实践中采用的方法均存在一定的主观随意性。价值工程是国际上通行的一种项目决策分析方法,在产品设计、项目决策等诸多领域都得到了广泛应用,但尚未有在滑坡治理方案比选方面的应用。本文在回顾总结价值工程原理、分析滑坡治理工程特殊性的基础上,指出滑坡各治理方案的功能可视为固定,从而可将价值工程简化为寿命周期成本分析,据此提出了运用寿命周期成本分析进行滑坡治理方案的基本思路和步骤。实例研究表明,这一方法不仅较传统方法客观可靠,而且评价过程简便明了,对类似项目决策具有一定的借鉴意义。  相似文献

Project motivation is a key aspect to a successful project, yet few studies exist that shed light on this important subject. This article reviews the current literature and theoretical aspects of motivation and provides an analysis of the data. A survey was conducted by soliciting project managers to tell how they perceive their ability to influence motivation. In total, 115 certified project managers responded to the survey. A discussion and suggestions for future research follow the data.  相似文献

Strategic project management is gradually becoming a popular and growing trend within the discipline of project management. The general idea is that project management teams must learn how to deal with the business aspects of their projects, as well as better support their company's business strategy and sustainability, rather than just focus on meeting traditional time, budget, and performance goals. Although this approach has been gaining popularity, strategic project management has not yet become an explicit and widely used approach in the practice of project implementation. One of the concepts mentioned as an important element is project strategy; however, no universal framework or even a clear definition of what project strategy is has so far emerged. The goal of this article is to fill in this gap and provide a useful definition and a framework for the further study and implementation of the project strategy concept. Specifically, to achieve this goal, we first look at the origins of strategy in military and business research to discuss the question of what, exactly, project strategy is; we follow this discussion with an explicit definition of a project strategy. We then outline a framework for building a dedicated project strategy document for an individual project, and show how this framework can guide the project planning and execution processes. Using a case study approach, which included an action research phase, we demonstrate how project teams can adopt the strategy concept in a natural way that would lead their project to better business results.  相似文献

根据项目融资中对项目的所有权分配情况,文章认为在项目的投资结构设计中存在4种不同类型的融资契约,分别是权益型融资契约、负债型融资契约、要素型融资契约和信用保证型融资契约。在项目以未来现金流作为收益来源的前提下,上述的4种融资契约通过各投资主体的不同资本注入形式,参与收益的分配。  相似文献

This study investigates whether project management maturity (PMM) relates to perceived organizational performance and how an organization's cultural orientation is a contributing factor. Perceived organizational performance is defined as project effectiveness and efficiency followed by resulting business performance. A survey‐based research was conducted with 86 project professionals from various U.S. service and manufacturing organizations. The study revealed that PMM is significantly related to business performance but not to project performance. Furthermore, while clan organizational culture is a sole contributing factor for project and business performances, PMM interacts with market culture in improving business performance. This study shows that in order to deal with project time, budget, and expectations issues, an organizational culture change toward sharing, collaboration, and empowerment is a must. Furthermore, an increasing project management maturity along with a results‐oriented organizational culture improves an organization's competitiveness, resulting in cost savings and increased sales. PMM efforts are therefore crucial. PMM accompanied by an understanding of cultural orientation is a best strategy for today's project‐based organizations.  相似文献

Technology assumes importance in the context of project management due to greater challenges in today's technology‐enabled work environment, where technology tools are routinely used for collaboration, communication, and deployment of project management practices. It is becoming common practice for even co‐located project teams to use the electronic medium for these purposes. Notwithstanding the importance of technology, research has shown that it is difficult to associate the use of technology with business performance and the absence of such relation can be extrapolated to project performance as well. However, technology can play a major role in supporting project managers in managing projects effectively and efficiently. Several studies have addressed the importance and leadership style of project managers. However, specific roles and responsibilities of a project manager toward the project team is an area that needs further study. In this research effort, using the literature review, important people‐related factors of project performance are identified. Then structured personal interviews were used to gather data for understanding relations among these factors in order to develop a project manager performance model. The model was developed employing the interpretive structural modeling (ISM) methodology. The model was used to determine the role of the project manager in managing the project team and improving the project performance. Results show that both leadership and management roles are important. This study helped to analyze underlying interactions among these factors and, consequently, understand the supportive function of technology to the project manager in improving project performance.  相似文献

Based on a business‐to‐business (B‐to‐B) case within the automotive industry, this study proposes logics (constructivist and determinist, respectively) of protagonists and highlights the complexity of their dynamics during the successive project's phases. The concept of milieu will emphasize the complex business in which project marketing takes place; notably, it allows better identification of relevant relationships. Our article focuses on this concept of milieu with regard to the interactions between project marketing and project management actors during project phases. In particular, this article underlines the difference and the accommodation between the dynamics of interaction and the dynamics of congruence of marketing and management logics.  相似文献
