1、 外文文献：project portfolio management theres more to it thanwhat management enactsabstractalthough companies manage project portfolios concordantly with project portfolio theory, they may experience problems in the form of delayed projects, resource struggles, stress, and a lack of overview. based on a

2、 research project compromised of 128 in-depth interviews in 30 companies, we propose that a key reason why companies do not do well in relation to project portfolio management (ppm) is that ppm often only covers a subset of on-going projects, while projects that are not subject to ppm tie up resourc

3、es that initially were dedicated to ppm projects. we address and discuss the dilemma of wanting to include all projects in ppm, and aiming at keeping the resource and cognitive burden of doing ppm at a reasonable level.keywords： managing programmes， managing projects，organisation resources， strategy

4、1. introductionat any given point in time, most companies engage in many projects. some of these projects may relate to product development and marketing, others relate to changes in work processes and production flows, while yet others relate to competency development, strategic turns, the implemen

5、tation of new it systems, environmental issues etc. a key managerial task is to dedicate resources across all of these projects (as well as do daily work) and consequently,management across projects (project portfolio management (ppm) is critical to company performance.this paper is based on a large

6、-scale qualitative study,which shows that many project-oriented companies do not perform well when it comes to ppm. this relates to the inability to accomplish projects that are initiated. in particular, we identify the following problems: (1) projects are not completed according to plan (or they ev

7、en peter out during their project life cycle);(2) management and employees feel they lack a broad overview of on-going projects (especially when the number of on-going projects increases as more and more projects are not completed according to plan); (3) people experience stress as resources are con

8、tinuously reallocated across projects in order to make ends meet. these observations are especially interesting because the companies were included in the research project because they were supposed to be especially,experienced in ppm, and because they actually engage in ppm according to the extant

9、body of literature on ppm. for example, part of the companies ppm included an effort to pick the best projects on the basis of explicit or implicit criteria, and an effort to allocate sufficient resources to these projects. however, despite efforts,to practice good ppm, these companies experience se

10、vere problems in relation to ppm especially in letting enough resources go into the right projects. the purpose of this paper is to confront ppm as advocated by normative theories with actual ppm practices. hence, the purpose is to confront ppm theories with ppm as perceived by managers and other em

11、ployees for whom ppm is part of, or affects, their work conditions. however, in this paper, we are more interested in ppm as enacted by companies than in universally true perceptions. hence, we adhere to weicks 13 notion of enactment as the preconceptions that are used to set aside a portion of the

12、field of experience for further attention. in regard to ppm, enacted projects are thus the ones management sets aside for further attention (i.e. ppm). as such, we focus especially on ways actors define or enact projects 4 and make sense of how to manage the sum of the projects. drawing on this pers

13、pective, we account for findings that suggest why companies that do engage in ppm still experience problems.2. project portfolio theorythis paper draws on archer and ghasemzadehs 5, p.208 definition of project portfolios as a group of projects that are carried out under the sponsorship and/or manage

14、ment of a particular organization. henceforth, we define ppm as the managerial activities that relate to (1) the initial screening, selection and prioritisation of project proposals,(2) the concurrent reprioritisation of projects in the portfolio,(3) the allocation and reallocation of resources to p

15、rojects according to priority. for quite some time researchers have suggested that low completion rates for new product development (npd) projects and new product failure relate to resource deficiencies in key areas 6,7. furthermore, while a host of researchers 810 have focused on the dimension of p

16、pm that concerns processes relating to selection of projects to be included in the portfolio, research e.g. 11 also increasingly focuses on the day-today management of the project portfolio.3. methodologyover a period of two years, we did empirical research on how companies manage their entire range

17、 of projects, e.g. renewal projects, strategic projects, it projects, departmentally specific projects, and production based projects. in relation to the selection of companies to be included in the empirical study, a key criterion was that the study should cover a wide variety of industries. as a r

18、esult, the empirical study covers 30 companies from industries as diverse as, e.g. mobile telephone communications, finances, energy, pharmaceuticals, toys, software, and foods. however, due to the fact that we were looking for companies, where the amount of on-going projects suggested they were eng

19、aged in ppm, the study is biased towards larger companies as well as companies that define at least a substantial part of their activities as projects. the degree to which the companies participated in the study varies. hence, half of the companies are labelled inner circle companies due to the fact

20、 that we drew extensively on these 15 companies. for example, in these companies more interviews were conducted at various points in time and at various organizational levels. hence, a longitudinal perspective characterizes the involvement of these companies. the remaining half of the companies are

21、labelled outer circle companies because their participation in the study has included fewer top-management interviews, the purpose of which was to gain insight into ways in which (top) management defines the content of their project portfolios and manages them.4. managerial implicationsa key finding

22、 is that the gap between required and available resources is very much attributable to the existence of a host of smaller projects that never become part of enacted project portfolios. thus, at an aggregated level, the empirical study suggests smaller, un-enacted projects qualify as resources crunch

23、ers in so far they are not considered to be a part of enacted project portfolios. in order to overcome this crunch in resources, two solutions seem obvious:(1) enacting more, i.e. having ppm embrace all projects.(2) allocating more resources to a pool of loosely-controlled resources for the un-enact

24、ed projects to draw on.5. research implicationsthe empirical study elaborates on the significant shortage of resources devoted to npd that cooper and edgett argue is the fundamental problem that plagues most firms product development efforts. our work especially suggests that the shortage of resourc

25、es devoted to enacted projects is not a problem that primarily arises in relation to top managements ppm. on the contrary, in-good-faith top management dedicates resources to enacted projects on the basis of sound ppm. however, what top managers do not do is take into account the host of smaller pro

26、jects that individuals initiate and more importantly top managers ignore (or at least heavily under-estimate) the amount of resources that these smaller projects tie up. hence, we argue that especially the crunch in resources may be attributable to the un-enacted competition for resources that small

27、er projects subject enacted projects to. consequently, the key contribution of our empirical work to research is that it emphasises that if we wish to study ppm (and especially if we wish to relate ppm to project performance), we might be better off taking into account the entire range of projects t

28、hat actual (not enacted) portfolios are comprised of. thus, if we as researchers only enact the projects that are neatly listed by top management, then our research will neglect the host of projects that are not subject to ppm, projects that nonetheless take up valuable, and scarce, resources. the f

29、act that the empirical study includes interviews with managers, i.e. those who do ppm, and interviews with personnel at lower organisational levels, i.e. those whose work is subject to ppm, is the reason why we were able to identify un-enacted projects. thus, researchers interested in ppm should be

30、careful not to rely too heavily on a management perspective.6. conclusion and limitationsthe main conclusion is that as long as some projects are un-enacted, companies may experience a drain on resources that reduces the time and resources actually devoted to projects subject to ppm. hence, each ind

31、ividual company should decide whether or not all projects should be part of ppm and if the end result of such a decision is not to make comprehensive project lists (i.e. lists that include all minor projects), then management should decide how many resources should be set aside for the plethora of s

32、mall projects that do not appear on the project list. one way in which the crunch in resources can be reduced is by ensuring that smaller projects do not take up a critical portion of the resources that are officially set aside for the completion of projects subject to ppm. however, due to the explo

33、ratory nature of the study accounted for in this paper, our findings relate far more to what companies actually do (positive theory in hunts terms), rather than to what they ought to do (normative theory in hunts terms). although generating positive theory is indeed a crucial first step especially i

34、n relation to the future of ppm theory positive theory cannot, and should not, stand alone. hence, the key challenges for ppm theory in the future are to produce normative theory that offers sound suggestions as to how companies can improve their ppm. another limitation of our study is that the empi

35、rical part was carried out in a danish context as the 30 companies involved are located in denmark, which may not be sufficiently representative for companies worldwide because denmark has, to a larger extent, a bottom-up culture. therefore, the portion of smaller un-enacted projects may be bigger h

44、问题，特别是让充足的资源进入到“最佳的”工程。本文通过ppm相关的理论基础并且结合ppm的实践来解决ppm中遇到的问题。由此为ppm影响一些经理或者工作条件的员工用ppm理论解决一些问题。然而，在本文，我们对ppm更感兴趣，由于他们是由公司制定出来的而不是普遍性的感知。因此，我们遵守制定的weicks 13概念作为预想，用于留出经验的领域的部分引起注意。 关于ppm而制定的项目受到近一步关注。同样地，我们特别集中于演示方式或者制定工程，并且使如何管理工程总数变得有意义。 从这个角度来讲，我们想找到并提议为什么有些公司致力于ppm仍然会遇到问题。2.项目组合理论本文引用archer 和ghase

45、mzadeh的关于项目组合的定义“一组在赞助和或者由一个特殊组织进行管理的项目”由此，我们把ppm 作为管理活动而定义为和以下方面相关：（1）最初的筛选，挑选，项目小结报告的优先权， （2）在组合中同时存在的优先权（3）根据优先权对项目的资源分派和再分配。相当一段时间内调查者发现新产品的开发项目的低成功率和新产品的失败主要是由于在关键领域资源缺乏。此外，许多研究员聚焦了在组合调查中包含的项目过程,并且提升对每天的工程项目的管理进行关注。3.方法论在两年内，我们做了实证研究,关于公司处理他们的项目的整个范围，即更新工程，策略工程，it工程，部门特色工程和以生产为基础的工程。在实地研究中挑选的公司

46、中，一个主要的标准就是这项研究必须覆盖各种各样的产业。这样一来，这项研究覆盖了各行业的30家公司。即包括移动通信，财务，能源，制药，玩具，软件和食品。然而，基于我们寻找公司的事实，有相当数量的正在进行项目表明他们在从事ppm.此项研究偏向于更大的并且把他们相当一部分的活动至少定义为工程的公司。参与此项研究的公司的规模大小不一。因此，我们广泛地挑出15家公司，这些公司被标记为“核心”公司。例如，这些公司将会及时的在不同的时刻和不同的组织水平接受到更多的采访。由此，从纵向角度描绘这些介入的公司。剩余的一半公司被标记为“外圈”公司，因为他们在此项研究中参与很少的高层次管理访谈。这么做的目的是对高层次

47、管理定义他们的工程组合的内容以及如何管理增强洞察力。4. 管理涵义关键的发现是，必须和可利用的资源之间的空隙大大助长了众多本不属于工程投资管理的小项目的存在。因此，在广泛意义上，实证研究建议，更小的未被执行的工程在资源摩擦中取得资格，因此，它们并不被认为是工程投资管理的一部分。为了克服这种资源的摩擦，两种解答似乎很明显： （1）制定更多，即使工程项目投资包含所有项目。 （2）增拨资源给控制松散的资源库，以利用未被执行的项目。5. 研究涵义实证研究阐述了“重要资源用于新产品开发”的库伯和埃奇特21认为最根本的问题是困扰大多数企业短缺产品的开发力度。我们的工作尤其表明，致力于工程项目投资的资源短缺

48、并不是与高级管理的ppm相关联的问题。相反，善意的高级管理致力于以良好的ppm为基础的资源以制定项目。然而，高级管理者并未考虑到企业正在执行的众多小项目，更重要的是，高层管理者忽视了（或者说低估了）这些小项目所耗费的资源量。 因此，我们认为，特别是在资源危机时期，可能是联合国指定的对资源的竞争使规模较小的项目受到限制。因此，我们实证研究的主要贡献是，它强调，如果我们想研究ppm（尤其是我们想将ppm和项目执行结合起来），我们可能会更好地考虑到实际（不通过）组成的投资组合项目的整个范围。因此，如果作为研究者的我们只是制定由高层主管列的清单，我们的研究就会忽略众多不属于ppm的项目，尽管这些项目如

49、此占用宝贵的稀缺的资源。实证研究，包括与经理面谈，即那些做ppm的人，包括在较低的水平与工作人员组织的面试，即他们的工作是受ppm制约的，这一事实就是为什么我们能够确定联合国制定的项目。因此，对ppm的感兴趣的研究人员应该小心，不要过分依赖于一个管理的角度。6.结论和局限主要结论是，只要是有些项目未被施行，公司就面临着资源流失的危险，而这些资源正是公司致力于减少时间和物力财力而实施的项目组合管理所需要的。因此，每一个公司都应该判断出所有项目是否应该隶属于项目组合管理，如果这样决定最终的结果不做全面的项目的列表（即包括所有大小项目的名单）的话，管理者就应该决定留出多少资源放在那些不在列表之上的过多的小项目上。可以降低资源摩擦的一种方式是保证小项目不会过多的占用为完成项目组合管理而实施的项目的资源。然而，在本篇论文中，由于研究的探索性质，我们的研究结果更多地关注于公司实际上做了什么（hunt的正面理论第23期），而非他们应该做什么（hunt 的基准理论23期），尽管产生正面理论确实是关键的第一步尤其是有关于与项目组合管理理论的未来正面理论不能也不应该单独成立。因此，项目管理理论未来的主要挑战就是产生
