In R&;D organizations of high tech firms, multiple R&;D projects are executed concurrently and timeliness of project completion - i.e., developing the right products at the right times - is a matter of serious concern. Given that the priority of R&;D projects and the interdependencies between the projects in a high tech firm change dynamically, high tech R&;D project management is a complex and challenging endeavor. To improve the understanding and management of high tech R&;D projects, this paper reports the findings of a field study where we, first, develop and empirically estimate a model that relates project priority over time with the generative mechanisms of market pull and technical challenge associated with R&;D projects. Next, we develop and demonstrate the application of a process model within which the time-varying project priority model is embedded. The process model makes it possible to allocate fixed resources among competing projects with time-varying interdependencies, thereby improving the timeliness of project completion. This research was conducted in collaboration with a major U.S. high tech firm. The corporate R&;D center of the firm served as the research setting for the field study. We present an application of the process model to delineate the evolution of the R&;D organization with the merger of its (technology driven) parent firm with another (market driven) high tech manufacturing firm. The application of the process model generates theoretical insights that are used to develop testable propositions. Implications of the study findings and directions for future research are discussed.  相似文献

To heed the recent calls for more inquiries into the endogenous nature of governance decisions, this study aims to develop a comparative perspective on the performance implication of the project interface design in the context of international scientific cooperation. Using Heckman's two-stage model in a sample of 217 international scientific cooperation projects sponsored by the Taiwanese government, this study shows that project performance characterized by the collective knowledge creation is explained more by team competence and inter-team social capital than by the project interface choice per se. Furthermore, the knowledge co-creation performance is impaired in the presence of project interface misfit, either over- or under-guarding the knowledge exchange in science cooperation. The findings not only yield implications for managing international cooperation in scientific research but offer comparability and equivalency with the organization-level studies characterized by knowledge exchange/creation and governance difficulties.  相似文献

Efficient project execution is a key business objective in many domains and particularly so for capital projects in the process industries, but existing project management research gives little direction about how project team factors influence three important capital project outcomes: cost, schedule, and operability. After an extensive cross-disciplinary review of the general team and project management literatures, we constructed and tested a theoretically based, five-dimensional model of organizational context, project team design, project team leadership, project team processes, and project outcome factors. We examined the model by means of an empirical study of 56 newly completed capital projects executed by 15 Fortune 500 companies in the process industries. The results indicate the value of disaggregating project outcomes for research purposes. Different bundles of project team factors were found to drive project cost, schedule, and operability. Project team efficacy, cross-functional project teams, autonomous project team structure, and virtual office usage were the strongest predictors of project cost effectiveness. Continuity of project leadership, cross-functional project teams, and project manager incentives were the strongest predictors of project construction schedule. In contrast, clear project goals and an office design to facilitate effective communication were the main predictors of plant operability. Implications of these findings for researchers and project practitioners are discussed. One major practical implication of our findings is that project managers need to clearly focus and prioritize their goals for each project so they can adopt the appropriate bundles of project team practices that will facilitate their goal achievement.  相似文献

When faced with limited resources, project managers must determine which projects to fund at what levels from a pool of potential ones. This problem of project selection is inherently multiobjective since various factors, such as the available budget, the chance of success, and the efficient allocation of the project team, must be considered simultaneously. The uncertainty of the data at the time decisions are made further complicates project selection. In this paper, a multiobjective, integer-constrained optimization model with competing objectives for project selection is formulated using probability distributions to describe costs. The objectives correspond to important project criteria, such as: rank (value), managerial labor needed, and average cost. The subjective rank is determined via the Analytic Hierarchy Process. The model is applied to a data set from a US government agency that involves 84 separate projects. The results indicate improved budgetary efficiency compared to the actual project selection, thus supporting use of the model for public sector project selection. The model is unique since it integrates multiobjective optimization, Monte Carlo simulation, and the Analytic Hierarchy Process.  相似文献

How do firms decide which R&D projects to pursue and which ones to cast aside? We use a real options approach to advance our understanding of how firms manage uncertainties in R&D project management, in particular uncertainties linked to the external scientific environment. Our findings highlight how these uncertainties have an impact on the initiation and discontinuation of R&D projects. We examine these effects in the context of shifts in US science policy in the cell therapy field, using a dataset on 570 R&D projects in the global cell therapy sector, initiated over the period 1986–2011. We find decreased R&D project initiation rates and higher discontinuation rates for projects initiated by US firms in the aftermath of policy shifts that increased uncertainties about public funding support for US cell therapy research. We also highlight how this effect was reversed as the US public funding outlook for such research recovered.  相似文献

Medical crowdfunding platform helps numerous patients access enthusiastic donors and address financial difficulties, but many crowdfunding projects fail to reach their target amount. Thus, how a crowdfunding project can attract considerable donors is questionable. This study examines the effects of attention and reliability on the performance of online medical crowdfunding projects and how target amount changes such effects. Based on objective data of 1177 crowdfunding projects from 2016 to January 2018 in a large medical crowdfunding platform in China, we find that the project donor’s attention (the number of forwards and comments) and reliability (the number of dynamic updates, empirical users, and pictures) positively affect the medical crowdfunding performance of the projects. However, target amount weakens the positive effects of the number of forwards and comments in online medical crowdfunding projects. Therefore, project sponsors should set reasonable target fundraising amounts while showing attention and reliability to donors. Compared with previous research that mainly explores the influence of external factors on crowdfunding outcomes from the perspective of donors, this paper focuses on the internal project factors and explores the concerns and trustworthiness of crowdfunding projects, enriching the literature related to fundraising ability in the project.  相似文献

This paper presents a new methodology combining multiple criteria sorting or ranking methods with a project portfolio selection procedure. The multicriteria method permits the comparison of projects in terms of their priority based on qualitative and quantitative criteria. Then, a feasible set of projects, i.e. a portfolio, is selected according to the priority defined by the multiple criteria method and satisfying a set of resources and logical constraints. The proposed portfolio selection methodology is called Priority Based Portfolio Selection (PBPS) and can be applied in different contexts. We present an application in the urban planning domain where our approach allows us to select a set of urban projects based on their priority, budgetary constraints, and urban policy requirements. Given the increasing interest of historical cities to reuse their cultural heritage, we applied and tested our methodology in this context. In particular, we show how the methodology can support the prioritization of the interventions on buildings with some historical value in the historic city center of Naples (Italy), taking into account several points of view.  相似文献

Understanding and dealing with the unknown is a major challenge in project management. An extensive body of knowledge—theory and technique—exists on the “known unknowns,” i.e., uncertainties which can be described probabilistically and addressed through the conventional techniques of risk management. Although some recent studies have addressed projects where the existence of unknown unknowns (unk unks) is readily apparent or may be assumed given the type of project—e.g., new product development or new process implementation—very little work has been reported with respect to projects in general on how a project manager might assess its vulnerability to unk unks. In this paper, we present a conceptual framework to deal with (i.e., recognize and reduce) knowable unk unks in project management. The framework is supported by insights from a variety of theories, case analyses, and experiences. In this framework, we first present a model of the key factors—relating to both project design and behavioral issues—that increase the likelihood of unk unks and a set of propositions linking these factors to unk unks. We then present a set of design and behavioral approaches that project managers could adopt to reduce knowable unk unks. Our framework fills a gap in the project management literature and makes a significant practical contribution: it helps project managers diagnose a project to recognize and reduce the likelihood of unk unks and thus deal more effectively with the otherwise unrecognized risks and opportunities.  相似文献

This paper examines a parametric estimating technique applied to technology-driven projects. Parametric cost estimating is a widely used approach for bidding on a contract, input into a cost benefit analysis, or as the pre-planning tool for project implementation. Extensive literature reviews suggest that effective parametric estimating methodology is becoming an essential tool for technology-driven organizations. The use of parametric estimating in budgeting, scheduling, and control of projects will enhance the ability of project management organizations to effectively and efficiently utilize valuable resources. The benefit of parametric estimating is its use as an estimating model for better determining potential resource requirements during the project pre-planning and conceptual phase.  相似文献

This article focuses on the opportunities for capabilities exchange within a specific business-to-business context: the relationship between a client and an information technology (IT) supplier. Research on the features of this type of relationship, although fairly extensive, has focused on IT implementation issues, relationship between IT resources, organisation performance and competitive advantage, IT outsourcing relationships and definition of IT capabilities. However, our understanding of the context where IT capabilities are exchanged within consultancy projects and how this exchange emerges is rather limited. The paper aims to bridge this gap by adopting the Industrial Marketing and Purchasing (IMP) group's interaction approach as a tool for conducting an in-depth investigation of a case study to analyse the context, the parties and the interactions through which IT capabilities are exchanged. The research reveals that interpersonal relationships between users and consultants within consultancy projects are crucial to establish a long-lasting and stable relationship. As a result, during consultancy projects IT-related resources, in the form of IT physical infrastructures, human IT resources and IT intangible resources are exchanged and combined to create or enhance IT capabilities. Furthermore, we also claim that the success of such an exchange depends very much on the degree of social and interpersonal exchange.  相似文献
