The influence of business strategy on project portfolio management and its success — A conceptual framework

Firms are facing more difficulties with the implementation of strategies than with its formulation. Therefore, this paper examines the linkage between business strategy, project portfolio management, and business success to close the gap between strategy formulation and implementation. Earlier research has found some supporting evidence of a positive relationship between isolated concepts, but so far there is no coherent and integral framework covering the whole cycle from strategy to success. Therefore, the existing research on project portfolio management is extended by the concept of strategic orientation. Based on a literature review, a comprehensive conceptual model considering strategic orientation, project portfolio structuring, project portfolio success, and business success is developed. This model can be used for future empirical research on the influence of strategy on project portfolio management and its success. Furthermore, it can easily be extended e.g. by contextual factors.     

Impact of relationship value on project portfolio success — Investigating the moderating effects of portfolio characteristics and external turbulence

Companies today need project portfolio management (PPM) to cope with the increasing number of projects and use it to ensure comprehensive management, strategic alignment, and efficient use of resources. Moreover, customers are demanding more value from their suppliers. The management of a project portfolio and the corresponding customer relationship portfolio implies a link between PPM and relationship management. By combining the fields of PPM and marketing, this study hypothesizes a connection between relationship value and project portfolio success. Because both parties need to extract value from a relationship, relationship value is divided into relationship value for the customer and relationship value from the customer. The results are based on a cross-industry sample of 174 German, Swiss, and Austrian medium-sized and large companies and rely on two informants from each firm. We find a significant relationship between relationship value and project portfolio success as well as moderating effects of portfolio interdependency, portfolio size, and technological turbulence.     

The moderating effect of human resource management practices on the relationship between knowledge absorptive capacity and project performance in project-oriented companies

In response to recent calls for research on human resource management (HRM) in project management, this research investigates the links between HRM practices, the project team's knowledge absorptive capacity (ACAP) and project performance in project-oriented companies (POCs). Based on survey data from 198 projects in multinational companies (MNCs) in the Thai automotive industry, this research finds that HRM practices moderate the effects of a project team's knowledge ACAP on project performance, in particular of potential ACAP on long-run project performance. In addition, HRM practices covary with a project team's realized ACAP, the other dimension of ACAP, to affect short-run project performance. This research sheds light on the different roles that HRM practices play in a project, finding that HRM practices not only facilitate knowledge management from the current project to future projects but also strengthen the relationship between a project team's knowledge ACAP and long-term project performance. This research contributes to the understanding of HRM in the literature of project management.     

The effects of project uncertainty and risk management on IS development project performance: A vendor perspective

The structural contingency perspective has been widely used in information systems development (ISD) project risk management research. This paper develops an integrative model to explore the moderating effects of uncertainty on the relationship between risk management and IS development project performance from a vendor perspective, rather than the client perspective that is mainly employed in the literature. A survey-based research design is used to collect data to test the proposed model. The results reveal that project uncertainty can moderate the effects of project planning and control on process performance and the effects of user participation on product performance. More specifically, the results indicate that project planning and control makes a greater contribution to process performance when there is a low level of inherent uncertainty and that user participation makes a greater contribution to product performance when there is a high level of inherent uncertainty. The results of this study contribute to a more acute understanding of the contingency approach to ISD project risk management.
