Formalization of project portfolio management: The moderating role of project portfolio complexity

Companies frequently implement formalization to improve success. Previous research has found supporting evidence for the performance-enhancing effects of formalization in both single project management and project portfolio management. However, there is no research on how formalization at the project level interacts with formalization at the portfolio level, or on how this interaction may impact success. This study investigates the interaction of formalization at both levels and examines the moderating effect of project portfolio complexity on formalization. Using a sample of 134 firms, this study shows that single project management formalization and, likewise, portfolio management formalization are directly connected to portfolio success. Simultaneous formalization at these two levels delivers a complementary effect, resulting in an increase in success that is more than additive. A contingency analysis confirms that the proposed positive effects become more prominent if complexity is high. Complexity measured as project interdependency has a stronger moderating effect than complexity measured as portfolio size.     

Behavior of internal stakeholders in project portfolio management and its impact on success

Stakeholder behavior and stakeholder management are key success factors within project portfolio management (PPM). This empirical study of 197 project portfolios investigates the effect of the intensity of engagement (IoE) of portfolio-internal stakeholders on project portfolio success. We show that the effect of stakeholders is phase-specific and that role clarity as a measure of PPM maturity affects the nature of the relationship between the IoE of stakeholders and portfolio success. The effects of the IoE of senior managers on success are not clearly positive with regard to strategic portfolio structuring and are even negative in operative portfolio steering in established PPM systems. In immature PPM systems, line managers tend to take advantage of their position in resource management. Surprisingly, the influence of portfolio managers in portfolio steering is insignificant. Altogether, this paper shows the diverse effect of the IoE of stakeholders on portfolio success. This study enriches project research by applying stakeholder theory to the project portfolio context and offers practical guidance for further professionalizing PPM.     

Project portfolio management information systems’ positive influence on performance – the importance of process maturity

Companies increasingly support their project portfolio management processes with specific software, and the market for IT solutions is growing. While project portfolio management information systems (PPMIS) promise to improve the quality of the management process and eventually portfolio performance, it is unclear whether they actually deliver on this promise. We lack empirical evidence regarding the actual benefits of PPMIS and knowledge on the conditions under which PPMIS application is most beneficial. Using a sample of 181 project portfolios, this study shows for the first time that PPMIS application is overall positively associated with the quality of portfolio management processes and project portfolio success. However, moderation analyses further reveal that these effects only materialize when formalization of single project management, project portfolio management, and risk management are sufficiently high. Surprisingly, the benefits of PPMIS application do not depend on portfolio complexity (size, project interdependency, dynamics).     

Project portfolio management in practice and in context

Companies struggle with the sub-optimization and changes among their projects, even if various normative instructions and good practices have been introduced for project portfolio management. At the center of this paper is the need to understand project portfolio management in practice and in context. The purpose is to report a review on recent empirical research literature regarding project portfolio management, to draw attention to the limitations with viewing portfolio management as a rational decision process, and to develop new avenues for research regarding project portfolio management in practice and in context. As a result, this paper shows that, to respond to uncertainties and complexities in business environments, project portfolio management can be viewed as negotiation and bargaining and as structural reconfiguration, besides rational decision processes. These alternative perspectives offer new insight into the dilemmas identified in day-to-day project portfolio management and open up avenues for resolving them, thereby promoting success in project portfolio management.     

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 integration of ideation and project portfolio management — A key factor for sustainable success

Effective management of single projects is no longer sufficient. In today's business market, proactive management of the whole project portfolio has become increasingly important for achieving long-term success and competitive advantage. At the front end of projects, opportunities are discovered, ideas are created, and the foundation for later project, portfolio, and, eventually, corporate success is laid. This paper contributes to the project management body of knowledge by combining the front end view on projects with the holistic view of managing project portfolio landscapes. It focuses on establishing a framework for conceptualization of the relationship between ideation and project portfolio management in product development environment by relating ideation portfolio management, front end success, and project portfolio success, and lays the groundwork for further empirical research. The overarching topic I address is the conceptualization of how ideation can facilitate and sustainably improve portfolio success in the product development environment in the long-term.     

The three roles of a project portfolio management office: Their impact on portfolio management execution and success

Project portfolio management offices (PPMOs) are a subset of project management offices (PMOs) that handle collections of multiple single projects and programmes, i.e. portfolios. PPMOs are centralised organisational units that cater to the demands of various stakeholders by performing specialised tasks. They are initiated by their organisation's leadership in response to increasing management challenges originating from project portfolios. Although there has been considerable research on PMOs in general, not only a clear understanding of multi-project PMOs' activity patterns set in specific contexts like project portfolio management, but also both existence and mode of multi-project PMOs' contribution to successful performance are still lacking. By quantitatively analysing PPMOs in 278 portfolios, we identify three different activity patterns, which are interpreted as distinctive roles. We show a significant positive effect of PPMOs' coordinating and controlling roles on performance in terms of project portfolio management quality, which is a predictor of portfolio success.     

Impact of customer integration on project portfolio management and its success—Developing a conceptual framework

The growing number of company projects requires comprehensive management, project portfolio management (PPM), for strategic alignment and efficient use of resources. In parallel, companies face customers demanding higher value, and joint value creation with customers is considered a key success factor in the future. Project portfolios delivering products and services for customers implicate a link between PPM and an increased customer focus. Combining the research fields of marketing and PPM for the first time, this study proposes customer integration into PPM. I develop a framework describing the impact of customer integration into PPM on project portfolio success mediated through relationship value. Furthermore, the study describes relevant aspects for customer integration on the project portfolio level and identifies interfaces for cross-functional integration of a customer portfolio representative within the PPM process. The findings and limitations of this study are discussed, and further research is suggested.     

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.     

Contemporary project portfolio management: Reflections on the development of an Australian Competency Standard for Project Portfolio Management

Project portfolio management is an emerging aspect of business management that focuses on how projects are selected, prioritised, integrated, managed and controlled in the multi-project context that exists in modern organisations. Competency standards have been developed by professional bodies for project managers. However, to date there has been no attempt to develop a competency standard at the portfolio management level. This paper examines the process for development of the first performance-based competency standard for project portfolio management and identifies how this contributes to the body of knowledge in both project portfolio management and project management more broadly. The intent is to use the Standard to improve project portfolio management capability and practice in organisations, which in turn promotes efficient resource use and more profitable project outcomes. Specific issues regarding Australian practice are described, along with implications for how this may impact Australian practice in the future.     

Modeling project criticality in IT project portfolios

Today's IT project portfolios (ITPP) contain many projects and varied interdependencies. Depending on a project's criticality to the ITPP, a failure can have massive consequences. However, existing methods usually only assess overall project portfolio risk and do not account for the criticality of single projects and their dependencies. Applying Bayesian network modeling to ITPPs, we bridge this gap and extend the current body of knowledge for the information systems and project management literatures. Our new method analyzes single projects' criticality in a portfolio context by considering both transitive dependencies and different dependency types in an integrated way. Since we demonstrate that single projects' criticality can vary substantially, being aware of which projects are critical is a key success factor for ITPP management. For practitioners, our method provides a straightforward procedure to enhance ITPP risk management.     

Microfoundations of project portfolio regulation in joint university-industry laboratories

Joint university-industry laboratories (joint U-I labs) consist of a new, yet little understood model of academic partnership with the firms, typically involving the establishment of a collaborative research unit to conduct research and development (R&D) projects. This type of collaboration faces an ongoing challenge in dealing with the tension between the development and deployment focus in the project portfolio. While several studies have investigated project portfolio management in a given firm, little is known about the interorganizational portfolio management and how the actors manage tensions in joint U-I labs. This study aims to investigate the microfoundations of project portfolio management in joint U-I labs. By combining the multiple-case study and at-home ethnography methods, we identified that the regulation approach explains how partners in joint U-I labs dynamically adjust and manage the project portfolio. Based on the empirical findings, we propose a new framework for project portfolio management in joint U-I labs: portfolio regulation. This framework consists of four processes: dual scouting, dual matchmaking, joint selection, and bridgemaking. These microfoundations enable actors to strategically regulate the portfolio by increasing/decreasing resources related to development or deployment. Our study explores how portfolio regulation evolves within a joint U-I lab through four stages: formation, learning, reconfiguration, and joint portfolio. The proposed framework contributes to interorganizational R&D portfolio management theory and joint U-I lab portfolio management practice.     

The interplay between dynamic capabilities’ dimensions and their relationship to project portfolio agility and success

Recent literature emphasizes agility's importance for a project portfolio's success in a dynamic environment. Conceptually, dynamic capabilities should be relevant antecedents for portfolio agility since they help organizations cope with dynamic environments. Dynamic capabilities disaggregate into three dimensions: sensing market and technology opportunities, seizing opportunities through prioritizing and exploiting them, and continuously reconfiguring assets and structures. Although previous literature emphasizes the importance of dynamic capabilities for project portfolio management (PPM), former research rarely analyzed dynamic capabilities in PPM empirically. Further, dynamic capabilities can be conceptualized differently, and it remains unclear how different conceptualizations coexist and what effects they have on the results of a study. This paper quantitatively investigates the relationship between dynamic capabilities’ dimensions (sensing, seizing, and reconfiguring) and project portfolio agility and success using a multi-informant, cross-industry sample of 135 project portfolios. The findings show that dynamic capabilities positively relate to portfolio agility and that portfolio agility mediates the relationship between dynamic capabilities and portfolio success. Surprisingly, sensing, seizing, and reconfiguring do not have entirely complementary effects. Instead, at least two of the three dimensions must be strongly present to enhance portfolio agility positively. The study underscores the importance of dynamic capabilities for portfolio agility. It contributes to the literature on portfolio agility in PPM and a more differentiated view of dynamic capabilities' dimensions and their consequences.     

Exploring the roles of portfolio steering committees in project portfolio governance

Governing project portfolios engages different actors in organizations including portfolio managers, portfolio officers, top managers, and others who may team up as portfolio steering committees. While portfolio steering committees play a regular role in project portfolio governance, their role is still unclear. Through an in-depth multiple case study in three Danish companies, the roles of portfolio steering committees were explored. The results showed that portfolio committees may play three distinct roles in portfolio governance: a) communication and consolidation role, b) negotiation role, and c) decision making role. The results challenged the notion that portfolio committee meetings are the place and time to make collective decisions on the portfolio, rather, portfolio steering committees might unintentionally become or intentionally be used for other purposes than decision making. The empirical evidence of the study proposes that these three roles might be related to two governance design factors: frequency and duration of committee meetings.     

Examining the role of transformational leadership of portfolio managers in project performance

Research into the role of transformational leadership in project based organisations has generally focused on project managers or senior managers and less so on portfolio managers who oversee multiple projects to achieve business objectives. This study examines the impact of transformational leadership behaviour of portfolio managers on project performance directly and indirectly through other intervening variables such as climate for innovation and innovation championing. Using a questionnaire survey, data were obtained from 112 project managers in a UK project based organisation. Transformational leadership behaviour of portfolio managers was found to have a positive and significant relationship with project performance. Innovation championing and climate for innovation both partially mediated the relationship between transformational leadership and project performance. The study confirms the importance of portfolio managers in enhancing project performance and identifies the need for project based organisations to cultivate transformational leadership behaviour among them for enhanced performance. It also highlights the need for further exploration of the role of portfolio managers in improving project performance.     

The use of effectuation in projects: The influence of business case control,portfolio monitoring intensity and project innovativeness

Project management approaches are evolving to be more flexible and adaptive to meet the challenges associated with an increasingly complex and dynamic environment. However, potential changes in the underpinning logic supporting project decision making have scarcely been considered. We investigate the role of effectuation, a decision logic most commonly associated with entrepreneurship, as an alternative decision-making approach to the rational ‘causation’ logic that has traditionally underpinned project management processes. We develop and test a model to explore the portfolio- and project-level influences on the application of effectuation in project management. We find that portfolio governance mechanisms related to business case use and portfolio monitoring inhibit the use of effectuation, while project innovativeness is associated with increased use of effectuation. The paper contributes to research and practice by empirically investigating the antecedents to the use of effectuation decision-making logic in project and portfolio management through a multi-level model.

Strategic change towards cost-efficient public construction projects

The cost of public construction projects is a central topic in project management. However, studies have primarily focused on cost at the project level, not on cost management at the portfolio level. In this paper, we take the perspective of a government agency, conducting a strategic initiative to increase cost-efficiency in their portfolio of construction projects. We use an action research approach to investigate the dynamics of the initiative and the implementation of resulting actions to achieve lasting change towards cost-efficiency. Co-creating actions for cost-efficiency together with the project teams was important for the success of the strategic initiative. For successful implementation, alignment of the objectives of the initiative with organizational strategy, and knowledge transfer between projects is central. This study expands the project management literature regarding strategic cost management of portfolios of construction projects and provides practical guidance for organizations.
