This paper aims to propose an accurate and efficient decision-making process adapted to the specific context of Claim Management situations, implying partners engaged in a high-involvement relationship.

We used a three-step approach: first, an inductive phase based on 12 past case studies. Second, a theory-building phase. Third, a theory-testing phase based on an ongoing case study to observe and test our propositions.

Proposal 1: Partner’s Strategic Value is an influential decision parameter that must be incorporated into Claim Management-related decision-making processes in high-involvement relationships. Proposal 2: The Fast-and-Frugal Heuristic is adapted to the intense, interactive and iterative nature of the Claim Management context. Our final proposal combines these two findings, i.e. a Fast-and-Frugal Heuristic incorporating the Partner’s Strategic Value and based on using decision criteria as a sequence, not simultaneously.

In the context of high-involvement business relationships and Claim Management, this study introduces the importance of selecting an appropriate decision methodology and integrating a strategic decision parameter (Partner’s Strategic Value) into an operational decision-making context. Furthermore, the principle of considering decision parameters in a specific sequence corresponds to the iterative and interactive nature of the Claim Management processes.

The purpose of this paper is to better identify, define and model complexity within the field of project management in order to manage better under conditions of complexity (and manage better complexity‐induced risks).

An extensive literature review enlightens the lack of consensus on project complexity and thus provides a broad view and a critical analysis of the underlying concepts. A project complexity framework and definition are then proposed. After underlining the stakes of project complexity in accordance with these proposals, a project complexity model is then built notably due to systems analysis.

Proposal of standard project complexity framework and definition. Proposal of a synthesis of the relationships between the concepts of project uncertainty and project complexity. Proposal of a project complexity model (and validation due to industrial application).

The literature review and project complexity framework tries to be exhaustive even though it is likely to be completed. The final version of the model is still to be computed and tested.

Avoiding confusion when defining and managing a complex project, particularly between project team members (and as a consequence improving communication and information sharing), improves the assessment of the propagation of a change within the project.

The paper proposes an original framework and a definition of project complexity. The complexity model permits the navigation from any element of the project to any other (when detail is needed) and is, as a consequence, original and complementary with traditional project management models and tools.

The purpose of this paper is to develop the concept of project vulnerability in order to focus on the weaknesses of a project system, instead of focusing on risk evaluation only. The paper concentrates on a systems thinking‐based view to highlight the potentially endangered elements of a project, including its outcomes.

The paper gives a broad state of the art in many scientific domains; a definition of project vulnerability; a description of a project vulnerability management process, including identification, analysis and response plan; and a test on an industrial case study.

The author's project vulnerability management process permits one to concentrate directly on the existing weaknesses of a project system, which may create potential damages regarding the project values creation. By focusing on this system, response plans may be more adapted to the existing short comings of the project.

Some aspects of the vulnerability definition should be refined, like the concepts of susceptibility or cruciality. Other promising works may focus on the evaluation of the non‐resistance and resilience, notably thanks to the introduction of interdependences which exist in complex projects.

A case study was done on a decision support system (FabACT) developed at Hôpital Européen Georges Pompidou Pharmacy department. The aim of this project was to achieve a better balance between the workload and the efficiency of the compounding unit.

The paper presents an innovative way to analyse a project's vulnerability by focusing on its existing weaknesses using a systems thinking‐based approach.

The purpose of this paper is to provide a holistic and comprehensive historical perspective of the evolution of value management, and to illustrate the impact that value analysis can have on innovation within organizations.

A review of published material from credible sources describing the evolution of the value management methodology, and a desktop analysis of 35 documented value management case studies illustrating the role of value management in innovation.

Published descriptions of the evolution of value management are incomplete and fragmented. A holistic and comprehensive historical perspective of value management as a value-adding methodology is provided. Mapped against a model for innovation, value management is shown to contribute substantially to innovation within organizations across a variety of contexts. Value management is currently evolving into a powerful approach to strategic planning.

This paper illustrates the contribution of value management to innovation across a variety of industries and contexts.

The paper provides a holistic and comprehensive historical perspective of the evolution of value management as a methodology, and demonstrates by mapping selected case studies onto a model of innovation impact, that the method is a powerful and versatile approach to obtaining innovative solutions to organizational problems.

Cost and schedule overruns are rife in dam projects. Normative evidence espouses overruns as though they are inimical to development and prosperity aspirations of stakeholders. This study examines the causal relationship between project financing and overruns.

Causative data were extracted from completion reports of 28 major dam projects in Africa. Each of the projects was financed jointly by up to 10 international development lenders. Relationships between causes of overruns and project outcomes were analysed.

Analyses elicit indicators of remarkable correlations between finance procedures and project outcomes. Lenders’ disposition to risk attenuation was the main debacles to project success. Interests had mounted, whilst release of fund was erratic and ill-timed. Finance objectives and mechanisms were grossly inadequate for projects’ intense bifurcations. Projects had slowed or stalled because lenders’ risks attenuation processes were purposed to favour lenders’ objectives, and not projects’ interests. In addition, findings also show project owners’ own funds and the number of lenders to a single project correlate with overruns.

Findings imply commercial complexities around major projects. They also show transactions are shaped by subtle (mis)trust behaviours in project finance procedures. Thus, scholarly solutions to project performance issues should consider behavioural issues of stakeholding parties more broadly, beyond contractors and project owners. Project finance ecosystems are vulnerable to major actors’ self-interests, opportunism and predatory conducts. Borrowers would manage this by developing and improving their capacity to build resilience and trust. Evidence shows intense borrower nations in Africa have limited capacity and acuity for these.

This study contextualises megaprojects in complexity rather than cost. Its additionality is in how finance steers absolute control of project environment away from project owners and how finance administration triggers risks and overrun.
