The first in-first out rule does not seem the most appropriated to manage the access of patients to health exams or services such as surgery. Indeed, each patient has his/her level of urgency and, furthermore the utility that each patient retires from the service differs according to several clinical but also risk and social related aspects. The decision of which patient to prioritize is tough because, in the current context where capacity is much lower than demand, choosing one patient means to delay others. Thus, this paper proposes a project methodology to prioritize patients into a Urodynamic service. The methodology, developed by a multidisciplinary team, is applied in a public hospital in Brazil, taking into consideration clinical and social criteria. We interviewed Urodynamics specialists, and a Fuzzy-AHP method is used to compute the weight of each criterion. Our preliminary results show the potential of the proposed methodology and methods, and that not only for the described case, but to other health services facing similar problems.

Project Finance addresses the need to secure large-scale, capital-intensive investments in face of expenditure restraint. Efficiency and a more logical distribution of risk among stakeholders are major advantages. The high amounts involved and the usually high proportion of debt—millions, in any currency—call for detailed risk analysis and risk allocation. In Project Finance there is limited or no recourse over the sponsor's assets and so investors rely on future cash flows for profitability. Growth prospects are therefore preferred to absolute values at any given time. However, most investors still decide based on the Net Present Value (NPV) of an opportunity, and use risk-adjusted discount rates to cope with uncertainty. This additional mark-up can ultimately turn down an otherwise profitable venture. By making the continuous-time behaviour of cash flows visible, simulation models based on System Dynamics avoids these drawbacks and provides a method to assess and manage financial risks that takes growth into account.

Fear of flying has no direct relationship with actual airline or aircraft safety. For those afraid of flying, the choice of an airline ticket and the related airplane is expected to be an important issue. This article uses a methodology to simulate the experience of purchasing unlabeled airline tickets to investigate whether individuals who are afraid of flying unconsciously change their choice depending on the ticket parameters. The Boeing 737 MAX, which became notorious for being grounded due to two recent accidents, was randomly assigned to airline tickets. This aircraft was compared with eight competing alternatives. The results demonstrate that in the event of a return to service, the passenger preference for this aircraft would be low comparable to that for competing modern airplanes that are less known to the North American public. Nonetheless, Boeing products continue to instill a sense of safety and trust in those afraid of flying.

This article investigates the phenomenon of compelled circumstantial trust, which project managers are subject to when performing their functions in the project environment. The objective is to contribute to project manager‘s higher productivity and efficiency. Compelled circumstantial trust is a phenomenon that happens, for instance, when there is a change of any key stakeholder in the project environment, or when a new project manager takes over the project. Therefore, it is necessary to trust the administrative legacy inherited and those who are part of it, which may represent a potential problem for an efficient project management model and become a challenge for the project manager, and ultimately for the sponsor. This article discusses compelled circumstantial trust and presents a validated scale, together with a set of practices that aims to improve the performance of project managers in the exercise of their duties, while keeping the privileges and particularities of their role.

Scaled Agile introduces challenges that confront organisations. One of these challenges is how initiatives are aligned with the organisational strategies in frameworks such as SAFe. Nineten interviews were conducted within a case that has implemented a scaled Agile framework. The purpose was to determine how this framework was implemented and to assess how information technology (IT) initiatives are aligned with the corporate strategies. The results indicate that IT initiatives are aligned with the strategies but that two approaches are used. Future research will focus on benefits realisation within a scaled Agile environment.

It is the state of the practice in these turbulent times to combine different approaches and project management methods into hybrid and adaptive methods according to the specific needs of the project and the project team. The objective of the present work is to investigate this practice conducting a systematic literature review on project management methods, hybrid agile methods, method tailoring and innovative processes to tailor methodologies. We applied a systematic analysis of the existent research published during period 2000 – 2020 following similar approaches of several scholars. 1.121 articles published from 2000 until 2020 were collected after exhaustive literature search. However, 98 of them were selected for further investigation according to the criteria selection. Results provide key insights and background on agile project management frameworks as well as challenges and best practices implementing an inhouse hybrid agile project management framework. We anticipate the present work to constitute a useful source of information to PM scientists and practitioners. Results identify new dimensions emerging of the synthesis of project management aspects and provide key insights on traditional and agile project management frameworks as well as challenges and best practices implementing an inhouse tailored hybrid agile project management framework. This work contributes to the body of knowledge about the organization mainly of agile and hybrid approaches. We analyzed the found descriptions thoroughly regarding their characteristics and their organization.

This study approaches the scenario of the literature on Lean an Agile Project Management, exploring synergies and complementarities, tools and practices. It is a literature review, applying bibliometric analysis of networks generated using VOSViewer Software and content analysis that explores a coding schema, draw through an in-depth analysis of the selected papers. The results show that Agile Project Management is becoming spreadably used; however, Lean Project Management still faces diffusion difficulties beyond the construction sector. For theory, it provides an overview of the literature, exploring methods, tools, and values of both approaches, pointing out the research opportunities and gaps. For practice, it identifies the main tools and the organizational contexts for applying Agile and Lean Project Management, helping in decision-making.

Like complex projects in other sectors, space projects frequently exceed cost and schedule performance targets. Reasons frequently cited for this include excessive optimism at the start of projects, political interference, technology development challenges such as design flaws and rework, changes to the work content during the project, and integration issues. Problems with progress can rarely be isolated to just one aspect of a project or system, however, and decisions taken in one part of a project to remedy a perceived problem may have unanticipated consequences later, elsewhere in the project. Based on data from a space science institute, this research presents a model of project progress to understand the effectiveness of the strategies available to managers of complex instrumentation projects. The paper focuses on the decision making around staffing when progress falls behind schedule and finds that practical challenges in expanding capacity in a team may mean that schedule slippages experienced early in the project lifecycle are unlikely ever to be reversed, even if additional resources are made available. This reinforces the importance of comprehensive risk analysis, thorough cost and schedule estimating at the start of the project, and the availability of realistic funding from the outset.

Products based on the Internet of Things (IoT) concept use a combination of physical devices embedded with sensors, other electronic hardware, software and the Internet to utilize meaningful data. Recently there has been a boom in IoT projects, but many of these projects are failing. One of the major reasons for this failure is a lack of specific project management methodologies that appropriately deal with the complexity and interdisciplinary nature of IoT projects. This article looks at the existing literature to find business, management and technical issues with these projects. In order to find solutions to these issues, various IoT stakeholders were surveyed and asked about which tools, processes and management strategies they find most useful. Ultimately, the goal of this article is to provide detailed knowledge about the existing IoT management philosophies, tools and their challenges, pros and cons, and how to scale these to improve the success rate of such projects.

The literature addressing the subject of projects and megaprojects governance is somewhat incipient and ambiguous. This work aims at a discussion of the possible contribution of the business policy approach as a means to overcome this gap in the practical governance of megaprojects. The category of megaprojects was chosen because they are organizations with some resemblance to companies in the wider sense of the word, despite some fundamental differences. Within the scope of megaprojects, we find a governance architecture that parallels the double tier of traditional corporate governance models. Project directors usually have a team similar to that of traditional companies. This can be envisioned as the executive board or managing structure of a traditional company. But these sorts of projects generally have a project steering committee, which is a non-executive governing structure addressing the scope of the project and which broadly considered might be compared with the non-executive board (or supervisory council) from traditional organizations. We propose for discussion an example of double tier project governance, approached from a business policy viewpoint, distinguishing executive from non-executive roles. The text ends by addressing the institutional configuration area of business policy in the context of megaprojects, as well as a reflexion on the validity of the points of view proposed.
