The issue of assessing the effectiveness of a project of an ecologistic system using the criterion of «a discounted payback period», which takes into consideration the transformational changes in the project life cycle, was considered. The specific features of the life cycle of a project of an ecologistic system, in the structure of which it is proposed to include environmentally-oriented regeneration and revitalization phases, were explored. The phases of a life cycle were divided into stages, between which consecutive and parallel relations were established. The project life cycle consists of time intervals, during which from one to three stages of the project phases can run in parallel. A model of the life cycle of an ecologistic system, which shows the relations between time intervals and cash flows that correspond to the stages of the project life cycle phases, was developed. A mathematical formula for calculating the discounted payback period of a project, which takes into consideration the specific features of the formation of cash flows of separate phases of the life cycle of an ecologistic system, was proposed. The application of the formula is possible when assuming the constancy of cash flows of the stages of operational and the regeneration phases, which corresponds to the conditions of uncertainty of their forecasting at the beginning of the project. The functional dependences between the discounted payback period and cash flows during the phases of a project life cycle were studied. Depending on a phase of the life cycle, the dependence is expressed by a linear, polynomial, or power function. The identification of functional dependences makes it possible to study the dynamics of changes in the discounted payback period with changes in project cash flows, which can be used in forecasting the effectiveness of an ecologistic system project.

Purpose Public‐private partnerships (PPPs) are being faced by risk threats, notwithstanding the fact that the PPP model has been structured in a way that the associated risks are shared by both the public and private sectors. Consequently, the sources of risk change over the PPP project phases. Thus, the purpose of this paper is to identify and assess the risk factors in PPP infrastructure project phases comprising development phase, construction phase, operation phase and project life cycle through an empirical approach. Design/methodology/approach The study adopted four different data-gathering approaches including literature review, desk review, brainstorming session and questionnaire survey. In order to capture a broad perception of stakeholders, the questionnaires were administered to three different stakeholder organizations to include public sector authorities (i.e. ministries, department and agencies), concessionaires and lenders/banks involved in different PPP infrastructure projects implementation in Nigeria. A total of 81 questionnaires were administered, out of which 63 were retrieved but after checking through the completed questionnaires, 60 questionnaires were found suitable for the analysis. Data collected were analyzed using descriptive statistics, mean score, Kruskal–Wallis test and the risk significance index in terms of severity and likelihood of occurrence conducted. Findings In total, 70 risk factors were identified with respect to PPP project phases and their relative importance was gauged. In addition, the analysis of total 70 risk factors in the development phase, construction phase, operation phase and project life cycle phase indicated that 51 risk factors are located in the yellow zone, which is considered as moderate and 19 risk factors are located in the red zone that are regarded as critical. Practical implications The identification of specific critical risk factors in each PPP project phase will provide a benchmark in developing risk management programs in developing countries. Originality/value These study findings would be useful for PPP stakeholders to focus their attention, priorities and leadership in managing these critical risk factors. Furthermore, the findings of this study are significant in providing an in-depth understanding of the current Nigeria’s PPP market environment, which is a true reflection of developing countries as a whole.

Cycle Efficiency

The article deals with the implementation of innovative projects, involving a comprehensive assessment, reflecting the integral efficiency of the most significant indicators. The features of innovative projects in large innovation and production clusters, projects that are strategic in nature and affect the activities of the enter-prise in the long term are considered. The principles of analyzing the effectiveness of the projects under study when choosing methods for assessing the effectiveness of innovative projects and the need to discount cash flows are presented. The heterogeneity of the assessment of the effectiveness of an innovative project at various stages of the project life cycle, efficiency in general, the effectiveness of participation in the project, social efficiency and budgetary efficiency are noted. It is summarized that the inflows and outflows used in assessing the budgetary efficiency of innovative projects vary significantly when moving from one level of budget efficiency research to another.

Different VLITP methodologies are capable of solving various types of problems during a project life cycle. This chapter shows that effect of VLITP methodologies can be widespread, especially in regards to project phases, resource allocation, project monitoring, adjustment of project scope, correction activities, and so forth. It reviews several methodologies that are often used to implement VLITP.

This article develops a framework for applying organizational narrative theory to understand project narratives that potentially perform and change the future. Project narratives are temporal but often get repeated throughout the project life cycle to stabilize meaning, and could be about project mission, vision, identity, value creation, and so forth. Project narratives have important implications for organizational identity and image crafting. This article differentiates among different types of project narratives in relation to a project life cycle, providing case studies of project narratives on three major UK rail projects. We then set out the future research agenda into project narrative work.
