Numerous surveys point at human factor as a source of this malheur. The question emerge to what extent project manager is responsible for improvements there, and which particular skills are demanded to turn the ICT projects course towards more predictable, more efficient and better budget able endeavours. Authors examined and compared the scientific and practitioners views. Twenty-nine journal and conference papers and 46 monographs and standards dedicated to project manager skills have been scrutinized. Further 324 jobs advertisements for the ICT project managers in USA, Switzerland, Poland and Thailand underwent an analysis related to the demanded soft skills of the project manager. The L-Timer~ taxonomy of human factor related processes in project management is applied as comparison vehicle. Methodology extracted main (global) terms and detailed aspects, both weighted appropriately. The practitioners on all continents expect primarily communication skills followed by the team management abilities. Human resource is partially treated, while conflict management is underrepresented. The science seems to be focused on leadership followed by the communication skills, neglecting self management skills of project managers. The last are surprisingly well represented in the US advertisement. The USA job advertisements are the most comprehensive and elaborated one--and, what might be explained by high impact of American science on job definition--close to the scientific details of skill description, self management excluded. In Poland, team management appears to be a problem, while Thailand's companies seek leaders first. The best balanced approach might be found in Swiss job advertisements. The inter-cultural differences point at impact of cultural heritage, which call for differentiated view of science on demanded project manager human factor related skills. Authors pursue this fascinating research.展开更多

However, there is still an awareness inadequacy of the 4IR among project managers and the society in Tanzania, thus low readiness to conceptualize, implement and manage 4IR-related projects in the country. This study aimed to assess the 4IR readiness of project managers in Tanzania. The assessment is made in the frame of 4 readiness dimensions: strategy and governance structure, technology awareness, human capital digital skills development, and social-economic impact. The research used a quantitative method with the diffusion of innovations theory perspective, and data were collected mainly through an online survey questionnaire. The survey aimed at answering the research question concerning the project managers’ readiness for the 4IR. The 50 valid samples were completed by project managers from various industries such as agriculture, finance, consulting, construction, education and training, government, healthcare, Information Technology, and manufacturing. Data were analysed using SPSS. The results revealed that despite the generally low awareness of 4IR, several project managers in Tanzania have some varying awareness of 4IR technologies such as artificial intelligence, Internet of Things (IoT), data analytics, blockchain, robotics, cryptocurrency, chatbots, drones, and other digital transformation platforms. The results also indicated that project managers in Tanzania had little extent in readiness to initiate, develop and implement 4IR products and services due to inadequate 4IR-related awareness, strategy and governance structure, human capital digital skills development, and social economic impact. Consequently, some recommendations are made in the frame of the four assessed readiness dimensions for improvement. The value of this research is mainly to provide the state of 4IR readiness of project managers and associated recommendations to policymakers, practitioners, academia, donors, business industry and youth in digital innovation. The study also contributes to the body of knowledge on 4IR, project management and digital transformation.展开更多

It has evolved from the conventional cartography and image processing to advanced 3D visualization and dynamic graphics tools. Due to this evolving nature of GIS, it has found wide applications in a number of diverse fields. Geophysical exploration projects involve data acquisition at hundreds of spatial locations resulting in large number of datasets. It takes a great deal of time to manage all these datasets during data processing and interpretation. This paper presents the use of GIS as an effective project management tool, providing an interactive data access interface in compute intensive geophysical processing applications. A reusable GIS software component is presented which can be used by geophysical applications to manage their datasets. A practical example is included to demonstrate the implementation of this GIS component as an embedded Project Manager in a seismic refraction software.展开更多

Yet, there is less evidence of empirical research on what factors contribute to this outcome. This study aimed to bridge this gap by examining the effects of contractor-related factors on the performance of bridge construction projects in Kenya through a case study of the Bridge projects Implemented by the Kenya National Highway Agency (KeNHA). The theory of constraints (TOC) was adopted as its theoretical framework. Descriptive research was used, and the target population was 18 bridge construction projects, which were the units of analysis from 2012 to 2022. In each of these projects, 18 respondents, namely clients, consultants, contractors, engineers, environment and social guards, project managers, stakeholders, subcontractors, technical advisors, and inspectors, were included in a target population of 144 respondents. A census was conducted and a structured questionnaire was administered from which a response rate of 68% was achieved. The information was analyzed using descriptive, correlation, and multiple linear regression analysis. The contractor-related factors considered in the study were staff and management factors. The findings indicated that staff and management factors had a positive and significant outcome on performance of bridge construction projects. The study recommends continuous training and a safe learning environment for staff to improve their skills and performance in future projects. The study also recommends that a special category for bridge contractors be created in Kenya’s National Construction Authority rankings to ensure that only qualified contractors implement the Bridge projects.展开更多

A social project is considered as a project system based on a set of measures of social orientation; has specific objectives; and is located in space and time-restricted. The sample data of 25 in-depth interviews with representatives of the business community, public authorities, and civil society institutions, all active participants in community development in the Voronezh administrative region served as an empirical basis for this paper. The analysis of respondents' views on the importance of social projects has enabled to define their descriptive and normative features. The main descriptive features include the following: overcoming specific urgent problems in a society; implementing state social policy; quantitative changes in the material life conditions of an individual or a social group; creating labor markets; implementing social innovations; two-way influence of the quality and quantity of social projects and the level of socio-economic structure (company, region, country). Normative features include: encouraged development of state institutions; stability of the environment; balanced socio-economic development; formation of a community of reasonable individuals; development of human potential. Conclusions have been made about the nature, characteristics, and goals and objectives of social projects and their role in social and economic development of the region, spheres of social projects implementation significant for Russia, about active participants, success and failure factors of social projects, prospects and intensity of social engineering in the Voronezh administrative region and Russia as a whole. Soft systems methodology has been used for stating and structuring the empirical data. The results obtained have enabled to lay the foundation for finding the concepts and mechanisms to coordinate the participants in community development.展开更多

In the construction industry, project consultants play a very significant role in providing services for such projects. The project consultants provide services from the beginning of the project to the completion of the project. Using project consultants is very useful for construction projects because it can ameliorate project efficiency and effectiveness. The main purpose of this paper is to investigate the relationship between project consultants’ performance and project success in the Rwandan construction industry. The data used in this study were obtained from primary and secondary sources. The secondary data was attained through an elaborated literature review of various books, articles, and papers related to this research to outlining and describing the chief ideas of this research title. The primary data was compiled through a questionnaire survey that was directed to 110 selected professionals in the construction projects in Rwanda to collect data from the site for statistical analysis of the research to test the hypothesis. However, a total of 90 usable responses were received within the scheduled period representing the response rate of 81.82%, which is likely to be representative and acceptable. Data collected from the questionnaire surveys were analyzed using the Statistical Package for Social Scientists (SPSS), excel spreadsheets, and Relative Importance Index (RII), which provide more merit presentations. The survey results show that even if there are many obstacles in the use of project consultants in the Rwandan construction industry such as lack of knowledge and practice in project consulting, lack of well-trained project consulting professionals, lack of training opportunities in project consulting, lack of knowledge and experience in addition to the senior management opposition, and lack of local project consulting guidelines and information;they are needed in the construction project to make it more successful through reducing and saving the overall project’s life cycle cost according to client’s wishes, keeping time of construction project, improving quality of the project products in the present and future, removing major variations that affect construction project with its attendant cost overrun, and advising on construction project process. Therefore, it is more important to remark that the good performance of the project consultants in any industry especially in the construction industry will contribute to the successful implementation of the project. From the results of the study, the performance of project consultants is closely related to the success of the construction industry in Rwanda. The project consultants’ leading skills and knowledge automatically guide the project to complete with accurate time, budget, and quality to make the project successful. In this paper, we will also consider the project success criteria;the role and responsibility of project consultants;the factors affecting the performance of project consultants;and the reasons that hinder the implementation of project consulting in the Rwandan construction industry.展开更多

This paper focuses on the coping narratives developed by contract team members during the building phase of a large-scale infrastructural project. Coping narratives relate to the management based grand narrative of the project and are produced and shaped in the process of sense making. By analyzing this interaction and the developments in a specific sub-team of a project, which is faced with multiple identity claims, this paper aims to contribute to the knowledge on how policies, views and decisions on an organizational level work out in project teams. The empirical material relates to a recent Dutch Mega-Project regarding the construction of a new sea defense and boulevard in Scheveningen. This paper shows that developments, discourses and decisions on an organizational level are of importance for the commencing coping narratives in project teams.展开更多

文摘As discovered, today’s Rwandan construction industry is developing day by day, which plays a very important role in the country’s economic growth. In the construction industry, project consultants play a very significant role in providing services for such projects. The project consultants provide services from the beginning of the project to the completion of the project. Using project consultants is very useful for construction projects because it can ameliorate project efficiency and effectiveness. The main purpose of this paper is to investigate the relationship between project consultants’ performance and project success in the Rwandan construction industry. The data used in this study were obtained from primary and secondary sources. The secondary data was attained through an elaborated literature review of various books, articles, and papers related to this research to outlining and describing the chief ideas of this research title. The primary data was compiled through a questionnaire survey that was directed to 110 selected professionals in the construction projects in Rwanda to collect data from the site for statistical analysis of the research to test the hypothesis. However, a total of 90 usable responses were received within the scheduled period representing the response rate of 81.82%, which is likely to be representative and acceptable. Data collected from the questionnaire surveys were analyzed using the Statistical Package for Social Scientists (SPSS), excel spreadsheets, and Relative Importance Index (RII), which provide more merit presentations. The survey results show that even if there are many obstacles in the use of project consultants in the Rwandan construction industry such as lack of knowledge and practice in project consulting, lack of well-trained project consulting professionals, lack of training opportunities in project consulting, lack of knowledge and experience in addition to the senior management opposition, and lack of local project consulting guidelines and information;they are needed in the construction project to make it more successful through reducing and saving the overall project’s life cycle cost according to client’s wishes, keeping time of construction project, improving quality of the project products in the present and future, removing major variations that affect construction project with its attendant cost overrun, and advising on construction project process. Therefore, it is more important to remark that the good performance of the project consultants in any industry especially in the construction industry will contribute to the successful implementation of the project. From the results of the study, the performance of project consultants is closely related to the success of the construction industry in Rwanda. The project consultants’ leading skills and knowledge automatically guide the project to complete with accurate time, budget, and quality to make the project successful. In this paper, we will also consider the project success criteria;the role and responsibility of project consultants;the factors affecting the performance of project consultants;and the reasons that hinder the implementation of project consulting in the Rwandan construction industry.

文摘Recent studies on collaborative practices in large infrastructural projects address the importance of discursive strategies and power relations in dynamic project arenas [1]-[3]. This paper focuses on the coping narratives developed by contract team members during the building phase of a large-scale infrastructural project. Coping narratives relate to the management based grand narrative of the project and are produced and shaped in the process of sense making. By analyzing this interaction and the developments in a specific sub-team of a project, which is faced with multiple identity claims, this paper aims to contribute to the knowledge on how policies, views and decisions on an organizational level work out in project teams. The empirical material relates to a recent Dutch Mega-Project regarding the construction of a new sea defense and boulevard in Scheveningen. This paper shows that developments, discourses and decisions on an organizational level are of importance for the commencing coping narratives in project teams.
