Leviticus Mensah, Richard Arhinful, Frederick Kitson Attabra, Hayford Asare Obeng

Goal: The study, grounded in the social cognitive theory, investigates the impact of project manager competencies on the perception of project performance, with project management practices acting as a mediator. Design / Methodology / Approach: A descriptive cross-sectional design was employed to collect data from 333 project managers involved in road and housing construction projects in Ghana, using snowball sampling. The data were analyzed using a Covariance-Based structural equation model (CB-SEM), with a focus on confirmatory and path analyses, which yielded significant insights. Results : It was found that project manager competencies have a positive and significant influence on the perception of project performance and project management practices. Interestingly, project management practices showed a negative influence on the perception of project performance. Moreover, project management practices were found to partially mediate the relationship between project manager competencies and perception of project performance. Limitations of the investigation: Due to financial constraints, several regions in Ghana were not covered, and the snowball sampling technique was used to recruit participants, limiting the physical accessibility of project managers used in the study. Practical implications: The study's recommendations for project managers in road and housing construction in Ghana to prioritize competency development, align practices with stakeholder perceptions, strategically implement practices, and continually evaluate and improve hold practical implications. Originality / Value: This study highlights the mediating influence of project management practices despite current research focusing on direct relationships. The research offers a novel perspective on improving project performance, particularly in developing countries, thereby significantly contributing to the existing body of knowledge.

Implementation Barriers for Digital Transformation of Perishable Food Supply Chain in Pakistan

Goal : This study aims to identify the key barriers affecting Digital Transformation (DT) in the Pakistan Perishable Food Supply Chain (PFSC) and to develop the contextual relationship between the identified barriers. Design/Methodology/Approach : This research adopted a hybrid approach, including qualitative and quantitative methodologies. In a qualitative section, potential barriers were identified through an extensive literature review and expert judgement. In the quantitative section, all identified barriers were analyzed using Total Interpretive Structural Modeling (TISM). Furthermore, Fuzzy-MICMAC (Matrice d'Impacts Croisés Multiplication Appliquée à un Classement) was applied to categorize the barriers into four groups: independent, linkage, autonomous, and dependent, based on their driving and dependence powers. Results : The analysis reveals that lack of support, lack of reward and recognition, poor IT infrastructure, and high investment and maintenance costs exert a severe impact on the system. These barriers are the primary elements hindering the DT process, while other barriers pose a relatively minor role. Limitations of the investigation: Due to the subjectivity of the respondents, particularly those from Pakistan’s PFSC, the findings of this research may not be generalized. Implications : The study outcomes help Food Supply Chain (FSC) experts prioritize these barriers to ensure a seamless DT. This research also contributes to the existing body of knowledge by proposing a hybrid methodology that incorporates TISM and Fuzzy MICMAC. Further, the study results can be replicated across different sectors and regions. Originality/value : The originality of this study lies of the TISM approach, which enables field experts to identify barriers and plan strategies for their elimination.
