Adoption Of E-Procurement Technology In Uganda: Migration From The Manual Public Procurement Systems To The Internet
(Journal of Supply Chain Management, 2018) Ahimbisibwe, Arthur; Wilson, Tusiime; Ronald, Tumuhairwe
Many public sector entities in Uganda face the challenge of delivering goods and services to consumers due to procurement constraints. The increased losses in the public procurement processes have been attributed to low adoption level of e-procurement as the ordinary manual procurement process has been blamed to be time consuming and has consistently scored low on achievement of value for money and transparency. Most Public Procuring and Disposing Entities (PDE’s) do not know how to adopt electronic procurement systems due to lack of understanding of procurement process automation. Yet, with the increased level of technology and automation, e-procurement is a necessary innovation that can increase level of efficiency and effectiveness of PDE’s. This study examines the e-procurement practices for adoption, the willingness and readiness to adopt e-procurement and investigates the challenges to the adoption of e-procurement practices in Uganda’s PDE’s. A quantitative and cross sectional survey was conducted using simple random sampling to select respondents from whom data was collected using self-administered questionnaires. The research enhances our understanding of e-procurement systems as the best practice technique in modern e-procurement system, an area which has been given less attention. Practical contributions are also discussed.
Ethical Work Climate and Ethical Attitudes of Procurement Officers: Empirical Evidence from Government Organizations in Uganda
(Operations Research Society of Eastern Africa, 2015) Mutebi, Henry; Ahimbisibwe, Arthur; Ntayi, Joseph M.
This paper aims at establishing the effect of ethical work climate on ethical attitudes of procurement officers working in Ugandan public entities. A cross-section research design was employed and primary data were collected from 89 government organizations. A sample of 198 procurement officers was drawn from the population of 393 procurement officers. A total of 190 usable questionnaires were returned, giving a 95 percent response rate. Findings from this study indicated a significant positive relationship between ethical work climate and ethical attitudes. Being a cross sectional study by its nature, subject to common method variances, a replication of the study using a longitudinal approach is recommended. This should be supplemented with more interviews from a cross section of procurement officers in these organizations to tap salient issues from respondents.
Formal Contractual Governance Mechanisms, Contract Contingencies, Inter-Organizational Trust, Supplier Opportunism and Outsourcing Performance
(International journal of business and behavioral sciences, 2012) Ahimbisibwe, Arthur; Nangoli, Sudi; Tusiime, Wilson
The purpose of this study was to explicate the influence of formal contractual governance mechanisms, contract contingencies, inter-organizational trust and supplier opportunism on outsourcing performance. This research was prompted by reports of increased poor outsourcing performance characterized by poor quality of services provided, incomplete and substandard work, failure to deliver on agreed schedules, increased user complaints and contract violations in Uganda’s public sector. Anecdotal evidence attributes poor outsourcing performance to lack of clearly designed formal contractual governance mechanism, failure to handle contract contingencies, lack of inter-organizational trust and existence of high levels of supplier opportunism. Hence this study was guided by the following research question: Do formal contractual governance mechanisms, contract contingencies, inter-organizational trust and supplier opportunism influence outsourcing performance? Cross sectional and quantitative survey data drawn from 612 contract managers in Uganda’s public sector (i.e. ministries, commissions and government parastatals) revealed that formal contractual governance mechanisms, contract contingencies, inter-organizational trust and supplier opportunism are significant predictors of outsourcing performance. Results of this study have managerial and theoretical implications that are presented in this paper.
Information Technology Capability, Adoption, Logistics Service Quality and the Performance of Third Party Logistics Providers
(International Journal of Operations and Logistics Management, 2016) Ahimbisibwe, Arthur; Omudang, Stephen; Tusiime, Wilson; Tumuhairwe, Ronald
The purpose of the study was to examine the relationships between IT capability, IT adoption, logistics service quality and performance of third party logistics firms in Uganda. The study was prompted by the delays in customs clearance; bureaucratic systems and lengthy cargo forwarding processes largely of manual nature that are evident among the activities of the third party logistics providers in Uganda. This could be attributed to lack of IT capability, low IT adoption and poor logistics service quality. A cross sectional data was collected from a sample of 80 registered Clearing and forwarding firms in Uganda selected from a population of 109 firms using a simple random sampling technique. Data was collected using a close ended questionnaire. The results indicate significant positive relationships between IT capability, IT adoption, logistics service quality and performance of third party logistics firms. Findings also revealed that IT adoption and logistics service quality are significant predictors of the performance of the third party logistics providers. However, IT capability was found not to be a significant predictor of performance of third party logistics providers. Findings further revealed that IT adoption was a better significant predictor of the performance of third party logistics providers than logistics service quality. The research recommends that clearing and forwarding firms in Uganda need to adopt IT quicker and increase logistics service quality in order to improve on the performances of their clearing and forwarding operations especially in the areas of documentation, cargo tracking, warehousing, and shipment operations.
Mediating Effects of Network Degree and Network transitivity on the Relationship between Project Communication Strategies and Perceived Project Success
(International Journal of Economics and Management Sciences, 2012) Ahimbisibwe, Arthur; Nangoli, Sudi; Tusiime, Wilson
The purpose of this study is to examine the mediating effects of social networks dimensions of network degree and network transitivity on the relationships between project communication strategies and perceived project success. This study was motivated by the increased failure of most philanthropic projects in Uganda to meet their explicit objects in terms of time, quality, and budget and enhanced corporate awareness which could be attributed to neglect of ‘soft’ factors. Although numerous classical studies have been undertaken in different domains involving project communication, social networks and perceived project success, no existing empirical study has examined the mediating effect of social networks dimensions on this relationship. A cross sectional data collected by a quantitative survey from all philanthropic projects conducted by commercial banks in Uganda, reveals that network degree is a significant mediator in the relationship between internal project communication and perceived project success while network transitivity is also a significant mediator in the relationship between external project communication and perceived project success Further, the findings confirm a partial mediation between project communication, social network dimensions and perceived project success. This study has both practical and theoretical implications that are well discussed.
Mediating influence of Individual Commitment and Social Networks on the relationship between Project Communication and Perceived Project Performance: A Structural Equation Modelling Approach
(European Journal of Business and Management, 2015) Ahimbisibwe, Arthur; Tumuhairwe, Ronald; Tusiime, Wilson
The purpose of this paper is to examine the mediating effects of individual commitment and social networks on the relationship between project communication and perceived project performance. Many citizenship projects frequently fail to deliver on time, budget, specifications, and quality or do not deliver value to the public. This could be attributed to ineffective project communication, lack of individual commitment and inadequate social networks. Design/methodology/approach–A theoretical model and hypotheses are developed from literature review. A cross sectional data set collected from 322 project stakeholders from Uganda is used to validate the model. Findings – Structural Equation Modelling results reveal that individual commitment and social networks mediate the relationship between project communication and perceived project performance. The results also suggest that social networks elements have a stronger influence towards project performance than individual commitment elements. Research limitations/implications – The study focuses on behavioural constructs as predictors of perceived project performance. Although these constructs are robust and sufficiently represent the human aspects, the multidimensional nature of behavioural practises can be investigated further. Similarly, since perceived project performance is contextual and evolutionary, additional constructs may be incorporated into the validated model. Practical implications–The findings suggest that individual commitment and social networks are mediators of project communication and perceived project performance. Managers of citizenship projects need to create social networks with their stakeholders to increase perceived project performance. Similarly, there is need to enhance individual commitment that increases the likelihood of perceived project performance. Originality/value-Many classical studies are reported in different domains involving these constructs; however no existing empirical study focuses on how they are linked together. This is the first paper to investigate and systemically document the mediating effects on this relationship.
Moderating Effect of Buyer-Supplier Trust on the Relationship between Outsourced Formal Contracts and Supplier Delivery Performance: An Empirical Study of Public Sector Procurement
(International journal of business and social science, 2012) Ahimbisibwe, Arthur; Nangoli, Sudi; Tusiime, Wilson
This study examines the moderating effect of buyer-supplier trust on the relationship between outsourced formal contracts and supplier delivery performance in the domain of public sector procurement. In so doing, we extend the paradigm that formal contracts and relational governance mechanism function as complements rather than substitutes. Using a cross sectional data from a survey of 612 staff that are involved in managing outsourced contracts in Ugandan public sector, Structural Equation Modelling results support 10 of the 14 hypotheses thus, demonstrating the fundamental preposition of complementarity between formal contracts and relational governance mechanisms. Also, findings revealed that well-structured outsourced formal contracts have a significant positive influence on buyer-supplier trust and supplier delivery performance.However, the path coefficient for the interactioneffect between change characteristics and buyer-supplier trust was initially hypothesised to positively influence supplier delivery performance but did not.The use of case studies and additional surveys in future research might help to explain this phenomenon. Although the two constructs of buyer-supplier trust and supplier opportunism are robust and sufficiently represent the relational aspects, the multidimensional nature of relational practises can be investigated further. This study has managerial and policy implications that are also discussed in this paper.
The Moderating Influence of Inherent Project Risk on the Relationship between Project Planning and Perceived Project Success
(International Journal of Supply Chain Management, 2015) Ahimbisibwe, Arthur; Tusiime, Wilson; Tumuhairwe, Ronald
Project planning is considered to be a critical success factor for project success. However, recent literature questions whether planning has similar importance in various project contexts. This research investigates the effectiveness of project planning on project success in various project risk contexts of software development projects. A survey based research design was used to collect data to test the proposed model. The results reveal that various inherent project risks moderate the effects of project planning on project success and in different ways for various success measures. More specifically, the results indicate that project planning makes a greater contribution to project success when there is a low level of inherent project risk and its positive impact on project success diminishes when there is a high level of inherent project risk. The results of this study contribute to a more acute understanding of the contingency approach to software project risk management. Practical implications of these results suggest that project managers should put more emphasis on less detailed formal planning in high risk project situations in order to meet project success. Keywords—project planning, perceived project success, project risk, moderation
Outsourced contracts, buyer-supplier trust, supplier opportunistic behavior and supplier performance in ugandan public procuring and disposing entities (PDEs)
(Journal of Public Procurement, 2021) Ahimbisibwe, Arthur; Muhwezi, Moses; Nangoli, Sudi
This study sought to examine the extent to which outsourced contracts, buyer-supplier trust and supplier opportunistic behavior explain supplier performance in Ugandan Public Procuring and Disposing Entities (PDEs). This study was prompted by reports of long lead times, failure to match specifications, late deliveries, poor quality of services delivered, contract violations, and increased supplier cheating. Cross sectional data from 116 central government PDEs concerning outsourced contracts was collected using a self-administered questionnaire. Hierarchical regression was used to indicate what happens to a model that was developed as part of this research as different predictor variables are introduced. The findings revealed that outsourced contracts, buyer-supplier trust, and supplier opportunistic behavior are significant predictors of supplier performance. The study has both managerial and policy implications which are discussed in this paper.
Project Communication and Perceived Project Performance: The Mediating Influence of Individual Commitment in Uganda’s Citizenship Projects
(ORSEA JOURNAL, 2017) Ahimbisibwe, Arthur; Nangoli, Sudi; Tusiime, Wilson
This paper examines the mediating influence of individual commitment on the relationship between project communication and perceived project performance. Many citizenship projects frequently fail to deliver on time, budget, specifications, and quality or do not deliver value to the public. This could be attributed to ineffective project communication and lack of individual commitment. Despite previous research contributions, no existing studies have investigated the mediating influence of individual commitment on this relationship. Thus, empirical research to corroborate these claims in this area remains anecdotal and scanty. Based on a cross sectional data set from 322 citizenship project stakeholders in Uganda used to validate the theoretical model, findings reveal that individual commitment elements (affectivity, normative and continuance) significantly mediate the relationship between project communication and perceived project performance. The results also suggest that affectivity and normative commitment have a stronger influence towards perceived project performance than continuance commitment. Theoretical and practical implications are also discussed.
Project Communication, Individual Commitment, Social Networks, and Perceived Project Performance
(Journal of African Business, 2012) Ahimbisibwe, Arthur; Nangoli, Sudi
This research examines the role of project communication, individual commitment, and social networks in explaining perceived project performance. Despite the increased involvement of commercial banks in citizenship projects in Uganda, anecdotal evidence reveals that over 70% of citizenship projects fall short of the expected quality, fail to boost bank awareness, are cost overrun, and are completed behind schedule. Based on data from 121 citizenship projects conducted by 16 commercial banks in Uganda, findings revealed that project communication, individual commitment, and social networks are significant predictors of perceived project performance. This study has managerial implications, which are presented in this article.
Regulation of Boda Boda Operators and Road Accident Reduction in Uganda: A Case of Kampala City Council Authority
(ORSEA JOURNAL, 2017) Bagenda, Bonny; Ahimbisibwe, Arthur; Tusiime, Wilson; Moya, Musa
Motorcycle transport commonly referred to as Boda Boda is a popular means of transport in Uganda. It is cheap compared to the other forms of motorized transport, easy to maneuver where roads are impassable to motor vehicles, and carries passengers from doorto- door because the culture of walking is not typical to many Ugandans. Despite benefits offered by boda boda transport, it has proved difficult for the government to regulate the industry. There is some operational discipline provided by the associations to which majority of boda boda operators belong though most of them have only a local jurisdiction. Lack of clear regulations in the boda boda industry as well as weak enforcement of these regulations is threatening the safety of passengers and riders as well. Despite several attempts to streamline the industry, the exercise has not been successful, making boda boda account for a significant number of fatal road accidents across the country. The purpose of the study was to investigate the regulation of boda boda operations in Kampala City Council Authority (KCCA) and its impact on road accident reduction. A quantitative research approach and cross-sectional survey were adopted. Data were collected using a self- administered questionnaire. Implications for both theory and practice are discussed, especially suggestions for government in formulation of policies and regulations that govern boda boda operations.
Relationship between Perceived Factors for Effective Logistics and Customer Satisfaction: A Case of Tanzania’s Telecommunication Industry
(ORSEA JOURNAL, 2018) Tusiime, Wilson; Ahimbisibwe, Arthur; Nangoli, Sudi
In recent years, the Tanzania’s telecommunication industry has been seen as one of the most evolving industries in the country due to dynamic technological changes leading to increased levels of competition, thereby forcing customers to constantly switch to different companies though there are numerous logistical services provided by the companies. This research investigates the relationship between the perceived factors for effective logistics and customer satisfaction in Tanzania’s telecommunication industry. Case study design methodology was used whereby primary data were obtained through observation, in-depth and documentary review. Findings revealed a coefficient correlation of 0.625, thus, it was concluded that there is a strong relationship between perceived factors for effective logistics and customer satisfaction. It is recommended that for telecommunication companies to effectively serve their customers and survive in this highly competitive market, there is need for the telecom companies to put a lot of emphasis on perceived factors for effective logistics. Managerial and theoretical implications are also well discussed in this article.
Social networks: a strategy for enhancing project-stakeholder commitment
(Journal of Strategy and Management, 2013) Nangoli, Sudi; Ahimbisibwe, Arthur; Namagembe, Sheila; Bashir, Hassan
The purpose of this paper is to examine the human dimension of project management by establishing the extent to which social networks influence the commitment of project stakeholders. Up to date, project managers still identify inadequate stakeholder commitment to project undertakings as a key antecedent of project failure and so efforts aimed at addressing this challenge are highly valued. The paper therefore explores the use of social networks as one of the possible strategies to enhance project-stakeholder commitment. Design/methodology/approach – The paper adopts a quantitative, cross-sectional study design. Based on responses from 172 project stakeholders who took part in a sample of 92 citizenship projects conducted by major commercial banks in Uganda, hierarchical regression was used to indicate what happens to a model as different predictor variables are introduced The use of specific type of projects minimizes bias in results due to the unique nature of specific projects hence enhances reliability of results. Findings – The results from statistical analysis reveal that social network elements (network transitivity and network degree) are significant predictors of project stakeholder commitment. The results also suggest that network transitivity is a better significant predictor of project-stakeholder commitment than network degree Practical implications – Project-stakeholder commitment has beenwidely studied in relation to project performance and the study makes a number of contributions to the theory and study of projects. First and foremost, the paper studied project social networks and project-stakeholder commitment in citizenship projects in commercial banks in Uganda which is a developing country. The study therefore contributes to an understanding of project social networks and project-stakeholder commitment in citizenship projects of commercial banks in a developing country. The implication of the findings is that it provides a different view point of understanding the aspects that affect project commitment. A lot of focus has been placed on improving project performance in Uganda, but none has specifically focussed on building projectstakeholder commitment through the use of project social networks. Originality/value – Earlier attempts to investigate the impact of social networks on commitment in projects did not study commitment among individuals. Also, no previous empirical study in less developed countries has given special attention to the effect of social networks on project-stakeholder commitment especially in the domain of citizenship projects which have gained a lot of momentum around the globe. The study results indicate that getting concerned with the nature of social networks the project creates and the means it uses to maintain such networks has implications for projectstakeholder commitment.
Supply Chain Visibility, Supply Chain Velocity, Supply Chain Alignment and Humanitarian Supply Chain Relief Agility
(European Journal of Logistics, Purchasing and Supply Chain Management, 2016) Ahimbisibwe, Arthur; Ssebulime, Ronald; Tumuhairwe, Ronald; Tusiime, Wilson
The research aimed at examining the relationships between supply chain visibility, supply chain velocity, supply chain alignment and supply chain relief agility using a case of humanitarian agencies in responding to Bududa Land Slide disasters in Eastern Uganda. The study was motivated by the fact that although several humanitarian agencies responded by delivering aid to those in need during the aftermath of Bududa landslides in 2010, their humanitarian supply chains were not fast and agile enough to respond to the sudden onset disaster. A cross sectional data was collected from a sample of sixteen (16) humanitarian agencies that were involved in responding to landslide disasters in Bududa district in Eastern Uganda region. A total of 135 usable questionnaires were collected which were used for data analysis. The results indicate significant positive relationships between supply chain visibility, supply chain velocity, supply chain alignment and supply chain relief agility. Findings also revealed that supply chain visibility and supply chain alignment are significant predictors of humanitarian supply chain relief agility. The study has both practical and theoretical implications which are discussed.
Using the Behavioural Factors to explain Perceived Project Performance of Ugandan Citizenship Projects: A Multivariate Analysis
(International Journal of Business and Social Science, 2012) Ahimbisibwe, Arthur; Nangoli, Sudi
The purpose of this paper was to develop and validate a causal modal of behavioural factors that explains perceived project performance of Ugandan Citizenship projects. Although numerous classical studies are reported in various contexts involving project communication, individual commitment, social networks and perceived project performance, no existing study focuses on how these four domains are linked together. Based on literature review, a theoretical model and 15 hypotheses were developed. A cross sectional data from a survey of 322 project staff of all 121 citizenship projects conducted by all 16 commercial banks in Uganda was used to validate the model. The results of Structural Equation Modelling support 11 of the 15 hypotheses and reveal that project communication does not influence perceived project performance directly but it influences it through the mediation of social networks and continuance commitment. Surprisingly, the study data did not support path coefficients between the other two individual commitment elements (affectivity and normative) and perceived project performance. Although these constructs are robust and sufficiently represent the behavioural aspects, the multidimensional nature of behavioural practises in perceived project performance can be investigated further. The individual commitment elements were expected to positively influence perceived project performance but did not. The use of case studies and additional surveys in future research might help to explain this surprising paradox. Further, since the future of project management practises go through evolution, additional ‘soft’ factors may be incorporated into the four domain causal model. The study results suggest that the social network elements fully mediate the relationship between project communication and perceived project performance. This implies that the corporate managers of citizenship projects need to develop strategies to create social networks with their stakeholders in order to increase perceived project performance.
