    Buyer-Supplier Integration and Logistics Performance in Health Care Facilities in Tanzania
    (2015) Salema, Gladness; Buvik, Arnt
    Purpose This research concerns logistics performance in public purchasing relationships, and explores the effect of buyer-supplier integration on supplier logistics performance. The research focuses in particular on purchasing centralization in health care facilities, and examine whether centralization of purchasing decision control exercised by the health authorities will influence the effect of buyer-supplier integration on supplier logistics performances at the firm level in health care facilities. Design/methodology/approach This research is based on basic organization theory, inter-organizational theory, and supply chain management literature, and examines the combined effect of purchasing centralization and supplier integration on supplier logistics performance based on survey data from 164 key informants from public health institutions in Tanzania. Findings The analysis reveals that stronger buyer-supplier integration improves supplier logistics performance significantly, and that stronger centralization of purchasing decision control by the health authorities reduces the effect of more extensive buyer supplier integration on supplier logistics performance at the firm level. Research limitations/implications Public health institutions in Tanzania are highly regulated and controlled by public authorities, and this might limit the external validity of this study. Possible effects of opportunistic behaviour among public agents might also influence the outcome of the analyses, and further research in other empirical settings and cultural settings is desirable to test the external validity of the empirical findings. Practical implications The local government should focus more on supporting the individual public health facilities in developing and adapting proper governance mechanisms for their supplier integration, and be aware of the advantages associated to the alignment of independent and local supplier coordination at the institutional level. Social implications Strong bureaucratic decision control and possible opportunistic behaviour among public agents and employee in public medicine institutions might represent a threat against a smooth and effective organization of the medicine supplies in the public sector. Original/value The study provides a valuable theoretical contribution to the supply chain management research. In particular, the combination of significant contributions from basic organization theory, principal-agent theory and supply chain management literature provides a broad and interesting focus on significant antecedents to supplier logistics performance.

    Buyer-supplier integration and logistics performance in healthcare facilities in Tanzania: the moderating effect of centralised decision control
    (Inderscience Enterprises Ltd, 2018) Salema, Gladness; Buvik, Arnt
    This research concerns logistics performance in public purchasing relationships. It examines the effect of buyer-supplier integration on supplier logistics performance. Particularly focuses on purchasing centralisation in healthcare facilities, and examine whether centralisation of decision control exercised by the health authorities influence the effect of buyer-supplier integration on supplier logistics performance. A survey data of 164 informants from public health facilities in Tanzania was used for analysis. It reveals that buyer-supplier integration improves supplier logistics performance significantly and stronger purchasing centralisation reduces the effect of buyer-supplier integration on supplier logistics performance. It provides a broad and interesting focus on significant antecedents to supplier logistics performance. In the future, the government should focus more on supporting the individual public health facilities in developing and adapting proper governance mechanisms for supporting buyer-supplier integration. Further research in other empirical and cultural settings is desirable to test the external validity of these findings.

    THE EFFECT OF OUTPUT MONITORING ON SUPPLIER LOGISTICS PERFORMANCE AND FLEXIBILITY: THE MEDIATING EFFECTS OF BUYERSUPPLIER INTEGRATION IN THE CONTEXT OF ESSENTIAL MEDICINES SUPPLY
    (Business management Review, University of Dar es salaam, 2019) Salema, Gladness
    This paper examines the relationship between output monitoring and supplier performance. It focuses specifically focuses on buyer-supplier exchange relationships in delivering essential medicines in Tanzania, and examines the mediation effects of buyer-supplier integration on supplier’s flexibility and supplier logistics performance. The resource-based view of the firm was used to frame the relationships by considering output monitoring efforts and the buyer-supplier integration as resources aimed to improve performance. A survey data of 111 public-owned health facilities selected randomly after stratifying them into hospitals, health centres and dispensaries was used for final analysis. Structural equation modelling using Smart PLS3 was employed to ascertain the relationship between output monitoring, buyer-supplier integration and supplier logistics performance and flexibility. The research hypotheses focused on both direct and indirect effects. The results revealed that the buyer-supplier integration partially mediates the effects of output monitoring on supplier logistics performance while fully mediating the effects of output monitoring on supplier flexibility. The results of the study imply that buyersupplier integration is critical for multiple dimensions of performance improvement

    The impact of buyer-supplier integration on supplier logistics performance in the hospital sector in Tanzania: the moderation effect of buyers’ cross functional integration
    (Inderscience Enterprises Ltd, 2016) Salema, Gladness; Buvik, Arnt
    Based on the resource-based view (RBV) theory, this study examines the association between buying firms’ cross functional integration, buyer-supplier integration and supplier logistics performance in buyer-supplier relationships. RBV considers these two organisational dimensions of supply chain integration as strategic resources which play an important role in improving logistics performance. This research examines the effects of both intra-firm integration and inter-firm integration on supplier logistics performance with survey data from key informants in the public medicine supply system in Mainland, Tanzania. The unit of analysis is the purchasing relationships between public health facilities and focal suppliers acting as public agents of the national medical stores department (MSD). The empirical analysis is based on data reported by 166 purchasing managers, and demonstrates that stronger buyer-supplier integration improves supplier logistics performance significantly. There is no main effect of the buying firm’s cross functional integration on supplier logistics performance, but more extensive cross functional integration in the buying firms enforces the effect of buyer-supplier integration on supplier logistics performance significantly, and these findings indicate that extensive cross functional integration in the buying firms provides an administrative infrastructure that enhance the effectivity of extensive supplier-buyer integration.

    THE MEDIATION EFFECTS OF BUYER-SUPPLIER INTEGRATION ON THE RELATIONSHIP BETWEEN SUPPLIER-SPECIFIC INVESTMENTS AND SUPPLIER-OPPORTUNISM
    (Business management Review, University of Dar es salaam, 2017) Salema, Gladness
    This research concerns opportunism in a buyer-supplier relationship. Based on transaction cost and relational contracting theories, it examines the mediation effects of the buyer-supplier integration on the relationship between supplier specific investment and opportunism. Mediation effects were estimated using structural equation modelling based on a survey of 111 key informants in the public health facilities in Tanzania. The unit of analysis is the exchange relationship between the Medical Supplies Department (MSD) and the public health facility. The analysis revealed that the buyer-supplier integration negatively mediates the effects of supplier-specific investments on opportunism. In this research, external validity is limited due to a highly regulated environment; as such, more studies should be conducted in different contexts, e.g. culture. The findings from this study have both managerial and theoretical implications. First, purchasing managers should exert more efforts in developing closer relationship with the supplier to mitigate opportunistic behaviours. Second, the government should consider enforcing MSD to make specific investments not only as a means for solving moral hazard problems but also as a means for encouraging and enforcing the development of close co-ordination between the actors. Theoretically, this paper has contributed to the transaction cost theory by indicating that specific investments may not always stand as direct control mechanisms towards opportunism; instead, they can also lead to the development of other relational mechanisms which are effective in mitigating opportunistic behaviours

    The Role of Public Procurement Framework in Stimulating SMEs Innovativeness in Tanzania
    (Orsea, 2014) Salema, Gladness; Kessy, Severine
    This study examined the role of public procurement framework in stimulating SMEs innovativeness. By using a sample of 208 firms and interviews three identified variables, namely, competition, cooperation and specifications of designs were observed to have a positive effect on SMEs’ innovativeness. In other words an increase in these variables in processes of tendering results into an increase in innovation among the SMEs. Despite the observed positive impact of the examined three indicators, respondents highlighted different challenges they encountered in the process of tendering in public institutions. They included difficult conditions like requirement of very high turnover, delay in payments of already delivered services and limited transparency. From findings, it is recommended that governance issues are very important in the process of assuring that public procurement framework will stimulate SMEs’ innovativeness. Specifically, each part should honour the contract agreements. SMEs should be involved in the process of designing work specifications and also public institutions should reduce the unnecessary long procuring process as well as delay in payments.
