This study aims to examine the effect of supplier monitoring on procurement performance in the Tanzanian public sector, as well as how contract management difficulty moderates the effect of supplier monitoring on procurement performance.

In this paper cross-sectional data were collected from 179 Tanzanian public procuring organizations using a structured survey questionnaire. Confirmatory factor analysis (CFA) and the PROCESS macro were used to analyse the collected data.

Supplier monitoring has a positive and significant relationship with procurement performance in terms of cost reduction, lead times and buyer satisfaction. Furthermore, contract management difficulty has a negative moderating effect on the relationships between supplier monitoring and procurement performance dimensions.

Because public procurement is governed by laws and procedures, generalization of results should be done with caution. This is because the study is currently limited to Tanzanian public procurement. Apart from contract management difficulty, future research can look at other factors that may be needed to moderate the link between supplier monitoring and procurement performance.

Procurement practitioners must monitor major suppliers’ timeliness, product quality and order accuracy in order to improve procurement performance. Furthermore, proper contract management is required, which necessitates effectively reinforcing procurement contract managers’ responsibilities and providing contract management training for practitioners in order to control anomalies when suppliers and contracts are involved.

By adding a moderating variable, the study adds to the literature on supplier monitoring in public procurement and the on-going debate on supplier monitoring and performance.

Over time, the concept of word of mouth (WOM) has spread beyond marketing into other disciplines. This is because WOM is important in decision-making at both the individual and organisational levels. Also, people are more likely to trust recommendations from their peers than those from companies. Therefore, the purpose of this study is to investigate the perceived usefulness of WOM messages for small and medium-sized enterprise (SME) suppliers in participating in Tanzanian public procurement opportunities.

The study collected cross-sectional data from 214 SME suppliers who supply common use items to public procuring organisations in Dodoma City, Tanzania. Structural equation modelling was used to test the direct relationships between study variables, and Hayes' PROCESS macro was used to test for the indirect effect of WOM message delivery on WOM attributes and the perceived usefulness of WOM.

WOM attributes that include expertise differential, perceptual homophily, and trustworthiness are related to the perceived usefulness of WOM. Also, WOM message delivery mediates the relationship between the WOM attributes and the perceived usefulness of WOM in enhancing public procurement participation. Therefore, the study's findings revealed that WOM is applicable in the public procurement context, under which public buyers act as senders and suppliers act as receivers. The latter finds out about public procurement opportunities and responds to them, while the former gives suppliers whatever information they need to respond to public procurement tenders that have been advertised.

Because the study was cross-sectional, it was difficult to determine whether the opinions gathered over time remained consistent. Furthermore, only suppliers who are parties to framework contracts under Government Procurement Services Agency were included in the study. Therefore, the sample was limited to only suppliers supplying common use items to various public organisations in Dodoma City, Tanzania.

This paper integrates the concept of WOM from the marketing discipline and public procurement. As a result, the study adds to the understanding of the use of information transmission in terms of the contribution of WOM messages from public buyers to suppliers to enhance small and medium enterprises' participation in public procurement opportunities.

This study aims to examine the role of supplier selection and supplier monitoring in public procurement efficiency in terms of cost reduction in Tanzania.

A structured questionnaire was used to collect cross-sectional survey data from 179 public procuring entities in Tanzania. Structural equation modelling (SEM) was used to analyse the collected data.

The findings revealed that supplier selection and supplier monitoring are positive and significant predictors of public procurement efficiency in terms of cost reduction.

This study was conducted in Tanzanian public procurement contexts, so generalisations should be made with caution. Also, this study collected cross-sectional data; other studies may consider longitudinal data.

This study provides procurement practitioners with insights into selecting the proper suppliers and embracing supplier monitoring to achieve procurement efficiency in terms of cost reduction.

This study examines the effects of supplier selection and supplier monitoring on procurement cost reduction as a measure of public procurement efficiency in the Tanzanian context. Consequently, it provides empirical evidence of supplier management practices in the public procurement context.

While empirical studies establish the importance of procurement planning in achieving value for money (VfM) in procurement, there is scant evidence demonstrating a link between procurement planning and procurement regulatory compliance, and thus VfM. As a result, this study examined how procurement regulatory compliance can be applied when procurement practitioners in Tanzania seek to maximize VfM through procurement planning.

A cross-sectional research design was adopted from which data were collected once through a structured questionnaire. The structural equation modeling (SEM) and Hayes' PROCESS macro test for mediation analysis were used to analyze the collected data.

Procurement planning has a significant and positive relationship with procurement regulatory compliance (ß = 0.491, p < 0.001). Procurement regulatory compliance has a significant and positive relationship with VfM in procurement (ß = 0.586, p < 0.001). Results also show that procurement planning is a significant positive predictor of VfM (ß = 0.257, p = 0.005). Furthermore, the bootstrapping confidence intervals revealed that procurement regulatory compliance significantly mediates the relationship between procurement planning and VfM in procurement.

Although the study was able to accomplish its overall objective, it is limited in terms of the geographical setting under which the study was conducted. Hence, the generalization of research results should be made with caution as each country has specific public procurement laws and regulations governing the conduct of procurement activities in the public sector.

The study contributes to the growing debate on achieving VfM in procurement activities. The study adds to the literature on public procurement by establishing the mediation effect of procurement regulatory compliance on the quest toward achieving VfM in public procurement.

This research aims to explore the concept of green dynamic capabilities, which can facilitate the adoption of green technological innovations for the purpose of enhancing brand sustainability. Specifically, the study seeks to investigate the mediating role of green technological innovations in the relationship between green dynamic capabilities and brand sustainability.

To achieve this aim, the study employed partial least squares structural equation modeling (PLS-SEM) and surveyed 316 managers of manufacturing enterprises.

The results showed that all relationships tested were positive and significant, and green technological innovation was found to be a significant mediator in the relationship between green dynamic capabilities and brand sustainability.

By adding a mediating variable (green technological innovations), this study adds to the literature on sustainability as well as contributes to the on-going debate on how manufacturing firms can be related to environmental issues in their productions.

The main purpose of this study is to investigate the mediating role of innovation culture in the relationship between knowledge-based dynamic capabilities and innovation performance of small enterprises in Tanzania.

This study is cross-sectional and data collected through structured questionnaire were analyzed using PLS-SEM.

The findings revealed that dimensions of knowledge-based dynamic capabilities significantly influence innovation culture and innovation culture significantly influence the innovation performance. Finally, innovation culture is a significant mediator of the relationship.

The study contributes to the understanding that owners of small businesses must create conducive environments for the development of an innovation culture by improving knowledge acquisition, generation and combination for better innovation performance outcomes.

Studies done on innovation culture are limited especially in the context of developing countries such as Tanzania where adoption of innovative ideas is considered a slow process due to various factors such as poor management of knowledge resources. Therefore, this study contributes to the body of knowledge by establishing a link between knowledge-based dynamic capabilities and innovation performance through a mediation of innovation culture.

The combination of strategic orientation and digitalization for sustainable competitive advantage among small businesses is still not given much attention in the literature. Therefore, this study aims to understand the influence of strategic orientation on sustainable competitive advantage while mediating the relationship with digitalization.

This study used a cross-sectional design. This design helped collect data from 234 small businesses in Arusha city, Tanzania. Since the study used latent variables, structural equation modeling (SEM) was used to analyze relationships and conduct confirmatory factor analysis. Through bootstrapping confidence intervals, Hayes's Process was also used to test how digitalization mediates the relationship between strategic orientations and sustainable competitive advantage.

The strategic orientation attributes that include market orientation, entrepreneurial orientation and learning orientation were positively and significantly related to digitalization. Furthermore, the results on digitalization and sustainable competitive advantage show a significant positive relationship. Finally, digitalization was analyzed to mediate the relationship between strategic orientation, market orientation, entrepreneurial orientation, learning orientation and sustainable competitive advantage. Hence, all hypotheses were supported.

This study adopted a cross-sectional design that helped to capture the quantitative information. In addition, the current study is limited to Tanzania's small businesses; thus, the findings cannot assure generalization of the conclusion to other countries because of the differences in social, cultural and technology across countries.

This study integrates the concepts of strategic orientation from the strategic management discipline and digitalization from a technology perspective. As a result, the study adds new knowledge about combining two aspects and determining whether they add value in terms of providing a sustainable competitive advantage. This knowledge comes from digitalization, which acts as a mediator between strategic orientation dimensions and a sustainable competitive advantage.

This study aims to analyze the mediating effect of brand love (BRL) on the relationship between service quality and brand addiction (BRA) among Islamic banks. Past studies have noted that customer satisfaction as the primary means of studying customer behaviour needs to be reconsidered because even satisfied customer switch brands, and the dissatisfied customer have repurchasing intentions. Therefore, considering BRL and BRA can be a new way of studying customer behaviour in Islamic banking.

This study used a structured questionnaire administered to 380 customers of Islamic banks. The study used structural equation modelling and Process Macro test in the analysis.

The empirical findings of this study suggest that service quality is positively and significantly related to BRL and that BRL positively and significantly relates to BRA. Furthermore, the findings indicate that BRL mediates the relationship between service quality and BRA.

The findings of this study have revealed that the triangular theory of love and expectation-confirmation theory can be combined to explain the relationship between service quality and loving relationships among customers of Islamic banks.

The study provides ways in which service providers can use service qualities to manage BRL and addiction. Based on the positive and significant relationships, managers of Islamic banks can build service qualities that are vital for creating BRL and BRA.

The link between service quality, BRL and BRA is not adequately established, especially in Islamic banking. This is important to be established because studying consumer psychology is currently considered a vital strategy for customer repurchasing and switching barriers in the modern banking business. Furthermore, integrating two theories, the triangular theory of love and expectation-confirmation theory, provide a new way of combining two theoretical aspects from different disciplines.

Consumer psychology research has established the importance of customer satisfaction as a determinant of customer repurchasing intention. Nonetheless, even satisfied customers switch brands. Also, even dissatisfied customers have repurchasing intentions. This means that customer repurchasing behaviour is extremely difficult to predict, necessitating additional research to identify additional factors that can help organizations better understand the methods to predict customer repurchasing intention. To fill this knowledge gap, this study examined the mediating effects of brand love (BL) and positive word of mouth (PWOM) on psychological contract fulfilment (PCF) and customer repurchasing intentions.

This is a cross-sectional study. The study used structural equation modelling (SEM) to analyse relationships from a sample size of 400 beauty salon customers. Also, a process macro mediation test was used to analyse the mediating effects of BL and PWOM on the relationship between PCF and customer repurchase intentions.

The findings indicate that transactional and relational psychological contracts have a positive and significant relationship with BL and PWOM. As well, BL and PWOM positively and significantly influence customer repurchase intentions. Finally, the findings indicate that BL and PWOM mediate the relationship between psychological contract fulfilment and customer repurchase intentions.

This survey sampled beauty salons solely. Given that each type of organization may have a unique way of fulfilling psychological contracts, future studies may include more categories such as restaurants and craftsmanship to broaden the sample. Additionally, this study utilized female beauty salons. Therefore, future research could include salons that cater to women and men to boost the sample's generalizability. Finally, this study concluded that BL and positive recommendations are the most effective variables for resolving consumer satisfaction challenges. However, additional factors can probably amplify this fact by focusing on additional elements to broaden the arguments.

Past studies have extensively covered customer repurchasing intention in relation to customer satisfaction. However, it was noted that even some satisfied customers could switch to other brands, and those who were dissatisfied could repurchase the brand. Given that little is known about how other factors than customer satisfaction can affect repurchasing intentions, this study examines the mediating effects of BL and PWOM on PCF and customer repurchase intentions.
