Abstract
Purpose
The approach to integrate concepts from different disciplines so as to solve the problems facing smallholder farmers has gained momentum in recent years. However, very little is known about how word-of-mouth (WOM) dimensions can be used in agricultural marketing to explain market participation among smallholder farmers. Therefore, this study investigates the perceived usefulness of WOM in explaining smallholder farmers’ market participation.
Design/methodology/approach
The cross-sectional design was carried out to survey a sample of 467 smallholder farmers. This study used partial least squares structural equation modelling (PLS-SEM) in SmartPLS 4 to test hypotheses.
Findings
The results revealed that WOM dimensions such as expertise differential, strong tie and trustworthiness among smallholder farmers significantly influence the WOM message delivery. Likewise, the findings suggest that WOM message delivery significantly influences market participation among smallholder farmers. Finally, it was revealed that WOM message delivery significantly mediates the relationship between WOM dimensions and market participation.
Practical implications
This study provides useful insights to smallholder farmers on how to use WOM dimensions to enhance more market participation in formal markets, especially through proper WOM message delivery.
Originality/value
The current study solves the problem of information asymmetry among smallholder farmers through WOM. It is perhaps the first study to establish the link between WOM dimensions and market participation among smallholder farmers in the context of developing countries.

Abstract
Purpose
With increasing concerns regarding the performance of public procurement, especially concerning timely delivery, this study aims to investigate the predictive role of sustainable supplier selection (SSS) in enhancing lead-time performance in public procurement, while also examining the moderating effect of relational capability.
Design/methodology/approach
The study collected primary data from 179 accredited public organizations in Tanzania through structured questionnaires and used partial least squares structural equation modeling for data analysis.
Findings
The results reveal that SSS and relational capability influence lead-time performance in public procurement. Regarding the moderating effect of relational capability, the study establishes that relational capability strengthens the influence of SSS on lead-time performance. Therefore, based on the collected data from surveyed public organizations, relational capability positively moderates the relationship between SSS and lead-time performance in public procurement.
Social implications
The study offer valuable implications for public procurement practitioners, academics and other stakeholders. Public organizations should consider contemplate integrating sustainability aspects into supplier selection processes. Furthermore, the study contributes to advancing efforts toward achieving sustainable development goals (i.e. SDG12) within Tanzania, particularly by advocating for sustainable public procurement practices aligned with national policies and priorities.
Originality/value
This study not only enhances the understanding of public procurement performance by investigating lead-time improvement, incorporating considerations of SSS and relational capability, but it also offers empirical evidence of the moderating role of relational capability within the unexplored Tanzanian context.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Originality/value
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.

Abstract
Purpose
This study aims to examine the influence of procedural capabilities for public procurement participation on small and medium enterprises’ (SMEs) sales performance in Tanzania. Also, the study establishes the interaction effect of internet marketing capabilities on the relationship between procedural capabilities and sales performance.
Design/methodology/approach
The authors conducted confirmatory factor analysis and PROCESS macro for simple interaction analysis to analyse cross-sectional data that were obtained through questionnaire from surveyed SMEs’ managers. The included SMEs are those that are involved in supplying goods, services and works to public entities in Dodoma, Tanzania.
Findings
The findings reveal that procedural capabilities for participation in public procurement enhance SMEs to improve sales performance. Also, there is a significant and positive relationship between internet marketing capabilities and sales performance. Lastly, internet marketing capabilities strengthen the relationship between procedural capabilities and sales performance.
Social implications
This study is a wake-up call to SMEs to better comprehend public procurement procedures and e-business practices to use the available public procurement opportunities. It is argued that SMEs should invest in technology to market their businesses through social media and online platforms. According to the study, SMEs may benefit from improving their sales performance by fully utilising their internet marketing capabilities and participating in public procurement opportunities.
Originality/value
This study adds to the two main streams of literature that emphasise harnessing public procurement opportunities for SMEs (through public procurement participation) and leveraging internet marketing capabilities for SMEs to improve their sales performance.

Abstract
Purpose
The study investigates the effect of behavioural uncertainty on the environmental sustainability of restaurant businesses in Tanzania. Also, the study examines the moderating role of purchasing technical knowledge on the main relationship between the study variables.
Design/methodology/approach
The quantitative approach was used and cross-sectional data were collected at a specific time from restaurant businesses in Dodoma, Tanzania. The PROCESS macro was used to analyse the relationships between behavioural uncertainty, purchasing technical knowledge and environmental sustainability.
Findings
Behavioural uncertainty has a significant and negative effect on the environmental sustainability of restaurant businesses. Purchasing technical knowledge, on the other hand, has a positive and significant effect on the environmental sustainability of restaurant businesses. Finally, purchasing technical knowledge has a positive and significant moderating effect on the relationship between behavioural uncertainty and environmental sustainability such that the negative effect of behavioural uncertainty is reduced with increasing purchasing technical knowledge.
Research limitations/implications
This study considers purchasing skills in terms of purchasing technical knowledge as a moderating variable; hence, other studies may take into account other moderating variables to extend this study. Also, the study considered only environmental sustainability and hence is limited in terms of other dimensions of sustainability and provide an avenue for further research in social and economic sustainability.
Practical implications
Since purchasing technical knowledge reduces the negative effect of behavioural uncertainty on the relationship with environmental sustainability, restaurant managers should be encouraged to improve their purchasing technical knowledge by attending short- and long-term training on purchasing functions in the restaurant industry.
Social implications
The social implications of the investigated link between behavioural uncertainty, purchasing technical knowledge and environmental sustainability in the restaurant industry include raising awareness, promoting sustainable practises and fostering an environmentally responsible culture. By addressing behavioural uncertainty, leveraging purchasing technical knowledge and embracing sustainability the industry can contribute to a more environmentally conscious society.
Originality/value
By providing empirical evidence from Tanzania, the study extends literature on examining the environmental sustainability of restaurant businesses. The study also establishes the interaction effect of purchasing technical knowledge as an important skill in reducing the negative effect of behavioural uncertainty on enhancing environmental sustainability in restaurant businesses.

Abstract
Purpose
Despite the fact that students in higher education contributes significantly to the number of professionals, little has been done to incorporate the students’ perspectives on the status of procurement and supply professions in Tanzania. This study examined the challenges confronting the procurement and supply professions from the perspective of future procurement professionals enrolled in Tanzanian higher education.
Design/methodology/approach
A cross-sectional design was used to collect data from undergraduate students majoring in procurement and supply chain management in Tanzanian higher education using a structured questionnaire.
Findings
The findings revealed that the challenges affecting the procurement and supply professions were buyer- and supplier-related challenges as perceived by Tanzanian higher education students.
Research limitations/implications
The study's findings should be generalized with caution because the findings represent the perspectives of Tanzanian procurement and supply undergraduate business students. Furthermore, the included sample of procurement and supply undergraduates cannot represent all students' perceptions; thus, other studies may broaden the sample by including the opinions of other higher education students.
Originality/value
This is the first study that looks at how students in higher education institutions, who are considered future procurement and supply professionals, perceive the challenges of the procurement and supply professions in Tanzania.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Practical implications
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.
Originality/value
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.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Originality/value
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 analyzes the mediating effect of purchasing efficiency on the relationship between purchasing analytical skills and restaurant performance.
Abstract
Purpose
This study analyzes the mediating effect of purchasing efficiency on the relationship between purchasing analytical skills and restaurant performance.
Design/methodology/approach
A structured questionnaire was used to collect data from 169 restaurant managers in Dodoma, Tanzania. The collected data were analyzed by using partial least squares structural equation modeling (PLS-SEM).
Findings
The results established the direct and indirect effects of purchasing analytical skills on restaurant performance. Specifically, purchasing analytical skills have positive and significant effects on restaurant performance and purchasing efficiency. Also, purchasing efficiency significantly mediates the effect of purchasing analytical skills on restaurant performance. Since purchasing analytical skills significantly influence restaurant performance, and the mediating effect of purchasing efficiency is significant, the study establishes and confirms the partial mediation effect of purchasing efficiency.
Research limitations/implications
The current study solely focused on purchasing analytical skills. Future studies may examine other types of purchasing skills (technical and managerial skills) to expand the study's findings. Furthermore, different mediating variables can be used to study the indirect effect of purchasing analytical skills on restaurant performance.
Originality/value
This study presents empirical evidence from Tanzania, an emerging economy, on the link between purchasing analytical skills and restaurant performance. It also contributes to the body of knowledge by studying the mediating effect of purchasing efficiency in the hypothesized relationship.
