This study investigates whether Savings and Credit Co-operatives’ (SACCOS) services such as loans, savings and training improve household livelihood outcomes.

The study employed a quasi-experimental design. Six SACCOS were purposively selected in four districts of Mwanza and Tabora regions in Tanzania. A sample of 500 respondents was randomly selected of whom 200 were SACCOS’ members and 300 were non-members. A questionnaire and a key informant interview guide were used to collect quantitative and qualitative data respectively. Propensity Score Matching (PSM) was used to analyse the quantitative data whereas qualitative data was subjected to thematic analysis.

The results indicate that SACCOS’ services had significantly impacted on the household livelihood outcomes in terms of maize yields, household assets, savings, food expenditures and non-food expenditures.

This study was conducted in two regions of Tanzania using six SACCOS. Similar studies can be conducted in a larger area of Tanzania by capturing more than six SACCOS. In addition, the study focused on the rural areas of Tanzania. The future studies can be carried out in urban areas or both urban and rural areas of Tanzania.

Local leaders, SACCOS’ leaders and other stakeholders in the study area should thus mobilise non-members in their areas to join SACCOS. In addition, the Tanzania government should facilitate the formation of new SACCOS and strengthen those already operating in rural areas.

SACCOS provide opportunities for individuals and households in rural areas to converge socially and economically to achieve better results (positive impact on livelihood outcomes), which otherwise could be non-achievable through single household or individual efforts.

Unlike previous studies, this study provides empirical evidence on the impact of SACCOS’ services on livelihood outcomes of SACCOS members in rural areas of Tanzania where abject poverty is widespread and where the majority of SACCOS are found.

This paper aims to examine lean thinking in medical commodities supply chains by considering its applications and success factors. It determines the drivers and wastes of medical commodity supply chain, and the existing lean tools and practices together with their application in the supply chain processes. The paper also examined the challenges and success factors for effective lean application in the medical commodities supply chains.

The study used qualitative approaches, in-depth interviews and focus group discussions with key informants to form the basis for data collection. Through thematic analysis, the collected data were analyzed by developing themes reflecting the objectives of the study.

The main drivers for waste associated with the supply chain were demand management, supplier development, institutional framework and governance. The wastes were observed at the level of inventory, operation costs, transaction costs, delays in terms of service, commodity delivery time and quality. Digitalization, information technology and standardization were the tools for medical supply chain. Poor infrastructure, unreliable internet supply, environmental uncertainty and poor management support were challenges to realizing an effective supply chain.

Although the qualitative approach used in the study provides detailed information, a quantitative study covers a larger sample for generalization.

Capacity building and professionalism should be given a priority because the philosophy of lean focuses on waste removal and continuous improvement, which highly depends on the quality of human resource (Brito et al., 2020). Limited human resource capabilities in supply chain management will, therefore, result into poor operational efficiency, which are wasted. Moreover, systems interoperability is key waste minimization and, therefore, demands interventions.

The government under the Ministry of Health and other key sector ministries such as local and regional governments should better understand the role of the waste drivers and adopt system-wide reforms to support improvements to remove waste in the medical supply chain. For example, the current institutional framework creates an administrative block and hence leads to wastes. This bureaucratic procedure should be removed to minimize wastes along the chain.

This study is among the first studies to determine applicability and implementation of lean in a resource-constrained context. The paper identifies contextual factors for lean implementation. This paper focused on a holistic view of the entire supply chains to enhance a well-functioning supply chain in delivering health commodities.
