    Agile enablers and outcomes: empirical validation of agile manufacturing model in developing countries context-Ugandan SME’s experience
    (International Journal of Technology and Management, 2020-12-01) Nagaaba, Nickson
    This article focuses on the extent to which agile mnufaccturing enablers contribute to factory performance of small and medium enterterprises enaged in manufacturing business. This study was aimed at establishing the influence of technological adaptive capabilities, efficient transaction processes and systems and organizational and politicl ties on factcory performance. A questionnaire based survey was conducted in Western region of uganda and Kampala Capital City with a population 148 SMEs engaged in manufacturing. A sample of 129 SMEs was selected and data were successfully and effectively collected from a 103 SMEs. Care was taken to ensure reliability and validity of data. hypothesized relations were tested usins correlations and hierarchical regression. Result indicate that organizational and political ties and efficient transaction processes appear as most important agile enablers because they significantly influence the level of factory performance. Technological adaptive ability appear not to give advantage to SMEs in improving factory performance. The findings add an important aspect of involving politics in ties and alliances in fostering factory performance. In addition more insight was provided on how internalization can provide a more efficient mode of manufacturing that further enhances factory performance. The study shades light of the more robust agile manufacturing model that mangers of SMEs should embrace to remain competitive.

    Agile manufacturing and performance of small and medium factories in Uganda
    (Global Scientific Journals (GSJ), 2021-08-08) Nagaaba, Nickson
    A framework was developed to examine the agile manufacturing and performance of small and medium factories in Uganda. Three hypotheses derived from this framework were tested on a sample of 103 factories located in Kampala Capital City and western Uganda, as the largest industrial hubs in the country. Hierarchical regression analysis was used to exam the strength of relationship. Findings suggest that small and medium factories that adopt agile manufacturing have improved their performance. The study indicates that factories that have successfully benefited from agile manufacturing emphasize more of process and information integration. Although the other two agile metrics were not pronounced as very significant (Customer sensitivity and collaborative strategies) in this particular context, appropriate collaborative mix and differentiation strategies are suggested.

    Assessing enabling competence of leagile manufacturing model and its impact on performance of small and medium factories in Uganda
    (American Journal of Operations Research, 2022-06) Nagaaba, Nickson
    Purpose: Leagile manufacturing is one of the time-based manufacturing practices used to improve factory performance. It is a practice that combines initiatives of Lean and agile manufacturing under certain enabling competences. Therefore, the purpose of this study is investigate the combinative nature of time-based manufacturing practices under unique enabling competences and their impact on performance of factories in Uganda. Methodology: Firstly, the underlying factor structure of competences and time-based manufacturing was examined was conducted using Principal Component Analysis (PCA). Enabling competences and time-base manufacturing practices were modelled and validated for each using confirmatory factor analysis, particularly composite reliability, average variance extracted and convergent validity. A fully fledged structural equation model was used to test the impact of leagile manufacturing on performance of factories. Findings: The study results revealed that time-based manufacturing of lean, and leagile are related but differ, in terms of their enabling competences and philosophical orientation. The findings also revealed that when small and medium factories in Uganda adopt leagile practice, they are likely not improve their performance. This is perhaps due to the fact that small and medium factories have inadequate resources. Practical Implications: The study findings shed more insights on the factors that enable adoption and implementation of time-based manufacturing practices. The extent to which these competences are orchestrated determines the benefits derived from the time-based manufacturing practices. In addition, small and medium enterprises should keenly make a choice on the appropriate practices that purposely reduce their lead time and cost of conversion. Originality: This study investigated the combinative nature of time-based manufacturing practices under unique enabling competences and their impact on performance of factories in Uganda. It is among the few studies that provide evidence on the leagile model anchored in the appropriate enabling competences in the context of developing countries. The empirical survey was done on small and medium factories to validate a leagile manufacturing model and tested its impact on factory performance.
