![]() Palliative care competence is one of the competencies that must be possessed by generalist nurses. Research establishes a new theoretical foundation for Transaction Cost Economics (TCE) by introducing ICT strength as a new governing structure of TC. The experiment on mediating effect of TC and related factors also made a unique contribution. The study obtained a large explanatory ability by examining all the dimensions of ICT strength, TC, and business performance that have not been studied yet. The study strongly recommends that SMEs reinforce their ICT strengths, especially mobile technology, with applications by minimizing the impact of TC and its related factors as a novel perspective. ICT strength substantially reduces the TC, and TC as a mediating variable makes neither significant effect directly on the business performance nor relationship between ICT Strength and SME business performance. TC did not significantly impact on business performance of SMEs. Uncertainty, asset specificity, bounded rationality, and opportunism negatively impacted on business performance of SMEs, while transaction frequency affected positively. These dimensions negatively impacted the TC and made a significant positive impact on the business performance. The dimension of ICT strength has a significant negative impact on TC-related determinants and assumptions except for transaction frequency, which showed a positive relationship. Partial Least Square - Structural Equation Modelling (PLS-SEM) was used to analyse the data using SmartPLS V3. Pre-tested structural questions were used for data collection. ![]() A sample of 400 manufacturing SMEs was selected from 81,531 SMEs in Sri Lanka by applying the Inverse Square Root Method. The conceptual research model contained independent variable ICT strength and dependent variable business performance of SMEs with a mediator as TC for developing hypotheses and tested on quantitative method. Therefore, this study concerns exploring the effect of ICT strength on TC and the business performance of SMEs in Sri Lanka. SMEs have the possibility to access sufficient information through ICT, and they can safeguard their transaction to improve business performance. Therefore, they suffer the hazard of opportunism and lead to generate Transaction Cost (TC), which discourages firms’ Business Performance. Many scholars highlighted that SMEs do not have sufficient knowledge and information to make rational decisions compared to large firms. The development of the SME sector is a big challenge, and it records a high failure rate. Finally, the study identified two methods that are more suitable in methodologically and technically which have identified by non-robust scholars who deeply addressed all the aspects of the techniques in the determination of minimum sample size for SEM analysis and thus, the prepare recommends these two methods to rectify the issue of the determination of minimum sample size when using SEM in a research project. The paper evaluated the surface mechanism and rules-of-thumb of more than twelve previous methods that contained their own advantages and limitations. The study found that a large number of methods and rule-of-thumbs have been employed by different scholars. The paper collected research articles related to the sample size determination for SEM and review the methods and rules-of-thumb employed by different scholars. Therefore, this paper attempts to make a review of the methods and rule-of-thumbs involved in the determination of sample size at the use of SEM in order to identify more suitable methods. Basic methods and techniques involved in the determination of minimum sample size at the use of Structura l Equation Modeling (SEM) in a research project, is one of the crucial problems faced by researchers since there were some controversy among scholars regarding methods and rule-of-thumbs involved in the determinatio n of minimum sample size when applying Structural Equation Modeling (SEM).
