The rapid growth of e-commerce in Sri Lanka has resulted in an increase in the number of e- customers and e-retailers. To sustain this growth, e-commerce players must differentiate their offerings and operations to meet the evolving needs of customers, with customer satisfaction being a crucial factor in achieving a competitive advantage. Delivery logistics plays a critical role in ensuring customer satisfaction. A systematic literature review, following the PRISMA framework, identified the most impactful delivery logistics factors on customer satisfaction as delivery time, cost, and quality. Building upon this, the study utilized the mental accounting theory (MAT) to develop a conceptual framework. The objective of this study was to examine the relationship between delivery logistics factors and customer satisfaction and to explore the moderating effect of geographical variations and product categories on this relationship. Data was collected from a sample of 272 respondents living in rural and urban areas, using a structured questionnaire. The data were analyzed using partial least squares structural equation modelling (PLS-SEM). The findings suggest that delivery logistics factors have a positive impact on customer satisfaction and that the geographical location of customers, and the product category moderate this relationship. Specifically, for econsumers from rural areas, delivery cost was found to be a significant predictor of customer satisfaction. Furthermore, delivery logistics factors positively influenced customer satisfaction for shopping and special goods, but not for convenience goods. Overall, this study emphasizes the importance of delivery logistics in e-commerce, particularly in a developing country like Sri Lanka. It provides valuable insights for e-commerce players to enhance their operations and offerings, meet customers' needs, and improve their competitiveness.
Determinants that Drive the Behavioural Intention of Employees in the IT industry to Use CI/CD Framework: A Study based on Sri Lankan IT Companies
(Department of Industrial Management, Faculty of Science, University of Kelaniya Sri Lanka, 2023) Karunarathna, Chamindu; Jayasinghe, Shan; Wijayanayaka, W. M. J. I.
Continuous Integration and Continuous Delivery (CI/CD) is an Agile-based software development methodology becoming increasingly popular in the software development industry due to its ability to automate the software delivery process, reduce the time to market, and enhance software quality. However, despite the growing interest in CI/CD adoption, many organizations have not achieved full success in implementing and utilizing the CI/CD workflow. To address this gap, this study aimed to identify the factors that drive the behavioural intention of IT employees to use the CI/CD workflow: based on the Sri Lankan context. A systematic literature review using the PRISMA framework identified the Technology Acceptance Model and the Unified Theory of Acceptance and Use of Technology models as the most widely used and accepted models for understanding technology adoption. Therefore, TAM, UTAUT and past literature were used to develop the conceptual framework. The variables in this research model were measured through questionnaires with nominal and five- point Likert scales and close-ended questions, which were completed by the IT employees in Sri Lanka. Data cleaning and demographic data analysis were conducted using IBM SPSS 21, and preliminary data analysis was performed using PLS-SEM (SmartPLS 4). The study found that Performance expectancy is the most significant factor determining IT employees' behavioural intention to use CI/CD workflow. Therefore, the study concluded that organizations and management should focus more on enhancing employees' performance expectancy to adopt CI/CD workflow successfully.
