(Public Library of Science, 2025-02-05) Wijesinghe, U; Mapitiyage, V; Wickramarathne, C; Wickramage, C; Wisenthige, K; Aluthwala, C
Agile software development is immensely popular in the industry, but most teams struggle to sustain its use. Human factors like management support, agile training, agile mindset, and team resilience are often neglected, hindering long-term success. However, research has not explored their underlying mechanisms in depth. Therefore, this study examines if management support impacts the sustained usage of agile methodologies within software development teams. It subsequently investigates the individual and serial mediating effects of agile training, the agile mindset, and team resilience on this relationship. Additionally, it compares the importance and performance of management support, agile training, the agile mindset, and team resilience in infusing agile practices. Finally, it determines these antecedents’ necessity for the enduring success of agile application. Data collected from 391 agile software development professionals using a structured questionnaire. Partial-least-squares structural equation modelling, importance-performance map analysis and necessary condition analysis were used to investigate relationships. The findings underscore the pivotal role of management support in infusing agile practices. Agile training, mindset, and team resilience emerge as critical mediators, with a strong serial mediation effect. While management support is paramount, its practical implementation falls short within teams. All four antecedents are found to be necessary for optimal agile sustainment. Thus, this study significantly advances theoretical understanding by introducing a serial mediation model that elucidates their mechanisms in impacting agile infusion. It extends prior organisational-level findings to the team-level. The study’s quantitative verification of qualitative findings strengthens their generalisability to a broader spectrum of teams. It pioneers in expounding the constructs’ relative importance, performance and necessity, to offer actionable insights for agile practitioners. Finally, it provides methodological guidance to apply importance performance map analysis and necessary condition analysis in agile software development research. Adult

How E-commerce Succeeds: The Role of Information Systems in Boosting Customer Satisfaction
(Institute of Electrical and Electronics Engineers Inc., 2025) Pathirana, S.L; Pathirana, S.J; Boyagoda, G.S.B; Thalagala, S.M.K; Wisenthige, K; Aluthwala, C
The rapid growth of e-commerce has revolutionized consumer behavior, especially among Millennials and Generation Z, who increasingly rely on online platforms for their purchases. This paper shows the impact of information systems success on individual performance outcomes in e-commerce, focusing on the DeLone and McLean information system success model and its three key dimensions: system quality, information quality, and service quality. A quantitative survey method was employed to gather data from e-commerce users in the western province of Sri Lanka, which is an economically developed region where Millennials and Generation Z are highly engaged with international and local e-commerce platforms. The study uses PLS-SEM to identify that system, information, and service quality significantly increase customer satisfaction and thereby improve individual performance in e-commerce. The study will address the significant research gap in Sri Lanka, where the rapid growth of e-commerce has not been adequately studied in terms of the impact of information and individual outcomes

The Influence of Generative AI on work-life balance among female software professionals in Sri Lanka
(Institute of Electrical and Electronics Engineers Inc., 2025) Upeksha, S; Samarasinghe, D.T; Sanochana, M; Samarathunga, S.S; Rajamanthri, L; Samarakkody, T; Aluthwala, C
This study explores the role of generative artificial intelligence on work-life balance among female software professionals in Sri Lanka's software industry. This qualitative study explores the influence of Generative Artificial Intelligence (GenAI) tools on workload, productivity, and overall well-being to show how these technologies uniquely shape professional and personal lives within this demographic group. Data were gathered through semi-structured interviews with 15 female software professionals from various job roles, including software engineers, quality assurance engineers, system engineers, Development and Operations (DevOps) engineers, and project managers. Using thematic analysis, findings disclose that generative AI is mostly utilized for automation, communication and collaboration, creativity and innovation, and decision support, with ChatGPT being the most widely used tool. These tools will enable professionals to streamline the workload, increase efficiency, reduce overtime, and maintain healthy working conditions. The insights of this study yield important implications for employers and government organizations such as the Department of Labor, explicitly pointing out how generative AI can be instrumented to create a favorable work environment. Thus, by applying generative AI solutions, the key stakeholders of the Sri Lankan software industry can create work conditions crucial for the work-life balance of women to enhance organizational performance as well as the work-related well-being of female software professionals.

The Influence of IT Infrastructure and Supply Chain Flexibility on Supply Chain Performance in the Apparel Manufacturing Sector
(Institute of Electrical and Electronics Engineers Inc., 2025) Kulasekara, D; Sandaruwan, D; Ekanayake, T; Perera, A; Wisenthige, K; Aluthwala, C
In a developing country, the apparel manufacturing sector needs to improve their performance, reduce costs, and satisfy the demands of a highly competitive global market. Thus, Supply Chain Management (SCM), particularly the influence of IT Infrastructure (ITI) and Supply Chain Flexibility (SCF) in driving Supply Chain Performance (SCP), focuses on their combine within the Sri Lankan apparel manufacturing sector. These relationships were evaluated using a quantitative research approach, with data gathered from Supply Chain (SC) professionals in apparel manufacturing companies. The study reveals that SCF mediates the relationship between ITI and SCP, indicating the importance of a flexible SC in moving ITI investments into functional performance improvements. Considering the current environment, apparel manufacturers should apply methods that relate ITI capabilities to the SC ability to respond to changing demands. Technological foundation influences SCF, enabling organizations to respond effectively to market demand and operational challenges. Consequently, SCF significantly contributes to SCP by improving flexibility, reducing costs and enhancing customer satisfaction. Some of the practical implication include the usage of advanced IT systems including prophetic analytics and enterprise resource planning tools to enhance SC responsiveness. In addition, development of collaborative relationship with suppliers and partners can enhance the effect of SCF and SCP, making Sri Lanka apparel manufacturers more competent to perform international standard. Future studies are encouraged to take these findings to other sectors and regions to explore the influence of new technologies and other external factors. In this way, it would be possible to achieve more advancements in the SCM practices in response to the current global market challenges.
