(The Library, University of Kelaniya, Sri Lanka, 2023) Peliarachchi, Amalka; Wijayanayake, Janaka
In today's rapidly evolving environment, two critical factors for organizations to maintain their competitive edge are speed to market and adaptability. Over the past ten years, a significant number of organizations have achieved success in delivering IT services by utilizing IT management frameworks. One widely adopted framework in this domain is ITIL, an abbreviation for the IT Infrastructure Library. ITIL serves as a guiding framework, facilitating the attainment of high-quality IT service management at an organizational level. When it comes to software development, it is crucial for managers and development teams to select an appropriate methodology that aligns with their project's needs. Agile software development is one prominent approach based on iterative and incremental development. It has gained significant prominence in the IT industry due to its ability to enhance project development processes. Combining ITIL and Agile methodologies has proven to be a valuable strategy for streamlining project development in the IT industry. This fusion results in what is known as the Agile- ITIL combined framework, often referred to as A-ITIL. This paper primarily focuses on the integration of ITIL processes with agile phases, shedding light on the amalgamation of ITIL and Agile with other frameworks and technologies. Furthermore, it examines the utilization of ITIL and Agile in various companies, offering valuable insights into how these methodologies can be applied effectively. Consequently, this publication is a valuable resource for researchers seeking comprehensive knowledge in the ITIL and Agile-related domains. It aims to identify potential avenues for future research and development in this dynamic field.
Analysing the impact of student engagement on learning outcomes in e-learning platforms: a systematic review of literature
(The Library, University of Kelaniya, Sri Lanka, 2023) Wijayanayake, Janaka; Erandika, Lakshani; Prasadika, Jinendri
This paper explores the impact of student engagement on learning outcomes in E-learning platforms. It seeks to provide practical insights for educators and institutions as they navigate the digital education landscape. This systematic literature review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, utilising its methodology to identify and select the most relevant literature, resulting in the inclusion of 54 papers for review. Also, this analysis identified a notable gap in research related to the relationship between student engagement and learning outcomes in Sri Lanka. Prior studies, mostly conducted in European countries, might not be directly applicable to the Sri Lankan context due to differing infrastructure and unique student behaviours and learning expectations. The distinctiveness in Sri Lanka's infrastructure and students' learning attitudes makes the direct application of these findings from European studies challenging. Additionally, none of the existing studies in this area have utilised the Community of Inquiry (CoI) framework, which is a valuable tool for assessing student engagement in E-learning platforms. Also, as found in the literature, Information Technology (IT) students tend to possess higher technical expertise compared to students from other disciplines. Therefore, when conducting research in the context of Information Technology students, it is not a critical influencing factor to consider. This systematic review aims to bring together the existing literature and identify research gaps for context-specific investigations. By addressing these gaps and incorporating a Sri Lankan perspective, future researchers can further explore this context to make decisions in the field of digital education and contribute to the improvement of E-learning experiences in Sri Lanka.
Analyzing the Impact of Student Engagement on Learning Outcomes in E-learning Platforms: Case on Programming Language Courses
(Institute of Electrical and Electronics Engineers (IEEE), 2024) Lakshani, Erandika; Wijayanayake, Janaka; Prasadika, Jinendri
This study explores how students engage with e-learning platforms and how it relates to their academic success, focusing on programming language learning among Information Technology (IT) undergraduates in Sri Lanka. This study employs the Community of Inquiry (CoI) framework in conjunction with the evaluation of academic pressure to measure student engagement. The research aims to understand the impact of cognitive presence, social presence, and teaching presence on learning outcomes in e-learning, while also examining how infrastructure plays a moderating role. The data were gathered through a structured questionnaire, and the gathered data were analyzed using SmartPLS 4 software. The findings highlight that cognitive presence, social presence, and teaching presence significantly predict better learning outcomes, emphasizing their crucial role in the effectiveness of e-learning in programming language courses. The study doesn't find a strong connection between the academic pressure felt by undergraduates and the learning outcomes. This suggests that success in e-learning is influenced by various factors beyond traditional academic pressures. Additionally, we investigate the moderating effect of infrastructure on these relationships. Unexpectedly, the study reveals that infrastructure doesn't significantly change the connections between cognitive presence, social presence, and teaching presence on learning outcomes. In simpler terms, the technical support provided doesn't seem to alter how these elements impact student success in this context. This study offers valuable insights into the intricate dynamics of student engagement, academic pressure, and infrastructure within the realm of e-learning. These findings hold significance for educators, policymakers, and researchers in the field of education, providing actionable knowledge to enhance support for students navigating e-learning environments.
Aspect Based Multi-Class Sentiment Dataset for Bilingual eWOM of Commercial Food Products
(Faculty of Computing and Technology (FCT), University of Kelaniya, Sri Lanka, 2021) Edirisuriya, Binguni; Asanka, Dinesh; Wijayanayake, Janaka
Aspect-Based Sentiment Analysis for product review opinion analysis is commonly utilized by the commercial food products manufacturing businesses to drive decisions regarding products. However, the general consumers are not facilitated with decision making ready end-user applications which generates insights to arrive at the purchase decision at the time of purchase due to the unavailability of products’ attribute-wise analysis-ready data. Although Electronic Word of Mouth (eWOM) platforms are comprised of opinions with a diversity of languages and expression formats, themselves do not generate any value to make comparable decision making. Hence, there is an existing gap of impactful information retrieval by the consumer to aid the purchase. Therefore, creating a publicly available analysis-ready dataset for the commercial food product domain contributes significantly to the Sri Lankan consumers and Government organizations. Through our research work, a manually annotated bilingual eWOM opinion text dataset for selected commercial food products categories has been delivered in which the opinions expressed in the Sinhala language have been translated into English language and each opinion has been manually rated into five levels by two domain experts. Two product attributes, “Price of the product”, “Safeness of product” have been considered as aspects to conduct the Aspect-Based Sentiment Analysis. This study describes the sub-tasks performed to conduct the Aspect- Based Sentiment Analysis on the dataset along with the basic statistical evaluation of the dataset. We have presented results on the performance of the dataset by utilizing an existing Long Short-Term Memory Model.
Evaluating Business as Usual Activities between Agile and Information Technology Infrastructure Library (A-ITIL): Industry Practitioners’ Point of View
(Department of Industrial Management, Faculty of Science, University of Kelaniya Sri Lanka, 2023) Peliarachchi, Amalka; Wijayanayake, Janaka
Although the Information Technology Infrastructure Library (ITIL) aims to manage the entire lifecycle of an IT service, the protocols of ITIL do not directly control the initiatives that lead to the formation or changes of IT services. However, researchers have explored combining the Waterfall lifecycle, a conventional software development methodology, with the extensive ITIL literature. Unfortunately, they have faced challenges in integrating the agile methodology with ITIL to accurately manage the project lifecycle. In order to address this issue and facilitate Business As Usual (BAU) activities in the IT sector; a proposed framework called A-ITIL (Agile-ITIL combined framework) has been introduced. This research primarily focuses on the requirement for combining the Agile approach with ITIL in BAU tasks within the IT industry. By utilizing shared questionnaires and related research articles, the critical success factors for integrating Agile with ITIL in BAU activities have been identified. The research process began by gathering sample data through an online questionnaire to assess the Agile-ITIL literacy of the respondents and the necessity of combining Agile and ITIL in BAU. A second questionnaire was then used to rate the transparency of transitioning BAU between Agile and ITIL, document the challenges faced during this transition, and propose mitigating strategies for these primary challenges, involving key stakeholders. Subsequently, a user story was created based on the results of the shared questionnaires to identify key points for the A-ITIL framework. Furthermore, the research articles were analyzed to identify key success factors for Agile and ITIL separately. Finally, an A-ITIL conceptual model was designed by mapping the existing research findings, incorporating key success factors from both Agile and ITIL, the key points identified in the user story, and insights from an interview with Agile/ITIL experts. These findings form the foundation for integrating Agile-ITIL and ensuring smooth BAU activities within IT organizations.

(Department of Industrial Management, Faculty of Science, University of Kelaniya Sri Lanka, 2023) Prabagaran, Sathurvanan; Wijayanayake, Janaka; Jayasinghe, Shan
Work-life balance is a motivational factor which causes employees to work in the organization steadily in each situation. This study is aimed to examine the organizational characteristics that impact the work-life balance of teleworkers in the IT industry of Sri Lanka in the post- pandemic era. A thorough systematic literature review using the PRISMA framework was conducted to identify which characteristics which were influence the work-life balance of teleworkers. Identified most appropriate characteristics were shortlisted by the industry expert. The conceptual framework was developed by using this past literature support, and then the actual characteristics were identified through the data analysis process. For this purpose, the questionnaire targeted employees who were working in the IT sector in Sri Lanka. Samples (n=149) were collected through online questionnaires and then collected samples were subjected to preliminary data analysis using the IBM SPSS tool to clean the data. Then the PLS-SEM method was used to find the relationship between the variables. The study found that strategies are the most significant factor to determine a better work-life balance, though management support, technical support, and organizational culture have relationships between them but that are not significant factors to drive better work-life balance in the post-pandemic era. And the study concluded that if organizations need to more focus on strategies, especially job control, and decision-making strategies then they can maintain a better work-life balance for the IT sector employees in Sri Lanka after the pandemic period.
