Abstract

At the last phase of an IT project, it will transfer to the operations team. It is critical to ensure the change management process integrated between project and operations is working smoothly. The study highlights lessons from implementing project management integrated with ITIL. This research is conducted on a multinational Fast-Moving Consumer Goods (FMCG) company that has already implemented project management integrated with ITIL. The study adopts PMBOK and ITIL frameworks, previous studies, and guided interviews, which are then analyzed using socio-technical aspects. This research can enrich existing literature, especially regarding IT project management and service areas. The study concludes that implementing project management integrated with ITIL brings a steadier process to IT projects. One of the socio-technical aspects changed, and the others should be adjusted. Each implementation phase results in different Socio-Technical Systems (STS) components. Nevertheless, as a whole implementation project, the company has already completed all components required.

Abstract

Effort estimation is crucial in software development, especially in Agile projects. The 2020 Standish Group survey found that only 31% of software projects success. The success of a software development project depends on the accuracy of effort estimation. This research aims to analyze studies related to effort estimation methods in Agile software development to identify related issues. A systematic literature review by Kitchenham was conducted across Emerald, Science Direct, Scopus, SpringerLink, and IEEE databases and identified 239 relevant studies from 2018 and 2023, ultimately focusing on 40 studies about effort estimation challenges in Agile software development. The research revealed 59 issues related to various estimation methods. The main challenge in effort estimation for Agile software development is team experience and limited knowledge about the domain, which results in inaccurate estimation result. Requirements’ details, tasks complexity, and lack of data will complicate problem-solving and the prediction of the duration of completion. Reliance on expert judgment will increase the risk of bias and inaccuracy in estimates. These challenges increase the likelihood of project failure due to a mismatch between initial planning and reality as development progresses.

Abstract

New methods and best practices are being used to enhance the software lifecycle because of the recent expansion of the software industry. Agile development approaches have also been widely used, and they have positively affected people's lives and the operations of enterprises. Although agility makes working with developers easier, it does not offer enough chances to collaborate with users. In early Agile formulations, User Experience (UX) was not recognized as a distinct part of software development. The tricky part is figuring out where to integrate them and how to merge them so that the two parts interact. Combining user experience with Agile approaches is the subject of this research's proposed systematic literature review (SLR). This research found ten relevant studies highlighting the growing interest and research in merging these two critical areas of software engineering. In conclusion, this research found some papers or studies integrating user experience into Agile methodologies. Many techniques are used, and all studies have different approaches to integrate them.

Abstract

GS is an Indonesian government higher education institution (GHEI) that uses work productivity (WP) and work discipline (WD) applications to calculate monthly performance. However, GS's monthly performance throughout 2023 was below target. The implementation of business intelligence (BI) was considered the best integration solution for data analysis and visualization for GS management. Given the high cost and risk of implementation, this study focuses on IT project management success factors that include organizational culture, knowledge sharing, and open innovation. Data from 94 respondents were processed using PLS-SEM, resulting in two model scenarios: inbound open innovation positively impacts outbound open innovation in one scenario, and vice versa in the other. This research recommends GS to prioritize organizational culture and knowledge sharing in IT project strategy through open innovation. The research model can be used as a reference for further research due to its 87.5% success rate.

Abstract

Non-communicable diseases (NCDs) account for 53% of premature deaths globally, posing significant challenges to healthcare systems. In Indonesia, the rising prevalence of obesity and overweight among adults highlights the urgent need for innovative interventions to promote healthier lifestyles. Mobile diet applications have emerged as a promising solution, offering accessible tools for health monitoring and behaviour change. However, adoption rates in Indonesia remain low due to a limited understanding of the factors influencing user acceptance. This study aims to analyze the determinants of mobile diet application adoption among Indonesian adults using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) framework, extended with five external factors: trust, perceived health threat, health consciousness, health conditions, and body image. Data were collected through an online survey with 218 respondents who had used diet applications such as Cronometer, FastEasy, and MyFitnessPal within the past six months. Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed for analysis. The findings reveal that effort expectancy, social influence, price value, health conditions, and body image significantly influence adoption. In contrast, performance expectancy, hedonic motivation, trust, perceived health threat, and health consciousness were not significant predictors. These results underscore the importance of intuitive interface design, community-driven features, and personalization based on health data to enhance user engagement and adoption. This study contributes to understanding user behaviour in health technology adoption in a developing country. It offers practical recommendations for application developers and policymakers to optimize the use of mobile diet applications as part of broader efforts to address NCD challenges in Indonesia.

Abstract

As cross-organizational collaboration increases, balancing data utility with privacy protection becomes essential. This study addresses the challenge by implementing Privacy-Preserving Record Linkage (PPRL) using a deterministic hashing approach at an Indonesian manufacturing firm and a leasing company. The system employs a dual-layer hashing technique (MD5 followed by salted SHA-256) to securely link standardized identifiers without revealing raw personal data. The objective was to enhance Customer Relationship Management (CRM) by identifying shared customers for targeted outreach. The approach yielded 2.6 million matched records out of over 36 million, enabling the leasing firm to achieve a 2-4% conversion rate through personalized campaigns. Results demonstrate high efficiency, scalability, and compliance with Indonesia’s data protection law, offering a replicable framework for privacy-conscious data integration in regulated environments.

Abstract

Risk management in the software development lifecycle (SDLC) is a continuous process that addresses risks throughout a system's lifecycle, including acquisition, development, maintenance, or operation. Despite its importance, ineffective risk management practices can lead to project failures, impacting organizations financially and reputationally. Therefore, there is a need for a systematic understanding of risk management practices in SDLC. This study conducts a Systematic Literature Review (SLR) related to risk management activities performed by previous research during the SDLC. The SLR method combines Kitchenham with the toll-gate method to select literature for use. This SLR aims to investigate activities in traditional waterfall and agile development processes, which will be mapped into risk management activities in SDLC according to ISO 16085:202. Additionally, the review highlights the challenges encountered in implementing risk management in the SDLC process, including project complexity, adherence to policies and standards, lack of communication, lack of resources, and organizational culture.
