Abstract

This article presents a user experience analysis of LinkedIn using the Usability Metric for User Experience (UMUX). The study aims to assess the usability and user satisfaction of LinkedIn, identify areas for improve-ment, and propose hypotheses for future research. The problem addressed in this research is the need to evalu-ate the user experience of LinkedIn, a popular professional networking platform. The solution offered is to uti-lize the UMUX metric as a comprehensive tool for assessing usability and user satisfaction. The objectives of the study are to measure the effectiveness, efficiency, satisfaction, and overall usability of LinkedIn, as well as to identify specific areas for improvement. Data were collected through online questionnaires from LinkedIn users. The UMUX scores were calculated, indicating a moderate level of user satisfaction and perceived usa-bility of LinkedIn. These findings suggest that LinkedIn is perceived as a useful platform for professional goals, but there is room for improvement in terms of efficiency and overall user satisfaction. Hypotheses for future research include enhancing efficiency to improve satisfaction, improving overall satisfaction for in-creased engagement and retention, and optimizing the mobile experience. The study provides valuable insights for LinkedIn to enhance user satisfaction, engagement, and usability. Further research can explore additional usability metrics and investigate the impact of implemented improvements.

Abstract

The creative economy assessment program involves high domain complexity and multi-stakeholder workflows that conventional content management systems fail to accommodate adequately. This paper presents the development of a Domain-Driven Design (DDD)-based Content Management System (CMS) for the creative economy assessment program, integrated with Agile (Scrum) development methodology. The study employed strategic DDD design including bounded context identification, ubiquitous language definition, and context mapping, followed by tactical design comprising entity, value object, aggregate, domain service, domain event, and repository pattern specifications. A Headless CMS architecture using Laravel 10 as the backend API and Next.js 15 as the frontend was implemented across four sprint cycles, resulting in a modular, maintainable system with clear domain separation. The system successfully modeled four bounded contexts (Borang Management, Assessment, User Management, Notification) and implemented Clean Architecture layering validated through Deptrac. Results demonstrate that the DDD approach effectively addresses creative economy assessment domain complexity, enabling independent development and testing of each bounded context while maintaining business rule integrity through aggregate design and domain events.
