Small satellite systems are increasingly transforming industries such as communication, earth observation, and scientific research. As these systems evolve, traditional Document-Based Systems Engineering (DBSE) methods, which have long been employed in larger, more conventional space projects, often need to meet the fast-paced demands of small satellite development. Traditional DBSE frequently leads to inefficiencies, costly errors, and delays that escalate project timelines and budgets. The need for a more agile and adaptive approach to system design, integration, and validation has never been greater. Model-Based Systems Engineering (MBSE) offers a promising solution, providing a more integrated and flexible framework that can handle small satellite initiatives' complexity and rapid evolution. This paper explores the limitations of traditional systems engineering in this context and underscores the growing necessity of adopting MBSE. Through a comprehensive literature review, this study identifies critical advantages of MBSE, including improved stakeholder communication, enhanced traceability of requirements and design decisions, and earlier identification of potential system risks. These benefits translate into faster, more cost-effective engineering processes, ultimately leading to higher-quality small satellite systems. The findings suggest that MBSE not only addresses the challenges faced by traditional methods but also positions small satellite development for future success in a highly competitive field. This research highlights MBSE's transformative potential, offering valuable insights for industry practitioners and researchers seeking to improve engineering practices and promote innovation in small satellite systems.
