Ewert's Law is a principle in the field of computer science that suggests the complexity of a software system increases exponentially as the number of features or components grows. This means that as developers add more functionalities, the effort required to maintain and manage the system also rises significantly. The law highlights the challenges of software development, emphasizing the importance of careful planning and design. By understanding Ewert's Law, developers can better anticipate potential issues and work towards creating more manageable and efficient systems, ultimately leading to improved software quality and user experience.
