Final answer:
A comprehensive classification scheme is more important than being mutually exclusive for system components.
Step-by-step explanation:
The classification scheme for system components is more important to be comprehensive rather than mutually exclusive. A comprehensive classification includes all possible components, ensuring that nothing is left out. On the other hand, being mutually exclusive means that each component only belongs to a single category and does not overlap with other categories. While both aspects are important, a comprehensive classification is more essential as it provides a complete understanding of the system and allows for more accurate analysis and study.
