Closed systems operate in isolation, not taking in external feedback or adjusting to new information. In the material, this rigidity means the system can’t respond to changing needs, conditions, or threats. Without the ability to adapt, performance deteriorates, resources become misaligned, and the system eventually ceases to function—essentially dying. This is why the term is linked to that outcome, whereas open systems that incorporate feedback and adjust tend to survive or thrive.
