This document lists various ways that brands can be killed or damaged, such as by over-branding, losing focus, diluting the brand, becoming undifferentiated from competitors, forgetting customer values, abandoning core values, providing poor customer service, failing to adapt to new technologies or market trends, and making decisions based on ego or complacency rather than market realities. Overall, the key messages are that brands must stay focused on their core identity and customer value proposition, listen to customers, and adapt to remain relevant in a changing marketplace.
