brand strategy
Brand strategy is what and how your organization provides and communicates a needed product or service to a target market.
As people's needs change, your organization may evolve and provide new products and/or new ways of communicating with your audiences.
Your strategy may change but your brand (aka ego aka core) can, and probably should, remain the same - unless you are failing miserably.
branding
