Having a BATNA:
Increases assertiveness (A): Knowing the fallback position empowers the buyer to negotiate more confidently.
Reduces the chance of a poor agreement (B): A BATNA ensures the buyer does not feel pressured to accept suboptimal terms.
Identifies walk-away points (F): It sets a clear boundary, allowing the buyer to exit negotiations if terms don't meet minimum requirements.

Professional buyers, when planning or engaging in negotiation with suppliers, should always be aware ofwhere the intended and actual relationship with this supplier is positioned on the 'spectrum' or 'continuum' of commercial relationships. The relationship spectrum describes the range of commercial relationships between a buyer and supplier based on richness of communication, longevity and mutual dependence.
