To work BATNA out. you need to do three activities before starting negotiation:
Firstly, all possibilities which may occur ifour negotiations fail musi be pointed out.
Secondly. few best possibilities sliould be chosen and improved. It means planningand modifying these possibilities into practical activities.
And finally, the one that seems to be the most attractive should be chosen.
The better BATNA. the better chances of influencing the condition of negotiated agreement are (morę strength, self-confidence).
If both parties have attractive BATNA, the best result of negotiations for both parties can be actually not reaching an agreement.
