Sales negotiation
A supplier hesitates to break with a difficult client. Their BATNA: winning two new accounts. Their WATNA: signing nothing for six months and having to make redundancies. Looking at the WATNA pushes them to negotiate an adjustment rather than storming off out of pride.
Before breaking off, list your concrete and likely worst-case scenario, not merely your hope of a rebound: the WATNA tempers impulsive ruptures.
Prevents emotional walk-outs by making the risk of a commercial vacuum objective.
Weighting the WATNA too heavily makes you timid and leads you to accept mediocre agreements out of fear of the worst.
