Sales negotiation
A client tries to close each point separately: first the price, then the lead times, then after-sales support. The seller refuses: « Let's discuss everything, nothing is fixed until we have the complete agreement. » In this way he keeps the freedom to adjust the price according to after-sales support and volumes.
Announce from the outset that everything is linked; do not validate any single point before you have the overall picture, so as to preserve your room for trade-offs.
Stops the client locking in your concessions one at a time; opens up swaps between issues.
A single point of disagreement can block the whole, where a partial agreement would at least have reassured.
