A negotiator uses disorder to confuse the other side. This tactic deliberately mixes things up. It can be used to forestall a deadlock; make the other side work harder; force through a last-minute demand; or allow one to retreat from a prior concession. Sometimes it is used just to see how well the other person keeps their wits under pressure. Disorder complicates the negotiation and the person using the disorder tactic hopes to profit from this confusion. Examples: the introduction of new product-price schedules; new quality standards or revised specifications; some services that were bundled are now unbundled; new delivery dates; suddenly apples can't be compared to apples and cost comparisons become almost impossible to make.
