What are the mistakes that must be avoided in any negotiation?

Not being able to a good listener,not seperating problem from the people,not having multiple options,having an win-lose mindset.

1) Never think that you know what they want.2) Never think of $ price as #1 priority.3) Never give promises or guarantees, unless such promises or guarantees have a good financial background.4) Never forget to do your homework and research before negotiations.5) Never speak bad about competitors.

Here I can mention three mistakes that can be avoided during any negotiation 1.Don't make assumption. Key successful negotiation is being prepared that means a lot more than just knowing numbers and facts. 2.Don't rush through it.Negotiation takes time especially if you want them to go smoothly. not only that but as you know in negotiation.must must win to win to situation,no one want to gain than others. 3. Don't take any thing personally .Means of negotiation is understand each other means that in every group of people when people talk to agreed something,some people can take some of the words personally so that is bigger mistake you have to avoid

Lack of confidence, Not asking, talking too much and not building relationship first

Non-commital commitments, self boasting, improper delegation of work prerequisites, revealing the exigency, competitors and thier offers.

Don't be so tight or firm. It's good to have open door policies where you can end up to meet the requirement on both ends and complete the transition smoothly.
