solved If you remember, you have done 3-tasks last week that

If you remember, you have done 3-tasks last week that are; tasks 9, 11, and 30, see the attached file named “Final project tasks”.
Additional to these 3-tasks that you have done last week. Now I have one more task and I want you to do it. This task is:
Task 17 – Negotiation in Projects: To develop general rules for the negotiation process.
So, from the attached file that titled (Negotiation) you can find 2-articles talking about Negotiation in Projects. I believe these 2 articles may give you a clear picture about what to write and how to write this task. 
When you write the paper, I want you to focus on the 1st article; part “Options for negotiation style are (Fisher & Ury, 1992) as it is Very Important in this task.
“Options for negotiation style are (Fisher & Ury, 1992)

Hard (controlling) :Hard bargaining is adversarial—you assume that your opponent is your enemy and the only way you can win is if he or she loses. So you bargain in a very aggressive, competitive way.
Soft (giving in) : Soft bargaining is just the opposite. Your relationship with your opponent is so important that you concede much more easily than you should. You get taken advantage of in your effort to please, and while agreement is reached easily, it is seldom a wise one.
Principled (much more effective): P2O2
People: Separate the people from the problem
Positions: Focus on interests not positions
Options: Generate options for mutual gain before choosing
Objective Criteria: Decide based on objective criteria
BATNA (Best Alternative to Negotiated Agreement): Know theirs. Know & improve yours.
Good negotiations consist of a relentless search for the Third Alternative:
We humans are presently conditioned to expect our relationships to be win/lose. 
–  View most situations from an “either/or” point of view: either I win or I lose

–  It has to be one or the other.
There is a third alternative. 
–  May be harder to find, but there almost always exists a third way of doing things where no one loses

–  Or at worst are assured that the loss has been minimized and fairly shared
Minimizes and distributes the loss so it has the least negative effect

This is the win-win way—this is synergy.
Sources of power in negotiation are:
Developing good working relationships among people negotiating
Understanding interests
Inventing an elegant option

Using external standards and benchmarks
Developing a good BATNA

Understanding their BATNA

Making a carefully crafted commitment: an offer, something you will do, something you will not do.

The stages in a Negotiation Lifecycle are depicted in this chart (Exhibit 1). It is not always a given that negotiations should happen, especially if the status quo is fine or other alternatives exist. But if needs exist for opposing parties to reach a mutual solution, engage dutifully in each step in the lifecycle.
So please read the articles (especially the 1st article) as it has valuable info about the task.
