Ability to omit damage is not only a must but a crucial aspect of every negotiation. 
The easiest, dating back thousands of years, mantra for negotiation, to mitigate any damages to the business, economy, people and supply chain is working toward mutual success from each party. The most famous example to understand the need for each party is the orange research. 
Two participants are given a task to negotiate for an orange needed to maintain their business afloat, and each is told that under no circumstances they to falter. Without the right mindset, this exercise is not solvable, as each of the participants cannot give up the orange or they fail and so will their business. Unless they have a mutual success mindset. 
Each participant is told that the part of the orange is needed to make their product unique for their business but they both do not know of each other's need; therefore unless they move away from trying to get the best deal for themselves, they cannot complete this exercise successfully. When even one of the participants looks at the challenge with an open mind and the ability to understand the counterpart's need to satisfy their own, then, and only then both subjects will benefit. One of the participants is told that they need the skin of the orange as this is the secret ingredient in their best selling cake and this is the last orange in the world. The other participant is told that they need the inside of the orange to make a juice, so the company can replicate the tase as this is the only orange in the world. Both parties need the orange but they need other parts of the orange and if the mutual needs are understood then, they will very quickly conclude and the negotiation is a success without the need to give up the part of the orange needed for their business. 
Whatever is the subject of negotiation, the ability to understand and identify what the counterpart would need to make the deal is a success, is a solution that will bring each party to conclude quickly and with success and great mutual respect. To truly understand what the other party needs from the deal, there is a process of relationship building and rapport to be able to ask the right questions about the success of the deal. Each person want to make the best deal so they can shine out in front of their bosses, nevertheless, they also have a target and sometimes the target is not monetary. Each business needs to make money, each employee needs to bring in their worth otherwise there will be no business. This is the first, leading principle, and the underlying need is the true success that a deal has to deliver. 
Understanding the need and level of success from the counterpart will enable risk mitigation and successful outcome for all parties. 
A great negotiator always aims for long terms solution and relationship to deliver the best value from the negotiation process and therefore is mindful of that long terms goal throughout the negotiation process. Many risks are averted when the negotiation outcome has the longterm solution as an outcome.
