Training is necessary

Universities in the UK and the U.S. that teach courses like Project Management has already realized the importance of negotiation and has added this as a module. But this ecosystem is yet to be developed in India. The educational institutions have to realize the importance of proper negotiation management and have to start training students in this. Entrepreneurs would much benefit from crash courses on the same. If these are not possible then reading books on negotiation written by some of the best negotiators and observing how the task is done by them, if possible, can help. Videos of good negotiations can be found online, going through them might also help. Remember practice makes it perfect. Once you have acquired enough skills and knowledge, practice. Consult with people who you know are good at it and ask pointers from them as well.
