Based on seminal research into the link between emotional intelligence and negotiation/influencing skills in business, this short publication provides all those involved in commercial negotiations with a simple ‘handbook’ of practical advice to develop their emotional intelligence and deliver better negotiated outcomes. It is relevant for all those involved in negotiations, irrespective of which side of the table they are sitting. The work is based on initial research sampling by the author and Professor Malcolm Higgs at the the Henley Business School in the purchasing profession during 2002 and demonstrates the link between E.I. and improved commercial negotiation.
