For leaders of major groups and mid-sized companies, any opportunity of meeting one another is priceless. While developing business streams is a significant challenge, it is not the only one. Indeed, during formal meetings it is difficult, not to say impossible to explore such enriching aspects as another company's corporate culture, which sometimes can be similar to your own, or to get to know one another, to share common values, to gain mutual respect for topics that have nothing to do with business. And while contracts are the result of the rational encounter of a need and a solution, implementing and extending them will depend in a big way on the efforts made by the men and women who are working together towards their success. In addition, quite a number of conflicts and difficulties can be smoothed over whenever the leaders have successfully created a relationship.
