All forms of partnership have a common factor where both partners are convinced that they will achieve gains or benefits from the partnership. So, in the successful partnership, both parties benefit from the partnership and the desired benefits are clear from the beginning. In other words, they share the risks and benefits. The logic of the partnership is based on the fact that each party has certain characteristics and strengths. By their cooperation, they use such strengths to build two teams which are complementary to each other.
