Today modern companies are directed by buyers. Successful organizations are aware that the key issue is to satisfy buyers’ needs and to maintain good relationship with them. Such companies perceive problems and opportunities fast and act accordingly. In future only such companies that will be able to substitute mass production and generalized market approach with a flexible production and in addition to this constantly look for market gaps for their products and services will be able to survive. Further on such companies will be able to individualize their offer and in this way adjust and come closer to the buyer. However, the old hierarchical structure does not provide for that, therefore, we are nowadays talking about horizontal relationships, even among the suppliers, organizations and their buyers. The only organizational format providing for relationships and cooperation with buyers and suppliers on the one hand and increasing contentedness and successfulness of the employees on the other is a process format. The changes of the environment demand a thorough change of the traditional way of thinking and consequently the operation and organization of a company which wants to be successful or survive in new conditions.
