Success in today's marketplace is about attracting new customers, but also about retaining existing customers. In many cases existing customers can sell the user's goods and service better than they can. This fact makes it vital to nurture relationships with existing customers and business partners. If fact, they can often tell the users how their products can be improved. Each business, whether it realizes it or not, has a business network. This network consists of any businesses or individuals that participate in the creation or use/consumption of their products. Many businesses realize that this network has a direct impact on their business and that the agents in this network know the shortcomings and additional ways to use its products.
