Data networks have traditionally been single application or system oriented. These networks evolved to support many applications used by various business units. Large organizations often maintain multiple data networks supporting various technologies, thereby limiting interoperability and costing too much. The lack of industry standards for networking and application interoperability in the past has contributed to a less than optimal way of providing connectivity. Today, competitive forces drive businesses to utilize all resources, including Information Technology more effectively.
Enterprise networks facilitate how work groups exchange information and collaborate.
To be effective, these networks must be well planned, and implemented. Three key success factors common to effective business. First is integrating the network into the organization's business strategy, ensuring the flexibility that today's businesses require. New business opportunities require new applications that need network support. An integrated planning process ensures that the network can meet new demands and support new directions.
