But IT managers attempting integration face daunting challenges–disparate legacy systems; a hodgepodge of hardware, operating systems, and networking technology; proprietary packaged applications; and more. For example, point-to-point middleware, while providing value within the enterprise, does not–and cannot–provide the ultimate solution.
Traditional Systems Traditional systems also known as “legacy systems” are stovepipe applications that may exist with many other stovepipe applications in a centralized environment. Inventory control applications that exist within the sales organization and the resume-tracking system in human resources are also examples of stovepipe applications. These include call center applications, sales automation applications, and inventory control applications.

Unfortunately, many of these business-critical systems are difficult to adapt to allow them to communicate and share information with other, more advanced systems. The only limitations that developers face are the specific features and functions of the application interfaces.

This allows any and all information required for all transactions to be immediately available no matter where the information is located in the enterprise. While there are methodologies and procedures that can be applied, most competent managers understand the degree of value when applying EAI without over-analyzing this information.
