The main disadvatages of using EAI systems:
•Constant change: The very nature of EAI is dynamic and requires dynamic project managers to manage their implementation.
•Lack of EAI experts : EAI requires knowledge of MANY issues and technical aspects.
•EAI is a tool paradigm: EAI is not a tool, but rather a SYSTEM and should be implemented as such.
•Building interfaces is an art : Engineering the solution is not sufficient. Solutions need to be negotiated with USER departments to reach a common consensus on the final outcome. A lack of consensus on interface DESIGNS leads to excessive effort to map between various systems data requirements.
•Loss of detail : Information that seemed unimportant at an earlier STAGE may become crucial later.
•Accountability : Since so many departments have many conflicting requirements, there should be clear accountability for the system's final structure.
