EIM Architecture Planning Requirements

You must consider the size and complexity of the implementation before executing any single item with the Siebel application. Aspects that have a direct impact on how the production application will perform may not be your highest priority when you initially begin your Siebel implementation. However, the decisions made during the initial phases of an implementation have a far reaching impact, not only on performance and scalability but also on the overall maintenance of the Siebel application.

It is strongly recommended to have a Siebel certified principal consultant or architecture specialist from Expert Services involved in designing the most effective logical and physical architecture for your organization. This includes capacity planning and system sizing, physical database layout, and other key architecture items.
