Developing and Deploying Siebel Business Applications > Introducing the Business Case >
NREC's Business Requirements
By progressing through the Discovery and Design stages of Siebel's eRoadmap methodology, the project team identified and documented the detailed requirements. These requirements provide the basis for the tasks covered in later chapters.
Some of these requirements are satisfied using standard Siebel functionality. Other requirements cannot be satisfied with standard functionality and are identified as gaps. Gaps require configuration work to modify the standard application to meet the specific requirements.
NOTE: As a general rule, a gap analysis results in less than 25% of the functionality requiring customization. If the gap is more than 25%, it may mean that standard functionality is not being employed. It is always a good practice to engage Oracle's Siebel Expert Services for a Configuration Design Review to verify gaps and required configuration changes.
