1 Overview
1.1 Purpose
This document is intended to be used as a guide for the design and deployment of EIM
interfaces to support the delivery of Siebel based projects at BT. It will be of particular relevance
to the delivery of OneSiebel (aka Account Managed Platform, AMP) and OneView (aka Volume
Siebel Release 6).
This document is split into two main sections as follows:
1. Siebel EIM Best Practice
• This section details techniques to be adopted to ensure that EIM interfaces and their
configurations adhere to Siebel and BT Best Practices.
2. OneView Release 4 data load Lessons Learned
• This section details the key lessons learned from the OneView (aka Volume Siebel, Big
Data, CCC) bulk data load of Billing Accounts, Assets and Consumer Updates into the
OneView Siebel instance.
This document has been assembled from experience from BT’s eVolve and Volume platforms.
These applications are fed data via ODM controlled data loads. Where processes other than
ODM will drive EIM interfaces (e.g. Converge to OneSiebel migration jobs) then some ODM
related content will still be relevant and so all sections should be read.
1.2 What’s not included
• This document is intended to share Best Practice and Lessons Learned and is neither a
High Level nor a Low Level Design. This document should be used to feed into the above
mentioned designs.
• Details of Oracle-Level tuning is not included although some techniques may be
mentioned in the context of other EIM specific parameters or configurations.
• This is not a ‘One Stop Shop’ from which to learn EIM. Instead, this document is
intended to communicate EIM Best Practice.
