                Exempt Organizations Programs)


SUBJECT:     Development and Implementation of an Enterprise Business System (Audit #20041C0230)


The Defense Contract Audit Agency (DCAA) provided auditor involvement concerning the contractor’s development and implementation of an Enterprise Business System (EBS) in accordance with DCAA audit guidance.  The purpose of the assignment was to continue DCAA’s efforts concerning the contractor’s conversion to an EBS by January 1, 2004.  Accordingly, the DCAA provided oversight concerning control requirements as well as comments on concerns identified during the development of the EBS.  Also, subsequent to the contractor’s January 1, 2004, implementation of the EBS, the DCAA performed data conversion accuracy tests and tests of initial accounting data generated by the EBS. 

The DCAA’s involvement to date has not disclosed any system design and configuration issues that would have a significant adverse impact to the Federal Government.  However, the DCAA has noted that the contractor currently maintains an “Issues Log” that describes various problems encountered by users of the EBS and associated corrective actions by functional area.

In August 2004, the DCAA will initiate an accounting system audit to verify corrections of functional area issues and to perform tests designed to render an opinion on the contractor’s overall accounting system and related internal controls.

The information in this report should not be used for purposes other than those intended without prior consultation with the Treasury Inspector General for Tax Administration regarding their applicability.
