Abstract:
Organizations implement Enterprise Resource Planning (ERP)
Systems in order to address the problems pose by disparate applications within
functional areas and to achieve competitive advantages. ERP systems typically
provide elegant technological solutions for organizations information needs
through radical changes in information processing orientation. Due to the
robust nature of these applications and the changes associated with the
implementation, auditors may need to adjust the audit processes and procedures
when auditing in such an environment.
The aim of this study is to present phases of an ERP systems
implementation and its impact on audit process in an organization. The focus is
to identify different phases of the implementation and how auditor can manage
this change. The research is conducted during my training on AS-Solar France
and the samples consist in the implementation of different module in CEGID ERP
System.
