more complexity of the ERP implementation
higher cost.

– based on ‘home’ country assumptions Practices and assumptions may not transfer
across borders

Reasons to Adopt ERP One face to the customer Knowing “what is possible” in terms of
organizational inventory Eliminating redundancy Consolidation

Reasons Not to Adopt
Cost Loss of competitive advantage Resistance to change Poor cultural fit

Alternatives? Open Source ERP (+ Support Vendors)
e.g. GNU Enterprise, Apache OFBiz ERP for SMEs
less expensive systems with fewer "bells and whistles"
ERP ASPs (Application Service Providers) ASPs will host and maintain the software for you

26
Post-ERP? Service-Oriented Architectures (SOA) hold
some promise as the natural evolution from ERP
The foundation of SOA is standardization based upon web services interoperability standards.
SOA does not replace ERP provides the ability to “loosely couple” services
(business functions).
