Enterprise resource planning (ERP) systems are undergoing big changes, in terms of functionality and suitability for multiple industries. Lee Geishecker, vice president and general manager with AMR Research, talks about how the term has broadened to include many different business applications and industries. Traditional ERP vendors are offering a wide range of supply-chain applications that integrate with the backbone technology. Meanwhile, so-called best-of-breed vendors continue to offer systems that address discrete areas of the supply chain, such as transportation and warehousing. Geishecker discusses two other related trends - service-oriented architecture (SOA), offering a means of integrating disparate systems on one platform, and software as a service (SaaS), whereby numerous applications are provided in a hosted, "on-demand" version.
