Some CIOs, according to Beth Enslow, senior VP of enterprise research at Aberdeen Group, seem to be waiting for their enterprise vendors to solve their supply chain technology problems for them.They could have a long wait ahead of them.On-demand supply chain applications just aren\u2019t their ERP vendors\u2019 core competency. \u201cPeopleSoft, even with 300 different software modules, did not have an EDI translations software suite,\u201d says George Muller, VP and CIO of Imperial Sugar, who uses Sterling Commerce\u2019s services for order management and inventory. \u201cPeopleSoft would handle everything very well within [our] four walls, but outside the four walls, PeopleSoft was behind the curve.\u201dA possible reason for ERP vendors\u2019 reluctance to develop tools to integrate their customers\u2019 systems with their suppliers\u2019 and customers\u2019 systems is that it would impact their business model: selling on-premises software to a captive customer base. With the new, hosted model, customers of the enterprise software vendors could conceivably \u201cturn off\u201d the connection and go to someone else if they chose.Representatives from SAP and Oracle, the biggest enterprise systems vendors, say that they are following the on-demand, hosted SCM market with interest, but, so far, don\u2019t have anything to offer. \u201cWe are looking at the demand for this market, but we are not yet offering an on-demand model with these kinds of solutions,\u201d says Hans Thalbauer, VP of supply chain management solution management at SAP.\u201cWhen you look at that opportunity space, that is not a service that Oracle has much interest in and competency in,\u201d says Julian Trotman, director of enterprise integration applications development at Oracle.However, both point to their companies\u2019 fledgling on-demand CRM offerings to illustrate their technical capabilities within the on-demand model. \u201cIt\u2019s a model that we\u2019ve tried to hone over the last three to four years,\u201d says Trotman. \u201cIt\u2019s going to be a large part of our business going forward.\u201dAs for the rise of the on-demand SCM vendors, SAP\u2019s Thalbauer doesn\u2019t seem too worried about E2open, GXS and the others. \u201cI don\u2019t view them as a threat,\u201d he says.
