Pragmatic recommendations for leveraging Enterprise Business Architecture (EBA) to avoid common pitfalls of ERP/CRM projects. While there is ample literature on the theory and concepts of Enterprise Business Architecture, this talk distills recommendations gleaned from actually having tried to apply EBA on Sun Microsystems "IBIS" project. This multi-year, multi-deployment program impacted more than 250 business processes spanning virtually all of Sun\'s core value streams: Concept-to-Offering, Campaign-to-Sales Order, Order-to-Cash, Supply Chain Plan-to-Stock, Issue-to-Resolution, and Financial Accounting-to-Reporting. It targeted more than 50% of Sun\'s entire application portfolio for replacement. The presentation describes how EBA can be leveraged to avoid the cost overruns, schedule slips, and missed business expectations that are often encountered on ERP/CRM implementation efforts.
