IT portfolio planning is often a technology-driven exercise, looking at IT cost metrics as a decision-making tool. This approach creates tremendous business risk while ignoring business-driven perspectives and related strategies. Business architecture provides the business perspective required to ensure that IT portfolio planning is no longer just technology-driven, but considers a complete business perspective and achieves business goals as a top priority. Topics include the role of business architecture in the evolution of enterprise architecture, tracing business strategy through solution deployments, essential business/IT architecture mapping concepts and shifting to a business-driven IT investment model.
