This vision paper proposes that business and IT professionals must re-focus on building business cases to address strategic gaps in overall IT service delivery improvement. We need a financial model that addresses true service lifecycle costs and benefits, to break through the traditional IT silos of Strategy, Development and Operations. While much progress has been made addressing discrete IT process improvements and subsequent return on investment (ROI), little has been done to address IT service collaboration and investment across the broader IT organization including Strategy, Development and Operations. ITIL V3 now provides a broader framework to begin addressing full IT service lifecycle and infrastructure improvements, yet it needs a next generation ROI model to help quantify and communicate the specific benefits of this lifecycle approach.
