7.7. SUMMARY
Once you get past the hype surrounding SOA and take a close look at it, there is significant, practical value for organizations to capitalize on. Moreover, this value is tangible, and a definable ROI for SOA can actually be determined. The calculation of SOA ROI is still fairly immature. In time, we will no doubt have more comprehensive models for calculating and measuring the value of an SOA initiative. For now, we have some solid guidelines for short-term (tactical) and long-term (strategic) SOA ROI and two ROI calculation models that have emerged in the middle (operational).
SOA adoption does not need to be approached blindly. Clients, investors, and sponsors expect tangible data on which to base investment decisions. SOA should be no exception. An ROI for SOA initiatives can be provided and a roadmap for SOA adoption can be undertaken using incremental, measured steps.
SOA can align and transform your organization and you do not have to harvest your internal organs or lease your office as a bingo parlor on the weekend in order to pay for it.
