True, most firms now try to use metrics such as internal rate of return, return on assets, net present value, or activity-based costing. But besides customer satisfaction there's no consensus or consistency on which measures to use. It's still not a given that ROI should be measured both before and after a project. And half of all executives surveyed, whether IT or business executives, doubt that the measures are even accurate.Findings include:
At most companies, it's just guesswork.
Do CIOs measure business value often enough?
Only half do an ROI assessment both before and after an IT project is completed
Skepticism about ROI and business value metrics remains high.
Whether they measure in dollars or look at other forms of value, about half of respondents are skeptical about the accuracy of the numbers
IT executives exaggerate IT's impact on productivity.
Most IT executives believe technology's contribution to productivity is much higher than is indicated by economic indicators like the Bureau of Labor Statistics.

Security, systems development and web services do the best job of meeting or exceeding business value expectations; outsourcing, CRM and ERP fare worst.
