The ROI that I have achieved was approximately $300k in the first year.

Since we are a high risk environment, we have calculated that any core business down time will cost us ~$18K per minute (or ~$1M per hour, with our core business process’s reset time projected at ~9 hours = ~$9M or more). Similarly, any efficiencies gained will be realized at those same rates (~$18K per minute, etc.). As a result, we are expecting that our select BI solution will pay for itself many times over in both disasters averted and efficiencies gained through our core business’s continuous process improvement efforts.

Not sure if management has performed any analysis for  ROI.

More than 80%.

Yes, still learning.
