Comparative Decision Analysis-Economic Safety Margin (CDA-ESM): finally an alternative to the obsolete NPV.

Figure 1. For each analysis: min, max, average of the cumulative cost at forty years
We have included CDA/ESM in our Edumine Risk courses for mining for many years.
In 2010 we published the article (STOP PROCRASTINATING! NPV IS DEAD: USE RISK AS A KEY DECISION PARAMETER.) in the Canadian Reclamation. Indeed it showed two mining applications.
Is CDA/ESM more complex than NPV? Yes, of course! Like a motorcycle is more complex than a motorbike. The point here is that NPV will not take you anywhere safely. Indeed it is misleading, especially for long term projects like mining ones.
Riskope designed CDA/ESM with civil, mining, infrastructure projects in mind. Thus it is not a “financial world clonation” like the other available methods.
CDA/ESM will take you safely to the desired outcome, i.e a sound financial and risk based evaluation of your projects.
We have been very pleased to hear that, at last, some universities will put some Ph.D. Students investigating things we have spent money and effort researching.
