Well to me, this means – the results of the risk analysis has to be presented in EXACTLY the same way the decision is being discussed.
If an investment decision is made based on NPV and IRR – then risk manager has to bring to the table new calculation for NPV and IRR based on risk analysis.
If the decision is discussed in terms of schedule and budget – the risk manager needs to calculate and bring new schedule and budget with risks incorporated.
