Risk/ Benefit Ratio is an assessment of the risks against their benefit. Ideally the benefit has to outweigh risks in order for the company to accept the risk. Typically, risk analysis has a qualitative component and the result feeds into the assessment. According to PMBOK, there are several ways to approach how risks are assessed. Probabilistic analysis of the project are made of the potential project schedule and cost outcomes listing the possible completion dates and cost with their confidence levels. Probabilistic of achieving cost and timeline objectives with the risk facing the project, the probability of achieving the project objectives under the current plan using estimated qualitative risk analysis. Prioritized list of qualified risks includes those risks that may have the greatest effect on cost contingency and those that are most likely to influence the critical path (these risks may be evaluated in some cases through a tornado diagram). Trends in qualitative risk analysis results may become apparent that leads to conclusions affecting risk responses. The organization historical information on a project schedule, cost, quality, and performance should reflect new insights gained through qualitative risk analysis.
