The portfolio risk management enables you to create and manage an organization-wide risk register, develop a risk ranking for your portfolio of projects based on their risks and develop an organization wide mitigation plan.
Project Priorities and Risk Scores
In a well-balanced portfolio, different projects will have similar levels of risk. However, if the relative risk associated with a project is higher than similar projects, the project should be flagged for additional analysis. Alternatively, if project has less relative risk, it may represent an opportunity where additional cost or schedule risk could be transferred to it to mitigate higher risk projects in your portfolio.
