This article is an overview and summary of relevant body of knowledge concerning risk management in project portfolios. Project portfolio management (PPM) is the set of managerial activities that are required to manage a collection of projects and programs needed to achieve stratetic business objectives.[1] It has been widely accepted that Risk Management is an important part of Project Management. Project risk management enables an organisation to limit the negative impact of uncertain events and/or to reduce the probability of these negative events materialising, while simultaneously aiming to capture opportunities [2]. However, project risk management is only effective to a limited extent because it lacks a portfolio wide view. [3] The information available regarding risk management at portfolio level is fairly scarce. Methods like Monte Carlo Simulations can be used to create efficient frontier charts in order to best as possible choose risk/return balance within the portfolio. Numerical methods are however often associated only with risks (known unkowns) and not uncertanties (unknown unknowns).

Project Portfolio Uncertainty Dimensions
The uncertainties at the portfolio level can be found within three dimensions[4]: Uncertainty from organizational complexity, from environment, and from single projects.
The uncertainty from organizational complexity may stem from the system being used to manage the portfolio, the projects' relationshops with the parent organization, interdependencies between projects, and other managerial features specific to the organization in question. The degree of the uncertainties based in complexity, is of course dependent on the degree to which autonomy is experienced and gained from the parent organization.[4] External uncertainties include a more complex business context in the assessment of uncertainty. The mindset is that, if broader project and business networks have an effect on single projects and their management, they will eventually impact project portfolios too. It has been shown that market and technology turbulence, and external dynamics have been discovered as relevant in mediating or moderating the relationship between certain project portfolio management dimensions and project portfolio success.[4] The uncertainty derived from single projects are relevant for portfolios due to changes, deviations and unexpected events. The dependencies between projects mean that single projects might affect the entire portfolio of projects. In general it can be said that changes in single projects are reflected on changes in other projects and the portfolio as a whole.[4]
The below table contains findings related to the three different dimensions of uncertainty.

Project Portfolio Succes
Project portfolio succes is defined on six parameters: Average project success, average product success, strategic fit, portfolio balancing, preparing for the future and economic success.[3] Combined these parameters give portfolio managers a way to assess the overall succes of a specific project portfolio.
- Average project success
- Level of success regarding the iron triangle (cost, quality and time). Also includes the compliance with the fulfillment of the defined specifications of all projects in the portfolio
- Average product succes
- Level of success of all projects in the portfolio. This includes both market and commercial success.
- Strategic fit
- To which extent the projects in the portfolio reflects the corporate business.
- Portfolio balancing
- The equilibrium between high-risk and low-risk projects, long-term and short-term projects, and technologies and markets.
- Preparing for the future
- The ability to quickly react to changes in the environment and seize opportunities in the long term.
- Economic success
- Adresses the overall market succes and commercial success of an organization or business unit.
Correlations between Risk Management and Project Portfolio Success
With the above understanding of project portfolio success, it has been possible to examine correlations between the use of risk management and project portfolio success. Teller et al.[3] concludes the following points through their investigation of project portfolios:
- Formal project risk management is positively related to project portfolio success
- The integration of risk information into project portfolio management is positively related to project portfolio success
- The simultaneous use of a formal project risk management process and the integration of risk information into project portfolio management increase the positive effect on project portfolio success (positive interaction effect)
- The relationship between formal project risk management and project portfolio success is stronger in portfolios with an R&D focus
- The relationship between the integration of risk information into project portfolio management and project portfolio success becomes stronger as external turbulence increases
- The relationshop between formal project risk management and project portfolio success becomes stronger with increasing portfolio dynamics
