Management of risk
File:RiskManagement.jpeg From 2009 ISO 31000 defines risk as "the effect of uncertainty on objectives". Looking into that definition it is noted that the word risk does refer to positive possibilities as well as negative ones. This definition was revised under the ISO 31000:2009. Before revision the definition of the word "risk" was "chance or probability of loss". Meaning that only negative results could be associated with risk.
Management of risk involves identification, assessment, and prioritization of risks. Coordinated and economical application of resources to minimize, monitor, and control the probability and/or impact of unfortunate events or to maximize the realization of opportunities.
Among strategies used to manage threats are.
- Transferring the threat to another party
- Avoid the threat
- Reducing both the negative effect and lowering the probability of the threat
- Accepting the potential negative consequences of a particular thread is the only option.
- For uncertain events with benefits (opportunities) the opposite is done.
The term Risk management is really broad and can be used by individuals, families, firms, nations and so on. Events such as natural disasters are usually very hard to forecast but usually have large impacts. Whereas events such as minor human errors happen every day and are therefor relatively easy to forecast. Human errors can have from minor to major consequences. This displays the wide range of risk management well as each possible event has to be identified, assessed and prioritized.
In this article risk management in general will be outlined with a special focus on risk management activities as applied to project management. That is one aspect inside of risk management called Project risk management

Introduction
ISO Guide 73:2009, Risk management - Vocabulary complements ISO 31000. According to ISO 73:2009 risk management is intended to be used by those engaged in managing risks, those who are involved in activities of ISO and IEC, and developers of national or sector-specific standards, guides, procedures and codes of practice relating to the management of risk. [1]
Risks with great impacts and a high probability of happening are treated before risks with smaller impacts and lower possibility. This is called prioritization. There are several tools that can be used in the process of assessing risks. Those tools will be discussed in CHAPTER XX.
When allocating resources, risk management faces some difficulties. Short term planning would recommend skipping risk management when starting a new project as the process itself costs manpower and is not directly involved in the project itself. While long term thinking would definitely recommend going through the processes of risk management. That is because it could save a lot of money and even lives if it prevents one unfortunate event to happen as it was accounted for in the process. The effect of negative effects of risks is minimized as well as spending in ideal risk management.
Methodology
The following methods are a part of the general methodology, these methods are usually performed in the order as they are listed.
- identify and characterize threats
- assess the vulnerability of critical assets to specific threats
- determine the risk
- identify ways to reduce those risks
- prioritize risk reduction measures based on a strategy

Important principles
ISO has identified principles of risk management, some mentionable principles are.
- Create value
- Be part of decision making process
- Be a systematic and structured process
- Take human factors into account
- Be continually or periodically re-assessed

Benefits
The most notable potential benefits of a well-structured and efficiently run risk management are. [2]
- Improved strategic and business planning
- More effective use of resources
- An ability to quickly grasp new opportunities
- Fewer unwelcome surprises
- Enhanced communication
- Ability to reassure key stakeholders throughout the organization
- Continuous improvement
- robust contingency planning
Now it is time to take a deeper look at benefits of risk management for projects, portfolios and businesses.
For projects
Contingency in projects can make or break them. Too much contingency is uncompetitive and too little increases the chance of failure. Risk assessment helps set contingency levels. It aims to figure out the most probable level of risk and gives the confidence level of outcome targets.
For portfolios
For businesses
Project risk management
Qualitative
A pre-defined rating scale is used to prioritize the identified project risks. The probability or likelihood and the impact on a project objectives should they occur gives the score for a certain risk. A qualitative risk analysis also includes the appropriate categorization of the risks. Source-based or effect-based.
Quantitative
A further analysis of the highest priority risks during which a numerical or quantitative rating is assigned in order to develop a probabilistic analysis of the project. Possible outcomes for the project are quantified and the probability of achieving specific project objectives is assessed. When there is uncertainty a quantitative approach can be used to make decisions. It also creates realistic and achievable cost, schedule or scope targets.
Quantitative risk analysis can only be successfully carried out if there is high-quality data, a well-developed project model, and a prioritized lists of project risks. That usually yields from performing a qualitative risk analysis. [3]
| Qualitative | Quantitative |
|---|---|
| risk-level | project level |
| subjective evaluation of probability and impact | probabilistic estimates of time and cost |
| quick and easy to perform | time consuming |
| no special software or tools required | may require specalized tools |
Risk assessment
Risk assessment is the determination of quantitative or qualitative estimate of risk related to a concrete situation and a recognized hazard. Two components of risk are required for calculations in quantitative risk assessment. The magnitude of the potential loss (L) and the probability (p) that the loss will occur. If the countermeasure for handling a certain risk exceeds the value of the expected loss it is called acceptable risk. That kind of risk is understood and tolerated
