Source analysis  — Risk sources may be internal or external to the system that is the target of risk management use mitigation instead of management since by its own definition risk deals with factors of decision-making that cannot be managed. Examples of risk sources are: stakeholders of a project, employees of a company or the weather over an airport.
Problem analysis[ citation needed ] — Risks are related to identified threats. For example: the threat of losing money, the threat of abuse of confidential information or the threat of human errors, accidents and casualties. The threats may exist with various entities, most important with shareholders, customers and legislative bodies such as the government.
When either source or problem is known, the events that a source may trigger or the events that can lead to a problem can be investigated.
For example: stakeholders withdrawing during a project may endanger funding of the project; confidential information may be stolen by employees even within a closed network; lightning striking an aircraft during takeoff may make all people on board immediate casualties.
The chosen method of identifying risks may depend on culture, industry practice and compliance. The identification methods are formed by templates or the development of templates for identifying source, problem or event. Common risk identification methods are: Objectives-based risk identification[ citation needed ] — Organizations and project teams have objectives.
Any event that may prevent an objective from being achieved is identified as risk.
Scenario-based risk identification — In scenario analysis different scenarios are created. The scenarios may be the alternative ways to achieve an objective, or an analysis of the interaction of forces in, for example, a market or battle. Any event that triggers an undesired scenario alternative is identified as risk — see Futures Studies for methodology used by Futurists. Taxonomy-based risk identification — The taxonomy in taxonomy-based risk identification is a breakdown of possible risk sources.
Based on the taxonomy and knowledge of best practices, a questionnaire is compiled. The answers to the questions reveal risks. Each risk in the list can be checked for application to a particular situation. Creating a matrix under these headings enables a variety of approaches. One can begin with resources and consider the threats they are exposed to and the consequences of each.
Alternatively one can start with the threats and examine which resources they would affect, or one can begin with the consequences and determine which combination of threats and resources would be involved to bring them about. Main article: Risk assessment Once risks have been identified, they must then be assessed as to their potential severity of impact generally a negative impact, such as damage or loss and to the probability of occurrence.
Risk management - Wikipedia
These quantities can be either simple to measure, in the case of the value of a lost building, or impossible to know for sure in the case of an unlikely event, the probability of occurrence of which is unknown.
Therefore, in the assessment process it is critical to make the best educated decisions in order to properly prioritize the implementation of the risk management plan. Even a short-term positive improvement can have long-term negative impacts. Take the "turnpike" example.
A highway is widened to allow more traffic. More traffic capacity leads to greater development in the areas surrounding the metoda de gestionare a riscului de opțiune traffic capacity. Over time, traffic thereby increases to fill available capacity. Turnpikes thereby need to be expanded in a seemingly endless cycles.
There are many other engineering examples where expanded capacity to do any function is soon filled by increased demand. Since expansion comes at a cost, the resulting growth could become unsustainable without forecasting and management.
The fundamental difficulty in risk assessment is determining the rate of occurrence since statistical information is not available on all kinds of past incidents and is particularly scanty in the case of catastrophic events, simply because of their infrequency.
Furthermore, evaluating the severity of the consequences impact is often quite difficult for intangible assets. Asset valuation is another question that needs to be addressed. Thus, metoda de gestionare a riscului de opțiune educated opinions and available statistics are the primary sources of information.
Nevertheless, risk assessment should produce such information for senior executives of the organization that the primary risks are easy to understand and that the risk management decisions may be prioritized within overall company goals. Thus, there have been several theories and attempts to metoda de gestionare a riscului de opțiune risks. Numerous different risk formulae exist, but perhaps the most widely accepted formula for risk quantification is: "Rate or probability of occurrence multiplied by the impact of the event equals risk magnitude.
Periodically re-assess risks that are accepted in ongoing processes as a normal feature of business operations and modify mitigation measures. Transfer risks to an external agency e.
In business it is imperative to be able to present the findings of risk assessments in financial, market, or schedule terms. Robert Courtney Jr. IBM, proposed a formula for presenting risks in financial terms. The Courtney formula was accepted as the official risk analysis method for the US governmental agencies.
The formula proposes calculation of ALE annualized loss expectancy and compares the expected loss value to the security control implementation costs cost-benefit analysis. Potential risk treatments[ edit ] Once risks have been identified and assessed, all techniques to manage the risk fall into one or more of these four major categories:  Avoidance eliminate, withdraw from or not become involved Reduction optimize — mitigate Sharing transfer — outsource or insure Retention accept and budget Ideal use of these risk control strategies may not be possible.
Some of them may involve trade-offs that are not acceptable to the organization or person making the risk management decisions. Risk avoidance[ edit ] This includes not performing an activity that could present risk. Refusing to purchase a property or business to avoid legal liability is one such example. Avoiding airplane flights for fear of hijacking. Avoidance may seem like the answer to all risks, but avoiding risks also means losing out on the potential gain that accepting retaining the risk may have allowed.
Not entering a business to avoid the risk of loss also avoids the possibility of earning profits. Increasing risk regulation in hospitals has led to avoidance of treating higher risk conditions, in favor of patients presenting with lower risk. For example, sprinklers are designed to put out a fire to reduce the risk of loss by fire. This method may cause a greater loss by water damage and therefore may not be suitable.
Halon fire suppression systems may mitigate that risk, but the cost may be prohibitive as a strategy. Acknowledging that risks can be positive or negative, optimizing risks means finding a balance between negative risk and the benefit of the operation or activity; and between risk reduction and effort applied. By effectively applying Health, Safety and Environment HSE management standards, organizations can achieve tolerable levels of residual risk. Early methodologies suffered from the fact that they only delivered software in the final phase of development; any problems encountered in earlier phases meant costly rework and often jeopardized the whole project.

By developing in iterations, software projects can limit effort wasted to a single iteration. Outsourcing could be an example of risk sharing strategy if the outsourcer can demonstrate higher capability at managing or reducing risks.
This way, the company can concentrate more on business development without having to worry as much about the manufacturing process, managing the development team, or finding a physical location for a center. Risk sharing[ edit ] Briefly defined as "sharing with another party the burden of loss or the benefit of gain, from a risk, and the measures to reduce a risk.
In practice if the insurance company or contractor go bankrupt or end up in court, the original risk is likely to still revert to the first party. As such, in the terminology of practitioners and scholars alike, the purchase of an insurance contract is often described as a "transfer of risk.

For example, a personal injuries insurance policy does not transfer the risk of a car accident to the insurance company. The risk still lies with the policy holder namely the person who has been in the accident.
Methods of managing risk fall into multiple categories. Risk retention pools are technically retaining the risk for the group, but spreading it over the whole group involves transfer among individual members of the group.
This is different from traditional insurance, in that no premium is exchanged between members of the group up front, but instead losses are assessed to all members of the group.
Risk retention[ edit ] Risk retention involves accepting the loss, or benefit of gain, from a risk when the incident occurs. True self-insurance falls in this category.

Risk retention is a viable strategy for small risks where the cost of cele mai minime pariuri pe opțiuni binare against the risk would be greater over time than the total losses sustained. All risks that are not avoided or transferred are retained by default. This includes risks that are so large or catastrophic that either they cannot be insured against or the premiums would be infeasible.
War is an example since most property and risks are not insured against war, so the loss attributed to war is retained by the insured.
Also any amounts of potential loss risk over the amount insured is retained risk. This may also be acceptable if the chance of a very large loss is small or if the cost to insure for greater coverage amounts is so great that it would hinder the goals of the organization too much.

Risk management plan[ edit ] Main article: Risk management plan Select appropriate controls or countermeasures to mitigate each risk. Risk mitigation needs to be approved by the appropriate level of management. For instance, a risk concerning the image of the organization should have top management decision behind it whereas IT management would have the authority to decide on computer virus risks.
The risk management plan should propose applicable and effective security controls for managing the risks.

For example, an observed high risk of computer viruses could be mitigated by acquiring and implementing antivirus software. A good risk management plan should contain a schedule for control implementation and responsible persons for those actions. Mitigation of risks often means selection of security controlswhich should be documented in a Statement of Applicability, which identifies which particular control objectives and controls from the standard have been selected, and why.
Implementation[ edit ] Implementation follows all of the planned methods for mitigating the effect of the risks. Purchase insurance policies for the risks that it has been decided to transferred to an insurer, avoid all risks that can be avoided without sacrificing the entity's goals, reduce others, and retain the rest.
Review and evaluation of the plan[ edit ] Initial risk management plans will never be perfect.
