Quantitative cost risk analysis is a method used in project management to identify, assess, and prioritize potential risks that may affect the cost of a project. It involves using statistical data and mathematical models to analyze the probability and impact of potential cost risks and to estimate the potential cost of those risks. The ultimate goal of quantitative cost risk analysis is to provide project managers with the information they need to make informed decisions about how to mitigate or avoid the risks that could potentially have the greatest impact on the project's budget.

One of the key benefits of using quantitative cost risk analysis is that it allows project managers to identify and assess risks in a more systematic and objective manner. By using statistical data and mathematical models, project managers can better understand the probability and impact of different risks, which can help them prioritize the risks that need to be addressed first. This can be particularly useful when resources are limited, as it allows project managers to focus their efforts on the most important risks.

There are several different techniques that can be used in quantitative cost risk analysis, including statistical analysis, simulation modeling, and decision tree analysis. Each of these techniques has its own strengths and limitations, and the choice of technique will depend on the specific needs of the project and the data that is available.

One of the most common techniques used in quantitative cost risk analysis is statistical analysis, which involves using statistical tools and techniques to analyze the probability and impact of potential risks. This can be particularly useful for identifying trends and patterns in data, and can help project managers better understand the likelihood of different risks occurring.

Simulation modeling is another technique that is often used in quantitative cost risk analysis. This involves creating a computer model of the project and using it to simulate different scenarios and explore the potential consequences of different risks. This can be particularly useful for testing different strategies and identifying the most effective approach for mitigating or avoiding risks.

Decision tree analysis is another technique that is often used in quantitative cost risk analysis. This involves creating a tree-like diagram that shows the different decisions that need to be made and the potential consequences of those decisions. This can be particularly useful for helping project managers understand the trade-offs involved in different courses of action and for identifying the most cost-effective approach for mitigating or avoiding risks.

Overall, quantitative cost risk analysis is a valuable tool for project managers, as it allows them to identify and assess potential risks in a more systematic and objective manner. By using statistical data and mathematical models, project managers can better understand the probability and impact of different risks and make informed decisions about how to mitigate or avoid them. This can help ensure that projects stay within budget and are completed on time, which is crucial for the success of any project.

Then project team need to develop risk action plan including specific mitigation plan, associated timing and resources and assign risk owner to all prioritized high level impact risks. The safety level is better determined grounded on the three basics: accessibility, veracity, and privacy. Although most systems are operated under changing conditions, conventional methods use reliability models with constant parameters only, and thus average operating conditions should be applied. In addition, if such an employee is assigned to work in the United States, a similar challenge can arise. Some of the countries have codified this requirement into law. Quantitative Risk Analysis in Project Management Quantitative risk analysis in project management is the process of altering the effect of risk on the project into arithmetical terms. Why Perform Quantitative Risk Analysis Better Overall Project Risk Analysis Individual risks are evaluated in the qualitative risk analysis.

## Quantitative Cost Risk Assessment

The estimation and calculation of probable threats, susceptibilities, and possible harm are very important. Quantitative analysis is about assigning monetary values to risk components. As their names imply, each approaches the same data in a different way. But for the reasons stated below, this led to duplication of effort updates to multiple systems and time consuming use of resources. Over time the range between the P50, P80 and P95 values have been reducing, as is to be expected on a project on the scale of Crossrail. A more streamlined system could have been considered from the outset. Qualitative risk analysis does not assign numerical values but instead opts for general categorization by severity levels.

. In line with mitigation plan progress, we expect that several risks and uncertainties impacts already have been reduced. You can do a separate analysis using worst-case values if you believe that would be helpful. The next step, we will determine uncertainties range of each cost element scope and rate and the result is as shown in Table 4. Berrong 2010: 48—50 writes that, because many organizations operate globally, finding a security fit in each country can be tricky.

It reduces the project likelihood to achieve objectives with baseline cost and schedule is reduced and more contingency is needed to cover identified risks and uncertainties. The outcomes offer an understanding of the probability of project accomplishment and are used to advance contingency reserves. This phenomenon shows that the real decision to build was taken much earlier in the decision-making process. There can be significant differences between the two systems for several reasons — I.

Basis of estimates— this will tell you how estimates were created and the less scientific ways of developing estimates will represent a higher risk to the project. Risk Mitigation Since not all risks have high critical level impact to project outcome, project team need to prioritize all analyzed risks.

Quantitative-quantity is a hint to remember this for the exam. Quantitative risk analysis is a proven technique that can help to combat risks. Once schedule model is developed, the next step is determining the uncertainties range of each schedule task. Utilizing triangular probability distribution function, the determined range will be iterated in Monte Carlo simulation to generate S-Curve. If anything, Quantitative risk analysis must be steered simultaneously, giving you the best probable intuition into risks and their possible effect on the fruitful accomplishment of your project. What documents should you review? In brief, the consequences analysis implies quantification of the amount of material released, dispersion calculations, characterization of the scenario, and finally quantification of consequences. This simulation result communicates potential risks and allows the management to select appropriate risk contingency level based on company approach.

There are many well-known mega-projects with major cost overruns. For many projects, the quicker qualitative risk assessment is all you need. Stage 1—Identify scenario components Step 1—Identify the asset s at risk In order to estimate the control and value characteristics within a risk analysis, the analyst must first identify the asset object under evaluation. Poor quality analysis leads to inaccurate decision making. If the control is cost effective relative to the exposure of the organization, then the control is put in place. Those situations and conditions are defined as project risks and uncertainties. During project execution phase, naturally, there are a lot of situations and conditions which were not predicted and potentially impact to project performances especially for cost and schedule.

## Evaluating Risks Using Quantitative Risk Analysis

As mentioned above, quantitative cost and schedule risk analysis utilizes Monte Carlo simulation. This method generates an analysis of the risks facing an organization and is based on experience, judgment, and intuition. Project risk management is most effective if it is monitored, controlled and adjusted if required. As mentioned previously, quantitative cost and schedule risk analysis should be conducted periodically. Effective combination of those requirements will guide the entire project team to carry out outstanding performance in achieving project objectives.
