Quantitative risk assessment requires calculations of two components of risk (R):, the magnitude of the potential loss (L), and the probability (p) that the loss will occur. Single value 1-point estimate More knowledge / less uncertainty Beta Pert (larger shape parameter, default shape parameter of 4) 3-point estimate Triangle / Trigen 3-point estimate Beta Pert (smaller shape parameter) 3-point estimate Uniform 2-point estimate Less knowledge / more uncertainty Credit: from Centrica Energy’s QRA training manual Quantitative risk analysis makes use of a single factor produced from these elements – called the ‘Annual Loss Expectancy (ALE)’ or the ‘Estimated Annual Cost (EAC)’. – Best case no risks impact – expected case some risks impact – worst case all risks impact • Use lots of common sense Program Evaluation and Review Technique (PERT) is another tool which uses estimation to complete quantitative risk analysis. The project actually took twelve months and cost $380,000. Considering critical business decisions, this tool provides more data and information than qualitative analysis. But there are occasions when you will benefit from a quantitative risk analysis. Quantitative Risk Analysis by contrast is about estimating the effect of uncertainty in the various estimates used in creating a project schedule. Please try again. In the project scheduling context, Quantitative Risk Analysis generally means using Monte Carlo Simulation based upon a project network. PERT applies a weighted average favoring the most likely outcome: (O + 4M + P)/6 Quantitative risk analysis in general involves statistical technique called Monte Carlo simulation. Large, complex projects that require Go/No Go decisions (the Go/No Go decision may occur multiple times in a project). development of a worked example of a First Principles Risk Analysis (FPRA) model. Why is Three Point Estimating Required? Histograms. This estimate is going to be more accurate than you will get if you hope that one of the possibilities will be the one that actually takes place. Distributions represent both probability and consequences of the project component. Quantitative risk analysis •Quantitative risk analyses have been evolving rapidly as the software tools and their integration with scheduling software packages have evolved. Examples of three-point estimates for a cost estimate are shown in Figure 11-4.

Projects that require a Contingency Reserve for the schedule and budget. Identify risks requiring the most attention by quantifying their Project managers should be prepared to perform different types of risk analysis. It’s possible to rank events by order of risk (ALE) and to make decisions based upon the ALE. It's also important not to create estimates that are too broad, and assume you can use the analysis to narrow the probabilities. The scale can be defined from low to high, from 1 … For example, on an aircraft development project, design-related risks might be assessed in terms of their effect on weight. The use of quantitative methods for risk analysis is well established. It is performed to understand the probability and impact of risks on project objectives. Therefore, project managers should have enough knowledge of conducting different types of risk analysis. The use of point estimates, averages, and qualitative methods all underestimate risk. In project management, risk is any unexpected event that has the potential to affect the project goals – positive or negative. Three Point Estimating. Qualitative Risk Analysis. If you want to add or share anything regarding the concept, please use the comments section below. Context Three-point estimates are often made for the cost or schedule effects of project risk. Quantitative Risk Analysis – probability and consequences of risks. For QRA, for methods using probability x impact in some manner, the most meaningful definitions for risk and uncertainty are (note: these are not in RP 10S-90 and readers should monitor terminology development): Table-1 shows three-point estimates for five selected items in a project. This is an important point because, if the estimates are not correct, they will lead wrong decisions. From there you can do quantitative analysis with 3 points estimate for probability and cost or schedule. Remember: The Impact used in EMV is in days or dollars. Three-point estimates are based on determining three types of estimates: • Most likely. Task Time Estimate Job 1 5 Months Job 2 4 Months Job 3 5 Months Total 14 Months Table 1: Basic Forecasting Model In the simplest case, we create a single estimate for each of the three parts of the project. It helps project managers and business owners to make better duration and cost estimates. However, the project manager failed to consider the potential impact of the risks (good and bad) on the schedule and budget. The team is encouraged to share their concerns and fears rather than hiding them into the buffered estimates. TCM 3.3 - Investment Decision Making: Decision analysis of alternatives in consideration of risk as covered by TCM 3.3 is a separate topic. The three-point estimation technique is used in management and information systems applications for the construction of an approximate probability distribution representing the outcome of future events, based on very limited information. The Risk in this instance: Will I be able to eat? It is used to model the probability of various outcomes in a project (or process) that cannot easily be estimated because of the intervention of random variables. Click here to see an example. Assume that you’re gathering cost estimates to determine whether a budget of $2.5 million is sufficient for a childcare center. Sensitivity Analysis. Residual Risks vs Secondary Risks Residual Risks vs Secondary Risks – We face risks in our daily lives. Risks can influence resources, deliverables, processes and objectives of a project. Qualitative Risk -The method of prioritizing individual project risks for further analysis or action by assessing their probability of existence and impact as well as other characteristics. That is why the risk that is involved with that original assessment has to be calculated into the overall projection. The process is performed at the beginning of the project and each iteration in an agile or hybrid life cycle (PMI, 2017). Quantitative Analysis: Getting the Three Point Estimates • NOW, interview risk/task managers • Work with the impact table • Determine three point estimates. In qualitative risk analysis, impacts and likelihood ev… Hybrid risk analysis combines the two by using quantitative analysis for risks that may be easily expressed in hard numbers, such as money, and qualitative analysis for the remainder. PERT is a particular type of 3 point estimation, where the Most Likely estimate is weighted 4 times the optimistic or pessimistic estimates. I'd like to receive the free email course. Risk Management Background. The Monte Carlo Simulation is a quantitative risk analysis technique which is used to understand the impact of risk and uncertainty in project management. Have you ever heard contingency budget in project management? Are you thinking about taking the PMI-RMP® exam? Risk analysis is broadly split into two areas (i.e., qualitative risk analysis, and quantitative risk analysis). Risk Capability Analysis 19. Decision analysis involves more inputs than the capital cost and schedule risks covered by the QRA methods in this RP (e.g., must consider revenue and opex as well as capex in NPV analysis). Risk management process includes identification, evaluation, prioritization, and response. But the quantitative analysis allows us to evaluate the overall project risk from the individual risks plus other sources of risks. But they are far less than the long-range risks and costs of comfortable inaction. With the Risk Owner, conduct a quantitative analysis (3 point estimates) for each risk in the Program-Level Risk Set. When should it be performed? The Risk Driver approach focuses on the risks themselves, usually derived from the Risk Register that uses qualitative risk analysis methods to prioritize individual risks. At this point, note that both methodologies will be applied to two construction projects, as part of the quantitative risk analysis that follows in Chapter 4. Three-point estimating is a tool that companies can use to help increase the accuracy of cost and time estimates. Of these two, qualitative risk analysis is most common, and on many projects, it is the only risk analysis that is done. Project Risk Management Handbook 13 Quantitative Risk Analysis Quantitative Risk Analysis Quantitative risk analysis is a way of numerically estimating the probability that a project will meet its cost and time objectives. Qualitative risk analysis requires that the probability and consequences of the risk be evaluated using established qualitative-analysis methods and tools, describing them in terms such as very high, high, moderate, low, very low. Impacts are quantified with probability distributions that, in turn, produce probability distributions of results. Quantitative Risk Analysis tools and techniques include but are not limited to: Three Point Estimate – a technique that uses the optimistic, most likely, and pessimistic values to determine the best estimate. Because quantitative risk analysis is associated with the schedule and cost objectives, focus on those estimates. The technique is used by professionals in such widely disparate fields as finance, project management, energy, manufacturing, engineering, research and development, insurance, oil & gas, transportation, and the environment. These two dimensions of risk are applied to each specific risk event and the results may be plotted using a probability-impact matrix. It is a financial model that identifies how target variables are affected based on changes in other variables. Individual risks are evaluated in the qualitative risk analysis. It is often applied to large and complex projects, Expected Monetary Value (Probability x Impact), Scaling project risks by using qualitative risk analysis, Performing quantitative risk analysis for the critical risks, If your project requires Contingency Reserve to manage schedule and budget risks, If your project is large and sophisticated and you need better decisions, If you need more accurate and objective risk analysis for a given risk. 5. For simplicity, we will assume that each of these values is independent of others. It is used along with three-point estimates. The second question Seem what your doing is limited to a schedule risk analysis using Monte Carlo, Palisade @Risk use to have a macro that would do the Monte Carlo on MS project files, not sure if still available. First, we identify risks. QCRA The purpose of a Quantitative Cost Risk Analysis (QCRA) is to estimate an appropriate level of cost contingency to supplement the project estimate and provide confidence that the budgetary allowance will not be surpassed. For more critical decisions, quantitative risk analysis provides more objective information and data than the qualitative analysis. Quantitative risk assessments (QRAs) on projects are less common, often because insufficient data about the project are available to perform the assessment. The present paper addresses this issue and shows how a certain qualitative risk assessment approach can be applied in conjunction with FRAM. At that stage, however, risk management techniques were all still largely qualitative. In this chapter, the methodology employed for the quantitative risk analysis that follows in Chapter 4 is explained. If you are preparing for your PMI PMP Certification Exam, you need to understand the basics of quantitative risk analysis definitions, tools, and examples. From this aspect, it supports decision making. A project manager estimated a project's duration at eight months with a cost of $300,000. PMBOK page 338. The likely impact of a risk may be expressed as a 3 -point estimate (minimum, most likely, maximum) or a 2-point estimate (minimum to maximum). The risks are analyzed and prioritized to determine which are the most important. In this eBook, you will discover how to create a project charter, step-by-step. Risks can be classified as positive or negative risks according to their impacts. All Rights Reserved. Calculates the effect of risk as a monetary value (cost) or number (duration). Expected Monetary Value: A statistical technique that helps to compare and evaluate risks. Monte Carlo Analysis: Monte Carlo Analysis is performed to model the probability of various outcomes in a process that can’t handily be estimated because of the intervention of random variables. There was an error submitting your subscription. In single point estimating, a single value of task estimate is determined, which can be fairly inaccurate for the complex tasks. Then we can evaluate the risks qualitatively and quantitatively. 4. The calculation for an event is done by multiplying the potential loss by the probability. And quantitative risk analysis produces statistical numbers for each of the risks, thus making it easier to prioritize them. The link between qualitative and quantitative analysis is made explicit. Three-Point Estimate: Three-point estimate is applicable to both duration and cost estimates. It is performed to understand the probability and impact of risks on project objectives. Quantitative risk analysis • The risk model shows the effect of the risk assessment, on the overall project Base estimate (MMUSD) Bulks 2.3 Fabrication 5.7 Transportation 1.9 Heavy lift vessel 1.6 Hook-up and commissioning 4.3 Project services 0.6 Total 16.4 The P90 is a "reasonably likely" worst case. Opportunities are benefits that reduce cost. The three-point estimation technique is used in management and information systems applications for the construction of an approximate probability distribution representing the outcome of future events, based on very limited information. 4. The qualitative risk analysis process creates engagement opportunities for stakeholders. It enables PMs to establish risk priorities and owners (PMI, 2017). Risk management (in its very loosest form) can be traced back to the beginning of human origins, but it was only towards the end of the 19th century, when high-rise buildings, complex railway infrastructures, large dams and canals started being built, that formalised project risk management techniques became more widespread in helping determine the outcome of a project. As an example, if a developer estimates that his part of the code would need 5 days optimistically, 10 days most likely, and 30 days pessimistically, then the three-point estimate would be (5 + 4*10 + 30)/6 = 12,5 days. It is used to model the probability of various outcomes in a project (or process) that cannot easily be estimated because of the intervention of random variables.
