## three point estimates and quantitative risk analysis

Three-Point Estimate: Three-point estimate is applicable to both duration and cost estimates. The degree of uncertainty in each schedule activity and each line-item cost element is represented by a probability distribution. And how do we quantify risks? Risk analysis is an important concept in project management because as a project manager if you don’t know how to identify and evaluate factors that could affect the success of your project, you can not deal with them adequately. The link between qualitative and quantitative analysis is made explicit. Dr. Christian Smart (CCEA®) is the Chief Data Scientist with Galorath Federal. We discuss how to successfully implement them in the analysis of project risk. Risk Management Background. Consider using Quantitative Risk Analysis for: Quantitative Risk Analysis tools and techniques include but are not limited to: Let’s look at a simple Expected Monetary Value (EMV) example: Keep in mind that risks include both threats and opportunities. Opportunities are benefits that reduce cost. The project is divided into tasks (a work breakdown structure). The project success factors are determined 2. PERT applies a weighted average favoring the most likely outcome: (O + 4M + P)/6 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. Risks which might affect the project success factors are identified. The main difference between these two methods of risk analysis is that qualitative risk analysis uses a relative or descriptive scale to measure the probability of occurrence whereas quantitative risk analysis uses a numerical scale. Three point estimating can be done in two ways – one is by applying Beta Distribution technique, which uses PERT (Program Evaluation and Review Technique) formula and other is by applying Triangular Distribution technique, which calculates simple average. Why is Three Point Estimating Required? 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. This process is analyzes effect of risks on project objectives. It is performed to understand the probability and impact of risks on project objectives. Risks can be classified as positive or negative risks according to their impacts. It can be used along with decision tree analysis. Expected Monetary Value = Probability x Impact. The Monte Carlo Simulation is a quantitative risk analysis technique which is used to understand the impact of risk and uncertainty in project management. Optimistic. But there are occasions when you will benefit from a quantitative risk analysis. 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. PMBOK page 338. Risk analysis is broadly split into two areas (i.e., qualitative risk analysis, and 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. PMI-RMP: FREQUENTLY ASKED QUESTIONS FOR 2021, How To Improve Your Bottom Line Through Projects, The Curse of Project Management Knowledge, When to Perform Quantitative Risk Analysis. It can be used to overcome a range of problems in almost every field. The main purpose of conducting risk analysis is to determine the most appropriate strategies to deal with both positive and negative risks. Now the question is how do we perform a qualitative risk assessment? Quantitative Risk Assessment Tools & Techniques. Three-Point Estimates have a key role when it comes to the subject of Project Management. Calculates the effect of risk as a monetary value (cost) or number (duration). The following procedure is how it works, PMBOK-style. development of a worked example of a First Principles Risk Analysis (FPRA) model. Then we can evaluate the risks qualitatively and quantitatively. Discover where to start and what to study. During the life cycle of a project, team members encounter different types of risks. 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. And quantitative risk analysis produces statistical numbers for each of the risks, thus making it easier to prioritize them. Below are a few of them; In this risk analysis example, we will use the Expected Monetary Value technique to calculate the project risk exposure and the amount of Contingency Reserve. Are you thinking about taking the PMI-RMP® exam? QCRA. Failure Mode and Effects Analysis (FMEA): is the process of analyzing as many components as possible to determine potential failure modes in a system and their causes and effects. The Risk in this instance: Will I be able to eat? What is the Difference Between Qualitative and Quantitative Risk Analysis? Quantitative risk analysis focuses on numerically evaluating the influence of project risks on project elements. We discuss how to successfully implement them in the analysis of project risk.

The scale can be defined from low to high, from 1 … Make sure that you are including the right project baselines, subsidiary plans, and ancillary plans in your project management plans. There are many tools and techniques available to perform quantitative risk analysis. Business decisions are rarely made with all the information or data we desire. Three-point estimating is a tool that companies can use to help increase the accuracy of cost and time estimates. Quantitative risk analysis is an objective tool, that quantifies project risks which are usually prioritized during qualitative risk analysis. 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. Quantitative risk analysis starts with the model of the project, either its project schedule or its cost estimate depending on the objective. Project managers should be prepared to perform different types of risk analysis. 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. But they are far less than the long-range risks and costs of comfortable inaction. What happened? First, we identify risks. Considering critical business decisions, this tool provides more data and information than qualitative analysis. Quantitative risk analysis •Quantitative risk analyses have been evolving rapidly as the software tools and their integration with scheduling software packages have evolved. Decision Tree Analysis: A visual technique that supports decision making. Video Training . The team is encouraged to share their concerns and fears rather than hiding them into the buffered estimates. A project manager estimated a project's duration at eight months with a cost of $300,000. The key benefit of three point estimating is the way it takes into account project risk. The project manager did a Work Breakdown Structure (WBS) and estimated the work. Why should we perform it? Quantitative Risk Analysis – probability and consequences of risks. The following procedure is how it works, PMBOK-style. However they may also be used in connection with other important variables. The process generally follows qualitative analysis and utilizes techniques such as Monte Carlo simulation and decision analysis to: Determine the probability of achieving a specific project objective. Quantitative risk analysis is a numeric estimate of the overall effect of risk on the project objectives such as cost and schedule objectives. (adsbygoogle = window.adsbygoogle || []).push({}); Quantitative risk analysis focuses on numerically evaluating the influence of project risks on project elements. With the Risk Owner, conduct a quantitative analysis (3 point estimates) for each risk in the Program-Level Risk Set. 3. Risk Capability The greatest amount of effort and judgment goes into developing the three-point activity duration estimates to use in a schedule risk analysis. Quantitative Risk Assessment Tools and Techniques. Impacts are quantified with probability distributions that, in turn, produce probability distributions of results. This model gives us a result for the total time: 14 months. Meaning the management of risk focussed only on identifyin… 5. 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. 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)’. The project actually took twelve months and cost $380,000. Three Point Estimating. Qualitative Risk Analysis. The use of point estimates, averages, and qualitative methods all underestimate risk. 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). The process is performed at the beginning of the project and each iteration in an agile or hybrid life cycle (PMI, 2017). (Morgen Witzel, 2003). The Expected monetary value analysis (EMV) is an important concept in project risk management which is used for all... © 2018-2020 – ProjectCubicle Media. Program Evaluation and Review Technique (PERT) is another tool which uses estimation to complete quantitative risk analysis. Quantitative risk analysis starts with the model of the project, either its project schedule or its cost estimate depending on the objective. It provides detailed information regarding the probability and impact of a given risk. In this article, we explained their differences by focusing on quantitative risk analysis definition, tools and examples. It is difficult to perform this risk analysis for all project risks because of time constraints. Scales risks by using numbers (0-5) or percentages. Get My Risk Management Plan Template. Examples of three-point estimates for a cost estimate are shown in Figure 11-4. Let’s take a look at this type of analysis: What is it? The qualitative risk analysis process creates engagement opportunities for stakeholders. The use of point estimates, averages, and qualitative methods all underestimate risk. Like the name implies, there are three parts which are the three different estimates. The Monte Carlo Simulation is a quantitative risk analysis technique which is used to understand the impact of risk and uncertainty in project management. Quantitative Risk Analysis Quantitative risk analysis analyzes numerically the effect a project risk has on a project objective. It is performed to understand the probability and impact of risks on project objectives. Please try again. Success! In performing Qualitative-Risk-Analysis, PMs prioritize risks for action or additional analysis; Qualitative-Risk-Analysis is used to assess their probability of occurring and their likely impact (PMI, 2017). For instance, in a construction project, quantitative risk analysis helps us to calculate the impact of a project delay such as obtaining a permit late causes twenty day delay with a cost of $80,000. In project management, risk is any unexpected event that has the potential to affect the project goals – positive or negative. 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). 4. A risk can be defined in various aspects. It enables PMs to establish risk priorities and owners (PMI, 2017). 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. In this chapter, the methodology employed for the quantitative risk analysis that follows in Chapter 4 is explained. However, some of them have positive impacts. When should it be performed? Dr. Christian Smart (CCEA®) is the Chief Data Scientist with Galorath Federal. A project gets more transparency of threats and opportunities. From the very beginning: 1. Statistical Process Control Charting. ” John F. Kennedy. 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. Assume that you’re gathering cost estimates to determine whether a budget of $2.5 million is sufficient for a childcare center. Focuses on all the risks that have a possibility and high impact on the project elements. 4 “ There are risks and costs to a program of action. Actually, Contingency Reserve vs Management Reserve is an important topic... Risk Appetite vs Risk Tolerance vs Risk Threshold Risk Appetite vs Risk Tolerance vs Risk Threshold is one of... What is the importance of Decision Tree Analysis in project management? Once you've performed the Quantitative Risk Analysis, be sure to update your risk register with the additional risk information. Therefore, project managers should have enough knowledge of conducting different types of risk analysis. Context Three-point estimates are often made for the cost or schedule effects of project risk. The process often flows as the following; Below table summarizes the difference between these two risk analysis. Quantitative analysis is based on a simultaneous evaluation of the impact of all identified and quantified risks. It can be used to overcome a range of problems in almost every field. Note that quantitative and qualitative risk analysis is a significant concept for PMP or CAPM Certification Exams. Keep in mind: While the quantitative analysis is more objective, it is still an estimate. Notice we subtracted the benefit of the Opportunity from the EMV. Because PMP aspirants often get confused about how quantitative and qualitative risk analysis differs. However, in some cases, you need to conduct a perform quantitative risk analysis process to evaluate the risk. Just like any other estimation technique, 3-point estimation can be used for estimating duration or cost of a task (work … Each task receives three estimates: 1. Continuos probability distributions are usually used in quantitative risk analysis. For many projects, the quicker qualitative risk assessment is all you need. For simplicity, we will assume that each of these values is independent of others. Three-point estimates are often used as inputs to quantitative risk analysis. SWOT analysis. What do we need? If you want to add or share anything regarding the concept, please use the comments section below. This webinar will demonstrate how easy – and necessary – it is to implement quantitative risk analysis into a cost estimate. Monte Carlo simulation is a computerized mathematical technique that allows people to account for risk in quantitative analysis and decision making.

Large, complex projects that require Go/No Go decisions (the Go/No Go decision may occur multiple times in a project). Because quantitative risk analysis is associated with the schedule and cost objectives, focus on those estimates. Qualitative risk analysis is more subjective in nature, based on facts and figures from previous experience. • Introduction to Quantitative Analysis • Contingency Management • Questions. Quantitative Risk Analysis tools and techniques shall include but not limited to: Three-Point Estimate: A technique that uses the optimistic, most likely, and pessimistic values to make the best estimate possible. Threats have adverse impacts on cost. Projects where upper management wants more detail about the probability of completing the project on schedule and within budget. 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 the very beginning: The project success factors are determined; Risks which might affect the project success factors are identified. 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. – Best case no risks impact – expected case some risks impact – worst case all risks impact • Use lots of common sense 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. In this article, you will learn everything you need to know about qualitative risk analysis. What is Risk? Effort estimations are valuable though only if they are accurate. Most of the time, qualitative risk analysis provides you enough understanding of the characteristics of a given risk. It relies on three different estimates that are Optimistic, Pessimistic and Most Likely estimates. The certification names are the trademarks of their respective owners. Risk Monitoring and Control – monitoring and controlling the processes mentioned above. It helps project managers and business owners to make better duration and cost estimates. Explanation. 4. Sensitivity Analysis. Have you ever heard contingency budget in project management? 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. While the distribution used for the approximation might be a normal distribution, this is not always so and, for example a triangular distribution might be used, depending on the application. Module 11 of the PM PrepCast is all about Project Risk Management. 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. Three Point Estimating and Risk Analysis. This is an important point because, if the estimates are not correct, they will lead wrong decisions. In three-point estimation, … Analysis 19. Table-1 shows three-point estimates for five selected items in a project. Risk management process includes identification, evaluation, prioritization, and response.
