#11 PMP - Project Risk Management

#11 Project Risk Management


Project risk is an uncertain event or condition that, if it occurs, has a positive or negative effect on one or more project objectives such as scope, schedule, cost, and quality. A risk may have one or more causes and, if it occurs, it may have one or more impacts.
Project risk has its origins in the uncertainty present in all projects. Known risks are those that have been identified and analyzed, making it possible to plan responses for those risks. Known risks that cannot be managed proactively, should be assigned a contingency reserve. Unknown risks cannot be managed proactively and therefore may be assigned a management reserve. A negative project risk that has occurred is considered an issue.
Organizations perceive risk as the effect of uncertainty on projects and organizational objectives. Organizations and stakeholders are willing to accept varying degrees of risk depending on their risk attitude. The risk attitudes of both the organization and the stakeholders may be influenced by a number of factors, which are broadly classified into three themes:
-          Risk appetite, which is the degree of uncertainty an entity is willing to take on in anticipation of a reward.
-          Risk tolerance, which is the degree, amount, or volume of risk that an organization or individual will withstand.
-          Risk threshold, which refers to measures along the level of uncertainty or the level of impact at which a stakeholder may have a specific interest. Below that risk threshold, the organization will accept the risk. Above that risk threshold, the organization will not tolerate the risk.

Plan Risk Management
Plan Risk Management is the process of defining how to conduct risk management activities for a project. The key benefit of this process is it ensures that the degree, type, and visibility of risk management are commensurate with both the risks and the importance of the project to the organization. he inputs, tools and techniques, and outputs of this process are

Analytical techniques are used to understand and define the overall risk management context of the project. Risk management context is a combination of stakeholder risk attitudes and the strategic risk exposure of a given project based on the overall project context.
The risk management plan is a component of the project management plan and describes how risk management activities will be structured and performed. The risk management plan includes the following:
-          Methodology. Defines the approaches, tools, and data sources that will be used to perform risk management on the project.
-          Roles and responsibilities. Defines the lead, support, and risk management team members for each type of activity in the risk management plan, and clarifies their responsibilities.
-          Budgeting. Estimates funds needed, based on assigned resources, for inclusion in the cost baseline and establishes protocols for application of contingency and management reserves.
-          Timing. Defines when and how often the risk management processes will be performed throughout the project life cycle, establishes protocols for application of schedule contingency reserves, and establishes risk management activities for inclusion in the project schedule.
-          Risk categories. Provide a means for grouping potential causes of risk. Several approaches can be used, for example, a structure based on project objectives by category. A risk breakdown structure (RBS) helps the project team to look at many sources from which project risk may arise in a risk identification exercise.
-          Definitions of risk probability and impact. The quality and credibility of the risk analysis requires that different levels of risk probability and impact be defined that are specific to the project context.


-          Probability and impact matrix. A probability and impact matrix is a grid for mapping the probability of each risk occurrence and its impact on project objectives if that risk occurs. Risks are prioritized according to their potential implications for having an effect on the project’s objectives.
-          Revised stakeholders’ tolerances.
-          Reporting formats. Reporting formats define how the outcomes of the risk management process will be documented, analyzed, and communicated.
-          Tracking. Tracking documents how risk activities will be recorded for the benefit of the current project and how risk management processes will be audited.

Identify Risks
Identify Risks is the process of determining which risks may affect the project and documenting their characteristics. The key benefit of this process is the documentation of existing risks and the knowledge and ability it provides to the project team to anticipate events.

Participants in risk identification activities may include the following: project manager, project team members, risk management team (if assigned), customers, subject matter experts from outside the project team, end users, other project managers, stakeholders, and risk management experts. While these personnel are often key participants for risk identification, all project personnel should be encouraged to identify potential risks.
Information Gathering Techniques
Examples of information gathering techniques used in identifying risks can include:
-          Brainstorming. The goal of brainstorming is to obtain a comprehensive list of project risks.
-          Delphi technique. The Delphi technique is a way to reach a consensus of experts. Project risk experts participate in this technique anonymously. A facilitator uses a questionnaire to solicit ideas about the important project risks. The responses are summarized and are then recirculated to the experts for further comment. Consensus may be reached in a few rounds of this process. The Delphi technique helps reduce bias in the data and keeps any one person from having undue influence on the outcome
-          Interviewing. Interviewing experienced project participants, stakeholders, and subject matter experts helps to identify risks.
-          Root cause analysis. Root-cause analysis is a specific technique used to identify a problem, discover the underlying causes that lead to it, and develop preventive action.
Checklist Analysis. Risk identification checklists are developed based on historical information and knowledge that has been accumulated from previous similar projects and from other sources of information.
Diagramming Techniques Risk diagramming techniques may include:
-          Cause and effect diagrams. These are also known as Ishikawa or fishbone diagrams and are useful for identifying causes of risks.
-          System or process flow charts.
-          Influence diagrams. These are graphical representations of situations showing causal influences, time ordering of events, and other relationships among variables and outcomes.
SWOT Analysis. This technique examines the project from each of the strengths, weaknesses, opportunities, and threats (SWOT) perspectives to increase the breadth of identified risks by including internally generated risks.
Risk Register. The risk register is a document in which the results of risk analysis and risk response planning are recorded. The preparation of the risk register begins in the Identify Risks process with the following information, and then becomes available to other project management and risk management processes:
-          List of identified risks. The identified risks are described in as much detail as is reasonable.
-          List of potential responses. Potential responses to a risk may sometimes be identified during the Identify Risks process. These responses, if identified in this process, should be used as inputs to the Plan Risk Responses process.
Perform Qualitative Risk Analysis
Perform Qualitative Risk Analysis is the process of prioritizing risks for further analysis or action by assessing and combining their probability of occurrence and impact. The key benefit of this process is that it enables project managers to reduce the level of uncertainty and to focus on high-priority risks.

Risk probability assessment investigates the likelihood that each specific risk will occur.
Probability and Impact Matrix Risks can be prioritized for further quantitative analysis and planning risk responses based on their risk rating. Ratings are assigned to risks based on their assessed probability and impact. Evaluation of each risk’s importance and priority for attention is typically conducted using a look-up table or a probability and impact matrix.
Risk data quality assessment is a technique to evaluate the degree to which the data about risks is useful for risk management.
Risk Categorization. Risks to the project can be categorized by sources of risk (e.g., using the RBS), the area of the project affected (e.g., using the WBS), or other useful categories (e.g., project phase) to determine the areas of the project most exposed to the effects of uncertainty. Risks can also be categorized by common root causes.
Risk Urgency Assessment. Risks requiring near-term responses may be considered more urgent to address. Indicators of priority may include probability of detecting the risk, time to affect a risk response, symptoms and warning signs, and the risk rating


Perform Quantitative Risk Analysis
Perform Quantitative Risk Analysis is the process of numerically analyzing the effect of identified risks on overall project objectives. The key benefit of this process is that it produces quantitative risk information to support decision making in order to reduce project uncertainty.

Data Gathering and Representation Techniques.
-          Interviewing. Interviewing techniques draw on experience and historical data to quantify the probability and impact of risks on project objectives.
-          Probability distributions. Continuous probability distributions, which are used extensively in modeling and simulation, represent the uncertainty in values such as durations of schedule activities and costs of project components.


Quantitative Risk Analysis and Modeling Techniques
Commonly used techniques use both event-oriented and project-oriented analysis approaches, including:
-          Sensitivity analysis. Sensitivity analysis helps to determine which risks have the most potential impact on the project. One typical display of sensitivity analysis is the tornado diagram, which is useful for comparing relative importance and impact of variables that have a high degree of uncertainty to those that are more stable.
Example of Tornado Diagram:


-          Expected monetary value analysis. Expected monetary value (EMV) analysis is a statistical concept that calculates the average outcome when the future includes scenarios that may or may not happen (i.e., analysis under uncertainty). The EMV of opportunities are generally expressed as positive values, while those of threats are expressed as negative values. EMV requires a risk-neutral assumption— neither risk averse nor risk seeking. EMV for a project is calculated by multiplying the value of each possible outcome by its probability of occurrence and adding the products together. A common use of this type of analysis is a decision tree analysis.


-          Modeling and simulation. A project simulation uses a model that translates the specified detailed uncertainties of the project into their potential impact on project objectives. Simulations are typically performed using the Monte Carlo technique. In a simulation, the project model is computed many times (iterated), with the input values (e.g., cost estimates or activity durations) chosen at random for each iteration from the probability distributions of these variables. A histogram (e.g., total cost or completion date) is calculated from the iterations. For a cost risk analysis, a simulation uses cost estimates. For a schedule risk analysis, the schedule network diagram and duration estimates are used. The output from a cost risk simulation using the three-element model and risk ranges is shown in Figure. It illustrates the respective probability of achieving specific cost targets. Similar curves can be developed for other project objectives.

Project Documents Updates. Project documents are updated with information resulting from quantitative risk analysis. For example, risk register updates could include:
-          Probabilistic analysis of the project. Estimates are made of potential project schedule and cost outcomes listing the possible completion dates and costs with their associated confidence levels.
-          Probability of achieving cost and time objectives. With the risks facing the project, the probability of achieving project objectives under the current plan can be estimated using quantitative risk analysis results.
-          Prioritized list of quantified risks. This list includes those risks that pose the greatest threat or present the greatest opportunity to the project
-          Trends in quantitative risk analysis results. As the analysis is repeated, a trend may become apparent that leads to conclusions affecting risk responses.
Plan Risk Response
Plan Risk Responses is the process of developing options and actions to enhance opportunities and to reduce threats to project objectives. The key benefit of this process is that it addresses the risks by their priority, inserting resources and activities into the budget, schedule and project management plan as needed.

Strategies for Negative Risks or Threats. Three strategies, which typically deal with threats or risks that may have negative impacts on project objectives if they occur, are: avoid, transfer, and mitigate. The fourth strategy, accept, can be used for negative risks or threats as well as positive risks or opportunities. Avoidance and mitigation strategies are usually good strategies for critical risks with high impact, while transference and acceptance are usually good strategies for threats that are less critical and with low overall impact. The four strategies for dealing with negative risks or threats are further described as follows:
-          Avoid. Risk avoidance is a risk response strategy whereby the project team acts to eliminate the threat or protect the project from its impact. It usually involves changing the project management plan to eliminate the threat entirely. The project manager may also isolate the project objectives from the risk’s impact or change the objective that is in jeopardy.
-          Transfer. Risk transference is a risk response strategy whereby the project team shifts the impact of a threat to a third party, together with ownership of the response. Transferring the risk simply gives another party responsibility for its management—it does not eliminate it.
-          Mitigate. Risk mitigation is a risk response strategy whereby the project team acts to reduce the probability of occurrence or impact of a risk. It implies a reduction in the probability and/or impact of an adverse risk to be within acceptable threshold limits. Taking early action to reduce the probability and/or impact of a risk occurring on the project is often more effective than trying to repair the damage after the risk has occurred.
-          Accept. Risk acceptance is a risk response strategy whereby the project team decides to acknowledge the risk and not take any action unless the risk occurs. This strategy is adopted where it is not possible or cost-effective to address a specific risk in any other way.
Strategies for Positive Risks or Opportunities. Three of the four responses are suggested to deal with risks with potentially positive impacts on project objectives. The fourth strategy, accept, can be used for negative risks or threats as well as positive risks or opportunities. These strategies, described below, are to exploit, share, enhance, and accept.
-          Exploit. The exploit strategy may be selected for risks with positive impacts where the organization wishes to ensure that the opportunity is realized.
-          Enhance. The enhance strategy is used to increase the probability and/or the positive impacts of an opportunity.
-          Share. Sharing a positive risk involves allocating some or all of the ownership of the opportunity to a third party who is best able to capture the opportunity for the benefit of the project.
-          Accept. Accepting an opportunity is being willing to take advantage of the opportunity if it arises, but not actively pursuing it.
Control Risks
Control Risks is the process of implementing risk response plans, tracking identified risks, monitoring residual risks, identifying new risks, and evaluating risk process effectiveness throughout the project. The key benefit of this process is that it improves efficiency of the risk approach throughout the project life cycle to continuously optimize risk responses.
