    The Importance of Project Risk

    Management Project risk management is the art and science of

    identifying, assigning, and responding to riskthroughout the life of a project and in the best interestsof meeting project objectives

    Risk management is often overlooked on projects, butit can help improve project success by helping selectgood projects, determining project scope, anddeveloping realistic estimates

    A study by Ibbs and Kwak show how risk managementis neglected, especially on IT projects

    KPMG study found that 55 percent of runaway projectsdid no risk management at all

    What is Risk?

    A dictionary definition of risk is thepossibility of loss or injury

    Project risk involves understandingpotential problems that might occur on theproject and how they might impede projectsuccess

    Risk management is like a form ofinsurance; it is an investment

    Risk Utility

    Risk utility or risk tolerance is the amount ofsatisfaction or pleasure received from a

    potential payoff

    Utility rises at a decreasing rate for a person whois risk-averse

    Those who are risk-seeking have a highertolerance for risk and their satisfaction increaseswhen more payoff is at stake

    The risk-neutral approach achieves a balance

    between risk and payoff

    What is Project Risk Management?

    The goal of project risk management is to minimize potential risks

    while maximizing potential opportunities. Major processes include Risk management planning: deciding how to approach and plan

    the risk management activities for the project

    Risk identification: determining which risks are likely to affect aproject and documenting their characteristics

    Qualitative risk analysis: characterizing and analyzing risks andprioritizing their effects on project objectives

    Quantitative risk analysis: measuring the probability andconsequences of risks

    Risk response planning: taking steps to enhance opportunitiesand reduce threats to meeting project objectives

    Risk monitoring and control: monitoring known risks,identifying new risks, reducing risks, and evaluating theeffectiveness of risk reduction

    10

    Risk Management Planning

    The main output of risk management planning is

    a risk management plan

    The project team should review project

    documents and understand the organizations

    and the sponsors approach to risk

    The level of detail will vary with the needs of

    the project

    Contingency and Fallback Plans,

    Contingency Reserves

    Contingency plans are predefined actions thatthe project team will take if an identified riskevent occurs

    Fallback plans are developed for risks that havea high impact on meeting project objectives

    Contingency reserves or allowances are

    provisions held by the project sponsor that canbe used to mitigate cost or schedule risk ifchanges in scope or quality occur

    Common Sources of Risk on

    Information Technology Projects

    Several studies show that IT projects share some

    common sources of risk

    The Standish Group developed an IT success

    potential scoring sheet based on potential risks

    McFarlan developed a risk questionnaire to help

    assess risk

    Other broad categories of risk help identify

    potential risks

    Other Categories of Risk Market risk: Will the new product be useful to

    the organization or marketable to others? Will

    users accept and use the product or service?

    Financial risk: Can the organization afford to

    undertake the project? Is this project the best

    way to use the companys financial resources?

    Technology risk: Is the project technicallyfeasible? Could the technology be obsolete

    before a useful product can be produced?

    What Went Wrong?

    Many information technology projects fail because of technology risk. Oneproject manager learned an important lesson on a large IT project: focus on

    business needs first, not technology. David Anderson, a project manager for

    Kaman Sciences Corp., shared his experience from a project failure in an article

    for CIO Enterprise Magazine. After spending two years and several hundred

    thousand dollars on a project to provide new client/server-based financial and

    human resources information systems for their company, Anderson and his

    team finally admitted they had a failure on their hands. Anderson revealed that

    he had been too enamored of the use of cutting-edge technology and had taken

    a high-risk approach on the project. He "ramrodded through" what the project

    team was going to do and then admitted that he was wrong. The company

    finally decided to switch to a more stable technology to meet the business needs

    of the company.

    Expert Judgment

    Many organizations rely on the intuitive feelings

    and past experience of experts to help identify

    potential project risks

    Experts can categorize risks as high, medium, or

    low with or without more sophisticated

    techniques

    Quantitative Risk Analysis

    Often follows qualitative risk analysis, but both

    can be done together or separately

    Large, complex projects involving leading edge

    technologies often require extensive quantitative

    risk analysis

    Main techniques include

    decision tree analysis

    simulation

    28

    Decision Trees and Expected Monetary

    Value (EMV)

    A decision tree is a diagramming method used

    to help you select the best course of action in

    situations in which future outcomes are

    uncertain

    EMV is a type of decision tree where you

    calculate the expected monetary value of a

    decision based on its risk event probability and

    monetary value

    30

    Simulation Simulation uses a representation or model of a

    system to analyze the expected behavior orperformance of the system

    Monte Carlo analysis simulates a modelsoutcome many times to provide a statisticaldistribution of the calculated results

    To use a Monte Carlo simulation, you must

    have three estimates (most likely, pessimistic,and optimistic) plus an estimate of thelikelihood of the estimate being between theoptimistic and most likely values

    What Went Right?A large aerospace company used Monte Carlo simulation to help quantify

    risks on several advanced-design engineering projects. The NationalAerospace Plan (NASP) project involved many risks. The purpose of this

    multibillion-dollar project was to design and develop a vehicle that could

    fly into space using a single-stage-to-orbit approach. A single-stage-to-orbit

    approach meant the vehicle would have to achieve a speed of Mach 25 (25

    times the speed of sound) without a rocket booster. A team of engineers and

    business professionals worked together in the mid-1980s to develop a

    software model for estimating the time and cost of developing the NASP.

    This model was then linked with Monte Carlo simulation software to

    determine the sources of cost and schedule risk for the project. The results

    of the simulation were then used to determine how the company would

    invest its internal research and development funds. Although the NASP

    project was terminated, the resulting research has helped develop more

    advanced materials and propulsion systems used on many modern aircraft.

    32

    Risk Response Planning After identifying and quantifying risks, you

    must decide how to respond to them

    Four main strategies:

    Risk avoidance: eliminating a specific threat or risk,usually by eliminating its causes

    Risk acceptance: accepting the consequences shoulda risk occur

    Risk transference: shifting the consequence of a riskand responsibility for its management to a thirdparty

    Risk mitigation: reducing the impact of a risk eventby reducing the probability of its occurrence

    Risk Monitoring and Control

    Monitoring risks involves knowing their status

    Controlling risks involves carrying out the riskmanagement plans as risks occur

    Workarounds are unplanned responses to riskevents that must be done when there are nocontingency plans

    The main outputs of risk monitoring and controlare corrective action, project change requests,and updates to other plans

  • 8/10/2019 6 Project Risk Management Kathys

    18/20

    35

    Risk Response Control

    Risk response control involves executing the riskmanagement processes and the risk management

    plan to respond to risk events

    Risks must be monitored based on defined

    milestones and decisions made regarding risks

    and mitigation strategies

    Sometimes workarounds or unplanned responses

    to risk events are needed when there are nocontingency plans

    36

    Using Software to Assist in Project

    Risk Management

    Databases can keep track of risks. Many IT

    departments have issue tracking databases

    Spreadsheets can aid in tracking and quantifying

    risks

    More sophisticated risk management software,

    such as Monte Carlo simulation tools, help in

    analyzing project risks

    Results of Good Project Risk

    Management

    Unlike crisis management, good project risk

    management often goes unnoticed

    Well-run projects appear to be almost effortless,

    but a lot of work goes into running a project

    well

    Project managers should strive to make their

    jobs look easy to reflect the results of well-run

    projects
