They are Standard Operating Tools for risk management as prescribed by the Project Manage- ment Institute (PMI), International Council on Systems Engineering (INCOSE), and many other organizations. They are widely used in projects and programs structured for product development, business, construction, R & D, medicine, and politics. However, they suffer from several weaknesses, notably subjectivity, symmetry, category prioritization reversal, and a failure to account for Risk Aversion, which often dominates how individuals and companies feel about risk.

Because of this, they can lead to serious mis-prioritization and mismanagement of risks. We propose an alternative to the standard risk matrix that accounts for these deficiencies and provides a significantly better risk prioritization tool. Two field trials were conducted to demonstrate the benefits of the alternative method for project managers.

1. Risk Identification 2. Risk Assessment/Analysis 3. Risk Prioritization 4. Risk Response Planning 5. Risk Monitoring Each step is challenging, but all are important in the proper management of project risks. This paper addresses Step 3 (Risk Prioritization) only, assuming that project risks have already been identified and assessed with respect to probability (or likelihood) and impact.

Risk matrices (also known as “probability and impact matrices” or “Risk Heat Maps”) are two-dimensional arrays that typically list risk impact on the abscissa and risk probability on the ordinate (Project Management Institute, 2008; Cox, 2008; INCOSE, 2011; Alleman, 2010).

They are often used to prioritize risks. A typical risk matrix is depicted in Figure 1. 1. They are qualitative and subjective, and definitions of “high”, “medium,” and “low” may mean different things to dif- ferent people.

2. They are typically presented as symmetric about the diago- nal, which is often invalid.

3.

They do not account for risk aversion, which is manifested by almost every entity in making decisions.

4. The breadth of the categories may result in serious prioriti- zation errors.

These flaws have been demonstrated and well-documented. Many researchers (Hubbard, 2009; Ball & Watt, 2013; Cox, 2008; Duijm, 2015; Aven, 2017; Wall, 2011) note the subjectivity associated with assigning both probabilities and impacts. Hubbard (2009) calls the use of risk matrices “borderline or worthless” and Cox (2009) calls it “worse than useless.” Wall says that “their theoretical basis is su- perficial and the validity of the qualitative information they employ is highly suspect.” Duijm agrees with Cox but makes several recom- mendations for Risk Matrix use and design because “attempting to curtail their use will be futile.” Ball and Watt also agree with Cox in that “there simply may be no right way to fill in these matrices” and go on to state that they belie a spurious simplicity. Bahill and Smith (2009) list 9 flaws associated with Risk Matrices. Oboni and Oboni (2013) claim that “[Risk Matrices] can be misleading, and expose organizations to potential litigation,” and also that they “have a number of staggering intrinsic conceptual errors, with potentially dramatic negative consequences on their users.” Pickering and Cow- ley (2010) note that on a plot of Probability vs Impact, iso-risk lines should be hyperbolic and thus the rectangular categorizations of a risk matrix are conceptually wrong, yielding over- and under-prior- itization of risks. They further state that “….there appears to be little scientific analysis of their value in improving risk related outcomes.” Thomas et al. (2014) note that “Risk Matrices produce arbitrary decisions and risk-management actions. These problems cannot be overcome because they are inherent in the structure of the Risk Matrices.” Wijnia (2012) argues that “The problems and criticisms [associated with risk matrices] concentrate on 3 points: (i) the risk matrix does not prioritize distinguishable risks, (ii) the risk matrix prioritizes risks incorrectly, and (iii) the risk matrix results in incor- rect decisions on mitigations.” Despite these known issues, heat-map risk matrices are still widely used and, in fact, are recommended by prestigious organizations such as the Project Management Institute, the International Council on Systems Engineering, and the U. S. Department of Defense, pos- sibly because the flaws are not well-understood or because the al- ternatives are perceived to be too complex. In this paper, we attempt to simplify some of the arcane technical explanations of the weak- nesses and present a simplified, practical, alternative approach to Project Risk Prioritization. FIGURE 01. Typical risk matrix. 2 Impact: Probability Low Medium High Very High Very High High Moderate Low Figure 1: Typical risk matrix. Heat map -ty pe risk matrices are implicitly based on the expected value theory of risk, in which expected loss (EL ) is the product of risk probability and risk impact: EL = P x I where EL = expected loss P = Probability of the risk occurring (between 0 and 1.0) I = Impact of the risk (often expressed in dollars) For example, if an individual believes that there is a 70% chance of losing $100,000, then the expected loss is $70,000 according to Expected Value Theory. Using this principal, t he risks are color-coded, typically using red to indicate risks having high probability and high impact ; orange or yellow to indicate risks with intermediate combinations of impact and probability ; and green to indicate risks having either low impact or low probability or both . Red risks take the highest priority, yellow and orange intermediate, and green the lowest priority. Once risks are prioritized, organizations typically apply most resources and urgency to their highest -priority risks ; lower priority risks are de- emphasized and may be eliminated entirely from further risk management. Improper risk prioritization can waste resources, cause projects to fail, and in extreme cases cost lives . Risk matrices suffer from serious flaws: 1. They are qualitative and subjective, and definit ions of “high”, “medium,” and “low” may mean different things to different people. 2. They are typically presented as symmetric about the diagonal, which is often invalid. 3. They do not account for risk aversion, which is manifested by almost every entity in making decisions. 4. The breadth of the categories may result in serious prioritization errors. Heat map-type risk matrices are implicitly based on the expected value theory of risk, in which expected loss (EL) is the product of risk probability and risk impact:

EL = P x I where EL = expected loss P = Probability of the risk occurring (between 0 and 1.0) I = Impact of the risk (often expressed in dollars) For example, if an individual believes that there is a 70% chance of losing $100,000, then the expected loss is $70,000 according to Expected Value Theory. Using this principal, the risks are color-coded, typically using red to indicate risks having high probability and high impact; or- ange or yellow to indicate risks with intermediate combinations of impact and probability; and green to indicate risks having either low impact or low probability or both. Red risks take the highest priority, yellow and orange intermediate, and green the lowest priority. Once risks are prioritized, organizations typically apply most resources and urgency to their highest-priority risks; lower priority risks are de-emphasized and may be eliminated entirely from further risk management. Improper risk prioritization can waste resources, cause projects to fail, and in extreme cases cost lives.

Risk matrices suffer from serious flaws: 106 JOURNAL OF MODERN PROJECT MANAGEMENT • MAY/AUGUST • 20182018 • JOURNALMODERNPM.COM 107 AN ALTERNATIVE TO HEAT MAP RISK MATRICES FOR PROJECT RISK PRIORITIZATION THE PROBLEMS --------------------- --- A. Subjectivity --- All risk assessment involves some subjectivity in assessing both the probabili- ty and impact of risks, but risk assessment matrices seem to magnify this issue.

Common verbal descriptors for probability include “Very High,” “High,”, “Medi- um,” “Low,” “Almost Certain,” “Highly Likely,” “Possible,” and “Unlikely.” Common descriptors for impact include “Low,” “Medium,” “High,” “Very High,” “Minimal,” “Major,” and Catastrophic;” there are many others. The descriptors are wholly subjective and different people might have very different quantitative figures in mind for a probability that corresponds to “High” or an impact described as “Me- dium”. The imprecision of the verbal descriptors can lead to prioritization errors.

Although subjectivity cannot be eliminated from risk management, the tools that are used should certainly not add to the inherent subjectivity.

--- B. The Error of Symmetry--- Most risk matrices are symmetric or near-symmetric about the diagonal (Univer- sity of Sydney, 2016; Department of Defense, 2006; INCOSE, 2015; Project Man- agement Institute, 2008.) That is, they treat a High Probability-Very High Impact (H-VH) risk with the same priority as a Very High Probability-High Impact (VH-H) risk. This is fundamentally wrong and can lead to huge errors in risk prioritiza- tion. Consider the risk matrix shown above in Figure 1, which is symmetric about the diagonal. A Very-High Probability-High Impact (VH-H) risk is designated red, as is a High Probability-Very High Impact (H-VH) risk; thus they are both treated with the same priority. But let’s assign quantitative values to the axis descriptors: are colored red if the product of Impact and Probability exceeds $500,000; or- ange if the product is between $100,001 and $500,000; yellow if the product is between $10,001 and $100,000; and green if the product is less than $10,000.

These thresholds are arbitrary and may be adjusted by the user; this is easily ac- complished using conditional cell formatting in MSExcel. The distribution of cell colors in Table 3 is very different than that in Figure 1 and therefore the risk pri- oritization is different.

In addition, Table 3 is not symmetric about the diagonal. For example, the Very High Probability-Medium Impact (VH-M) value of $90,000 is less than 20% of the Moderate Probability-Very High Impact (M-VH) value of $500,000; yet the conventional heat map risk matrix would have categorized these two risks with equal priority. The one with the larger dollar impact is much more concerning.

Similarly, the VH-H risk of $270,000 is only 36% of the H-VH risk of $750,000 and requires different prioritization, but the conventional risk matrix of Figure 1 classified them both as red.

Clearly, using undefined subjective verbal descriptors and symmetric tables does not yield good risk prioritization or subsequent decision making.

--- C. Risk Aversion --- Unfortunately, the problem gets worse. Under expected value theory (where EL = P x I) a risk with high P and low I can have the same expected loss as one with low P and high I. For example, if an individual believes that there is a 10% chance of losing $100,000, then the expected loss is $10,000 according to Expected Value Theory. Similarly, a 1% chance of losing $1,000,000 would also have an expected loss of $10,000. Therefore, these two risks would be treated equally and would garner the same prioritization color on a risk matrix. But most people (and com- panies) feel differently about those two risks: they are much more concerned with the second risk than the first because of risk aversion, and would assign the second risk a much higher priority. While probabilities are bounded by 0 and 1.00, potential financial impacts are unbounded: the maximum probability one could see is 1.00 but the maximum dollar impact could be in the millions, billions, or higher. People tend to focus on the potential dollar loss more than on the prob- ability. Risk aversion is exhibited by individuals, organizations, teams, and compa- nies, most of whom are highly risk averse when dealing with large potential dollar losses (Taylor & Weerapana, 2010; Binswanger, 1981).

One may account for risk aversion by inferring a utility function for the deci- sion-maker (Clemen and Reilly, 2014). The utility function quantitatively de- scribes the entity’s risk aversion and may be used to correct the Expected Loss (EL) calculated using expected value theory to a Risk-Adjusted Loss (RAL). The RAL may be calculated in several ways. One of the simplest methods is to use the Mean Variance Utility Function (MVUT) (Pratt, 1964; McNamee & Celona, 1987), which calculates the RAL as:

In equation 1 RT is the Risk Tolerance of the organization or individual for whom the project is being conducted 1 and σ 2 is the variance. The variance σ 2 is an indicator of the uncertainty associated with the risk and may be calculated from the equation 4 Most risk matrices are symmetric or near-symmetric about the diagonal (University of Sydney, 2016 ; Department of Defense, 2006 ; INCOSE, 2015; Project Management Institute, 2008 .) That is, they treat a High Probability -Very High Impact (H-VH) risk with the same priority as a Very High Probability -High Impact (VH -H) risk. This is fundamentally wrong and can lead to huge errors in risk prioritization. Consider the risk matrix shown above in Figure 1, which is symmetric about the diagonal. A Very -High Probability -High Impact (VH -H) risk i s designated red, as is a High Probability -Very High Impact (H -VH) risk; thus they are both treated with the same priority. But let’s assign quantitative values to the axis descriptors: Table 1. Quantified Probability Descriptors Table 2. Quantified I mpact Descriptors Probability Descriptor Probability Very High .9 High .75 Moderate .5 Low .25 [As noted above, the descriptors are subjective and may mean different things to different people; another individual might assign entirely different values to the descriptors in Tables 1 and 2, and this might change the resulting risk prioritization significantly. In addition, each verbal descriptor probab ly relates to a range of values; for simplicity, range mid -point values are used here. ] If one replaces the verbal descriptors in Figure 1 with the quantitative val ues of Tables 1 and 2, one obtains Table 3: Table 3.

Risk Aversion Unfortunately, the problem gets worse. Under expected value theory (where EL = P x I) a risk with high P and low I can have the same expected loss as one with low P and high I. F or example, if an individual believes that there is a 10% chance of losing $100,000, then the expected loss is $10,000 according to Expected Value Theory. Similarly, a 1% chance of losing $1,000,000 would also have a n expected loss of $ 10,000. Therefore, these two risks would be treated equally and would garner the same prioritization color on a risk matrix. But most people (and companies) feel differently about those two risks: they are much more concerned with the second risk than the f irst because of risk aversion, and would assign the second risk a much higher priority.

Risk aversion is exhibited by individuals, organizations, teams, and companies, most of whom are highly risk averse when dealing wi th large potential dollar losses (Taylor & Weerapana , 2010; Binswanger, 1981 ). One may account for risk aversion by inferring a utility function for the decision -maker (Clemen and Reilly, 2014). The utility function quantitatively describes the entity’s risk aversion and may be used to correct the Expected Loss (EL) calculated using expected value theory to a Risk -Adjusted Loss (RAL). The RAL may be calculated in several ways. One of the simples t methods is to use the Mean Variance Utility Function (MVUT) (Pratt, 1964 ; McNamee & Celona, 1987), which calculates the RAL as: RAL = PI + σ 2/[2 (RT)] (1) 6 In equation 1 RT is the Risk Tolerance of the organization or individu al for whom the project is being conducted 1and σ 2 is the variance. The variance σ 2 is an indicator of the uncertainty associated with the risk and may be calculated from the equation σ2 = (PI) 2(1 -P) + (PI- I) 2 x P (2) which simplifies to σ 2 = PI 2(1 -P). (3 ) Substituting this expression into equation 1 yields RAL = PI [1+ (1 -P)I/(2 RT)] (4) Risk Tolerance RT is the capability of an entity to absorb risk. It is a dollar amount, and the larger, the greater the ability to absorb risk. Corporations typically have much greater RTs than individuals. For relatively risk -averse companies, a rule -of thumb is RT= .064 x (annual sales) or 1.24 x (net income) or .157 x (equity) (Howard, 1988). Typically, individuals have RTs in the tens of thousands or hundreds of thousands whereas companies have RTs in the millions, tens of millions, or hundreds of millions. If one applie s equation 4 to the 2 risks described at the beginning of this section using a RT=$500,000 , the Risk -A djusted Loss is $10,9 00 for the first risk (P=.10 and I = $100 ,000) but RAL = $19,900 for the second risk (P=.01 and I = $ 1,000,000), as shown in Table 4 . (Recall that the Expected Loss for both risks was $10,000 and they were assigned equal priority according to expected value theory.) Table 4.

[As noted above, the descriptors are subjective and may mean different things to different people; another individual might assign entirely different values to the descriptors in Tables 1 and 2, and this might change the resulting risk prioritiza- tion significantly. In addition, each verbal descriptor probably relates to a range of values; for simplicity, range mid-point values are used here.] If one replaces the verbal descriptors in Figure 1 with the quantitative values of Tables 1 and 2, one obtains Table 3:

In Table 3, the cell values have been calculated by cross multiplying the Impact by the Probability, per Expected Value theory, which states that EL (Expected Loss) = Probability x Impact. The color-coding in Table 3 has been adjusted so that cells which simplifies to Substituting this expression into equation 1 yields Risk Tolerance RT is the capability of an entity to absorb risk. It is a dollar amount, and the larger, the greater the ability to absorb risk. Corporations typically have much greater RTs than individuals. For relatively risk-averse companies, a rule- of thumb is RT= .064 x (annual sales) or 1.24 x (net income) or .157 x (equity) (Howard, 1988). Typically, individuals have RTs in the tens of thousands or hun- dreds of thousands whereas companies have RTs in the millions, tens of millions, or hundreds of millions.

If one applies equation 4 to the 2 risks described at the beginning of this sec- tion using a RT=$500,000, the Risk-Adjusted Loss is $10,900 for the first risk (P=.10 and I = $100,000) but RAL = $19,900 for the second risk (P=.01 and I = $1,000,000), as shown in Table 4. (Recall that the Expected Loss for both risks was $10,000 and they were assigned equal priority according to expect- ed value theory.) ity) in Table 5 due to Risk Aversion, which increased its calculated value from $500,000 to $750,000. The risk-adjusted values are almost always greater than non risk-adjusted values due to risk aversion; they provide a much better indica- tion of how people and companies feel about risk.

--- D. Category Prioritization Reversal --- Unfortunately, the situation gets even worse. Consider 2 risks as shown in Table 6: 6 In equation 1 RT is the Risk Tolerance of the organization or individu al for whom the project is being conducted 1and σ 2 is the variance. The variance σ 2 is an indicator of the uncertainty associated with the risk and may be calculated from the equation σ 2 = (PI) 2(1 -P) + (PI- I) 2 x P (2) which simplifies to σ 2 = PI 2(1 -P). (3 ) Substituting this expression into equation 1 yields RAL = PI [1+ (1 -P)I/(2 RT)] (4) Risk Tolerance RT is the capability of an entity to absorb risk. It is a dollar amount, and the larger, the greater the ability to absorb risk. Corporations typically have much greater RTs than individuals.

In such a scheme Risk 1 would be Low Probability -High Impact while Risk 2 would be Low Probability -Very High Impact and Risk 2 would take a higher priority than Risk 1, which is clearly dramatically wrong.

In such a scheme Risk 1 would be Low Probability -High Impact while Risk 2 would be Low Probability -Very High Impact and Risk 2 would take a higher priority than Risk 1, which is clearly dramatically wrong. The error occurs be cause a probability of .005 is lumped into the same category as a probability of 0. 29 and because impacts of $499,000 and $501,000 (which differ by less than half a TABLE 06. Comparison of Two Risks Using either Expected Value Theory or risk-adjusted losses, Risk 1 has ~2 orders of magnitude greater expected loss than Risk 2 and should take a higher priori- ty.

In such a scheme Risk 1 would be Low Probabili- ty-High Impact while Risk 2 would be Low Probability-Very High Impact and Risk 2 would take a higher priority than Risk 1, which is clearly dramatically wrong.

The error occurs because a probability of .005 is lumped into the same category as a probability of 0.29 and because impacts of $499,000 and $501,000 (which differ by less than half a percent) are placed in different impact categories.

PRACTICAL EXAMPLE --------------------- The SideLobe Company ($12M annual sales) designs and de - velops surface and air search radars for various industrial sectors including commercial, state, and federal organizations.

SideLobe has decided to embark on a risky air search radar project for the Navy. The radar is risky because it takes advan - tage of newly developed software algorithms that automatically detect, track, identify, engage, and destroy air targets. Typical radars of this type normally require human intervention to assess threats and engage them with the appropriate weapon system.

The SideLobe Robotic Acquisition System (RAS) automates this entire process without human intervention.

At the outset of the project SideLobe consulted various references (including the Project Management Body of Knowledge (PMBOK)), and established the probability and impact verbal descriptors shown in Table 7 for use in the risk assessment.

SideLobe then developed a list of project risks, of which the 5 most significant are shown in Table 8.

Using the typical Heat Map Risk Matrix as prescribed by the PMI and INCOSE, SideLobe then depicted the risks as shown in Table 9 in which the numbers in the 5 cells corre - spond to the 5 risks: 9 The SideLobe Company ( $12M annual sales) designs and develops surface and air search radars for various industrial sectors including commerci al, state, and federal organizations.

To demonstrate the value to the project manager of the Risk - Adjusted Loss method of project risk prioritization, 2 field studies were conducted. In the first, 5 WPI Systems Enginee ring professors (all of whom were familiar with heat -map type risk matrices for risk prioritization) were ask ed to prioritize 5 given risks whose probabilities and $ impact s were provided (see Table 12 ) using a heat -map risk matrix.

BENEFITS FOR THE PROJECT MANAGER - FIELD VALIDATION --------------------- Determining a project risk’s probability and potential impact are steps 1 and 2 of the Project Risk Management approach de - scribed in the Introduction. This study, however, assumes that the impact and probability have been determined for each pro - ject risk, and focuses on the correct prioritization of the risks once they have been characterized. To demonstrate the value to the project manager of the Risk-Adjusted Loss method of pro - ject risk prioritization, 2 field studies were conducted. In the first, 5 WPI Systems Engineering professors (all of whom were familiar with heat-map type risk matrices for risk prioritiza - tion) were asked to prioritize 5 given risks whose probabilities and $ impacts were provided (see Table 12) using a heat-map risk matrix.

The 5 professors (identified as A, B, C, D, and E) came up with 4 different prioritizations, as shown in Table 13.

The prioritizations are significantly different for 4 of the 5 pro - fessors. The same 5 professors were then asked to prioritize the same 5 risks using the Risk Adjusted Loss method. This time, 4 of the 5 professors developed identical prioritizations: Risk 3 followed (in order) by risks 2, 1, 5, and 4; the 5th professor ob - tained a prioritization of Risk 3 followed by risks 2, 4, 1, and 5.

This shows that the heat-map style risk matrix cannot be relied the risk. It's a better visual representation of the data, and it better informs decision mak - ers with clear and concise evidence” and “The RAL method was easier because it didn’t really involve any creativity, critical thinking or brain power. We have the formulas and tables, so lit - erally all I did was plug it all into Excel and let it do the math. The Risk Matrix method involved thinking about the different categories and 110 JOURNAL OF MODERN PROJECT MANAGEMENT • MAY/AUGUST • 20182018 • JOURNALMODERNPM.COM 111 AN ALTERNATIVE TO HEAT MAP RISK MATRICES FOR PROJECT RISK PRIORITIZATION their bands, doing some internal reflection on what I thought they should be grouped as, and looking at the results once I prioritized the risks to make sure they made sense. Neither method was really hard to use, but the Risk Matrix method took longer and was more effort.” Typical comments from those who felt the Heat-Map method was easier included, “I believe the Heat-Map Matrix would be considered easier to use only in that there is no math involved and it might be less intimidating to some people. But that is not to say the RAL isn’t easy, in fact, it’s pretty straight forward and easy enough to use” and “Since I am, as well as many of the Sponsors I encounter each day, very familiar with the Heat Map Risk Matrix, that gives it a leg up on ease. Also, since many of these same Spon- sors are non-technical with even simple equations and numbers hurting their heads, I would say that the Heat Map Risk Matrix method will continue to be easier accepted, as they would “understand” simple probabilities and impacts much easier than Expected Loss, Risk Tolerance, and Risk Adjusted Loss. That said, the use of a Heat Map Risk Matrix always has and always will be more “qualitative” than “quantitative” in both how the probability ranges are determined and defined (why 0%-20%, why not 0% to 10%??), and most certainly how impact ranges are categorized (Minor, Moderate, Major) and assessed. Thus, I would say that the Heat Map Risk Matrix is “easier” to use.” The general consensus seemed to be that for those who are not intimidated by numbers and calculations, the RAL method is easier to develop, but less familiar than the heat map, which is well-known and therefore may be eas- ier to use as a risk communication tool.

A large majority (88%) felt that the RAL method provided a more accurate prioritization. Typical comments from those individuals included, “Hands down the RAL provides a better prioritization. In fact I would go so far to say that the heat map does not really prioritize the risks. If you do not take expected value into account, how can you compare. Specifically if someone is ranking the order I am not really sure by what basis you do this. In prac- tice, the only real use I have seen of the colors was a way to form a basis to ignore an issue that has no practical solution. Every other time the colors just track who is monitoring the steps to fix the risk” and “The heat map limits you to bucketing risks into 3 categories (well one can do more colors) and the bucketing does not do a good job of handling prioritization by com- bining impact and probability. The RAL uses a straightforward calculation to prioritize the risks which includes the effects of risk aversion. Heat map does not cover risk aversion.” Of the few respondents who felt that the Heat- Map approach provided more accurate prioritization, comments included, “A better visual aid in how to explain why a risk is more important to the project than other. It can be used for your own use, it can be easily recog- nized by others without formal training, and can be manipulated as needed to reflect an ever changing risk landscape” and “Heat-map matrices are a very good visual to show the impact of something that could be more than just monetary significance. If a risk has a lower monetary value but longer outage time than another risk, that impact could be included in a heat-map matrix, where that wouldn’t necessarily show up in an RAL.” The clear consensus was that the RAL approach is more quantitative while the heat map is qualitative; that the RAL technique reduces prioritization errors, and that the RAL technique is superior because it allows for risk aversion.

The bottom line in assessing the 2 techniques, however, is the consisten- cy with which different project managers prioritize the given risks. For the heat-map prioritization method, the consistency among managers was very poor. Sixteen different prioritizations were provided by the 25 project man- agers, only one of which (Risks 1, 3, and 5 as top priority and Risk 2 and 4 as lowest priority) was provided by more than 2 individuals. Seventeen individuals rated Risk 1 as the top priority while 5 rated it the lowest. Sev- enteen rated Risk 3 the top priority while 5 rated it the lowest. This great inconsistency demonstrates the weakness of the heat-map approach in pri- oritizing risks. With exactly the same data on risk probability and impact, there is great variation in the resulting priorities deriving from the heat- map approach.

The RAL method yielded substantially better (but not perfect) consistency in risk prioritization. 100% of the respondents listed either Risk 2 or 3 as the highest priority and Risk 4 or 5 as the lowest. Twenty project managers (80%) came up with a prioritization of either Risks 3, 2, 1, 5, and 4 (in order) or Risks 2, 1, 3, 5, 4. Of those 20 project managers, 9 (36%) prioritized the risks (in order) as Risks 3, 2, 1, 5, and 4 while 11 (44%) determined the pri- oritization to be Risk 2 followed by Risks 1, 3, 5, and 4. The reason for this bi- furcation in prioritization is interesting and surprising: those who obtained the “correct” prioritization (the prioritization that accrues when Equation 4 is applied correctly: Risks 2, 1, 3, 5, 4) interpreted Equation 4 as RAL=PI + PI 2(1-P)/[2(RT)]. Those who obtained the “incorrect” prioritization (3, 2, 1, 5, 4) misinterpreted Equation 4 as RAL=PI + (PI) 2(1-P)/[2(RT)] [note the parenthesis around the second PI term.] This surprising error underscores the need to be extremely clear in the expressions used for equations, even when following notation conventions, when administering the RAL tech- nique to prioritize risks.

The 5 project managers who developed neither of the 2 most common pri- oritizations typically made simple calculational or observational errors. For example, two rated Risk 4 as a higher priority than Risk 5 even thought they had calculated a higher RAL for Risk 5. One dropped a zero in the RAL cal- culation and 1 did not use the correct equation, dropping the (1-P) term in Equation 4. These errors underscore the need to check calculations careful- ly (perhaps by another analyst) when using the RAL method.

Despite the calculational and observational errors and those caused by misinterpretation of Equation 4, the prioritization consistency derived from the RAL method is substantially better than that deriving from the heat-map method. Addressing those errors via checking calculations with a 2nd analyst and clarifying the interpretation of Equation 4 should dra- matically improve the consistency of the RAL method. The better consist- ency afforded by the RAL method indicates that the RAL method is a better tool for risk prioritization than the heat-map and thus provides substan- tial value to project managers.

(You may use only 2 colors (e.g. red and green), 3 colors (red, yellow, green), 4 colors (red, orange, yellow, green) or any other scheme that you like. STEP 2. Establish Probability Categories and Bounds 1. For the probability (or “likelihood”) you will have as many probability categories as the number of rows you decided upon in Step 1. Now you need to name them e.g. “Low,” “Medium,” “High,” (if you have 3 categories) or “Very Low,” “Low,” “Medium,” “High,” “Very High” (if you have 5 categories). You may use any names you like (e.g. “inconsequential” instead of “very low”). 2. Now you need to establish the bounds for each probability category; that is, you must break the probability scale (0-100%) up quantitatively. You may use any scale you like: linear, logarithmic, some combination, or any other scale. Examples might be: STEP 3. Establish Impact Categories and Bounds 1. For the impact you will also have as many impact categories as the number of columns you decided upon in Step 1. Now you need to name them e.g. “Low,” “Medium,” “High,” (if you have 3 categories) or “Very Low,” “Low,” “Medium,” “High,” “Very High” (if you have 5 categories). You may use any names you like (e.g. “inconsequential” instead of “very low”). 2. Now you need to establish the bounds for each impact category; that is, you must break the impact dollar scale ($0 -$X) up quantitatively. You may use any scale you like: linear, logarithmic, some combination, or any other scale. Examples might be: Pro bability Range (%) Category 0-20% Very Low 21-40% Low 41-60% Medium 61-80% High 81-100% Very High Pro bability Range (%) Category 0-20% Low 21-80% Medium 81-100% High or 22 STEP 4. Categorize each Risk by Probability P and Impact I 1. For each of the 5 risks that you have been given, you must categorize both their probability and impact using the scales that you developed in steps 2 and 3 above. For example, if a given risk (“Risk a”) has a probability of 15% and an impact of $3,000,000, and if your category bounds are as follows: Then you would categorize this risk as “Very Low Probability, High Impact.” Similarly, a risk with a probability of 50% and an impact of $280,000 (“Risk b”) would be categorized as “Medium probability, Low Impact.” Categorize all 5 given risks in this manner. STEP 5. Locate Each Risk on the Matrix: The 2 risks described above (Risk a: Very Low Probability, High Impact; and Risk b: Medium Probability, Low Impact) would be placed as shown below on this particular risk matrix: Clearly, Risk a’s priority is green and Risk b’s is Yellow.

They suffer from subjectivity, lack of consideration of psychological factors important in decision-making, and categorization errors, all of which can yield significant risk mis-prioritization. The result can be wasted resources, failed projects, and in extreme cases loss of life. This paper describes a risk prioritization approach based on Risk-Adjusted Loss that obviates these weaknesses. All of the techniques demonstrated herein are easily implemented in spread- sheet programs such as MS Excel using standard equation operators, utility functions, and conditional formatting. These techniques will yield better risk prioritization and hence fewer wasted resources, more successful pro- ject outcomes, and in extreme cases may even save lives. 112 JOURNAL OF MODERN PROJECT MANAGEMENT • MAY/AUGUST • 20182018 • JOURNALMODERNPM.COM 113 AN ALTERNATIVE TO HEAT MAP RISK MATRICES FOR PROJECT RISK PRIORITIZATION • APPENDIX • Clearly, Risk a’s priority is green and Risk b’s is Yellow.
