A Very Important Decision Analysis Quote

Written by Will McGill on February 10th, 2010

As cited in Jurges (1973):

Ultimately all decisions are made on the basis of judgment.  There is no other way; and there never will be.  The question is whether these judgments are made in the fog of inadequate data, unclear and undefined issues or whether they can be made on the basis of adequate, reliable information, reliable experience and clear issues.  In the end, analysis is but an aid to judgment – judgment is supreme. – Katz and Kahn (1966)

The Many Questions of Risk: Toward a Triplet of Triplets

Written by Will McGill on January 6th, 2010

Note: Article updated on 17 Jan 2010

In 1981, Kaplan and Garrick published a paper entitled “On the Quantitative Definition of Risk” that defined risk as the set of all ordered triplets comprised of answers to the following triplet of questions (Kaplan and Garrick 1981):

  • What can go wrong?
  • How likely is it to go wrong?
  • What are the consequences?

These three questions set the stage for what most risk professionals consider to be the fundamental questions of risk assessment. In recent years, more questions have been suggested, including:

  • How much uncertainty is present in the analysis? (Lowder 2008)
  • Over what time frame? (Haimes 2009)
  • Are these risks tolerable?

In 1991, Professor Yacov Haimes offered a second set of three questions focused on the practice of risk management (Haimes 1991):

  • What can be done?
  • What options are available and what are the benefits and costs of each?
  • What impact do these options have on future options?

Mr. Bob Ross offered a few more interesting risk questions, including several for establishing the risk context (Ross 2009):

  • What are my risk management responsibilities?
  • What outcomes and objectives am I expected to achieve?
  • How are risks perceived by those to whom I am answerable?

Ross also offered a few more for risk management (labeled risk response or more generally risk treatment):

  • What could I do about it? (the “options” part of the second Haimes risk management question)
  • What should I do about it?
  • What will I do about it?

And a few more on risk management effectiveness:

  • How well is my chosen course of action working?
  • Has anything changed that requires altering my existing risk management measures?
  • Are there current trends and/or potential future developments that could require altering my existing risk management measures?

At a high level, Dr. Tony Cox summarizes all of risk analysis in terms of four high-level questions as follows (Cox 2009):

  • How bad is it? (Risk Assessment)
  • What to say about it? (Risk Communication)
  • What to do about it? (Risk Management)
  • Who to blame for it? (Risk Attribution)

Seeing how the ultimate goal of studying risk in general is to communicate risk knowledge to people that can then use it to make better (i.e., risk informed or risk supported) decisions. Risk communication, then, must consider the following lower-level questions that would help analysts decide on what to say about risk (Morgan et al. 2002; Apgar 2006):

  • What does the intended recipient think or know?
  • What does the recipient need to know?
  • How should it be told?

Mr. Bob Ross offered the following additional questions for risk communication:

  • Between whom does it need to be communicated?
  • How can the necessary risk information be most effectively communicated?

Of course, there is always the risk that a communication goes south, thus we should also entertain the questions:

  • How likely is it that the communication will work?
  • How bad would it be if it doesn’t?

If you look carefully at these questions, you might find some overlap among them and also find that they may be interpreted in different ways by different people. In fact, we could consolidate all of these questions into a triplet of risk analysis triplets. These are summarized as follows.  Given a clearly and precisely specified situational context (e.g., security context), risk analysis centers on the following nine broad questions:

Risk Assessment Triplet

  1. What can happen? Answer: scenarios characterized by the pairing of cause and outcome, where associated with outcome is the time frame
  2. How likely is it? Answer: product of probability of cause and probability of outcome given cause; uncertainy in the answers is captured using imprecise probabilities
  3. How bad would it be? Answer: severity of the cause/outcome pair

Risk Communication Triplet

  1. What does the recipient presently think, know and perceive? Answer: the recipient’s mental model and lens for interpreting and integrating new information
  2. What does the recipient need to know? Answer: key messages to improve the recipient’s understanding
  3. How should it be told? Answer: in what form must the information be communicated and who should communicate it, this includes all risks associated with communications

Risk Negotiation Triplet*

  1. What can be done? Answer: the types of changes that can be made in the time frame of interest
  2. What options are available? Answer: Answer: real feasible options that are available with assessed benefits and costs of each, where benefits and costs include impact on future options, and all assessments include uncertainty
  3. What should be done? Answer: compares benefits, costs and risks of each option in addition to other factors with a variety of non risk-related alternatives including the “do-nothing” option
*Note: In this context, Risk Negotiation refers to an organization’s discussions and deliberations around a variety of risk treatments relative to the organization’s attitude and tolerance for risk.

Risk management revisits this triplet of triplets over and over again in perpetuity. With time, we learn how well our choices fared through continuous analysis and reanalysis of our systems and their environments. With every action we take, the systems we protect respond with new or modified risks with updated probabilities and severities, and new options and considerations emerge while others become infeasible or irrelevant. And of course, with time and change comes new uncertainties and misunderstandings, both of which require the dedicated attention of risk professionals to study and resolve.

Some Risk Quotes (Vol. 1)

Written by Will McGill on December 23rd, 2009

I typically come across a few excellent quotes that really resonate with what I am presently thinking about whenever I go on a paper reading binge.  Here are some interesting ones that I found recently:

Every year (or, perhaps, every day), some new industry or institution discovers that it, too, has a risk problem.  It can, if it wishes, repeat the learning process that its predecessors have undergone.  Or, it can attempt to short-circuit that process, and start with its product, namely the best available approaches to risk communication. – Baruch Fischhoff (1995)

Contemporary approaches to disaster reduction need to become more concerned with human-to-human relations, such as conflict resolution and consensus building among people, rather than human-to-nature relations. – Katsuya Yamori (2008)

See what I mean? (Nasrudin on Risk No. 1)

Written by Will McGill on December 22nd, 2009

(This is the first post containing a Nasrudin tale related to risk…)

Nasrudin was throwing handfulls of crumbs around his house.

‘What are you doing?’ someone asked him.

‘Keeping the tigers away.’

‘But there are no tigers in these parts.’

‘That’s right.  Effective, isn’t it?’ (Shah 4)

From a risk management point of view, Nasrudin asserts that because of his actions (i.e., throwing handfulls of crumbs around his house), all risks associated with the presence of tigers has been mitigated.  That is, Nasrudin believes that his actions reduced the probability of tiger presence to zero, thus bringing risk to zero.  And because no tigers have appeared, Nasrudin suggests that his strategy is “effective.”

Anyone have a good modern analogy to this sillyness?
