Kiss Approach To Risk Based Decision Making

DESCRIPTION

Who doesn't have to make decisions? Private decisions? Job related/business decisions? No matter your age, position, job, we all have to make decisions almost on a day to day basis. Decisions alternatives, even the straight forward ones, often have hidden/secondary effects, and most of the time are made more difficult by our perception, sentimental values etc. Large corporations sometimes use highly sophisticated procedures to support their decisions on capital expenditure, investments, processes, and yet, oftentimes, they realize afterwards that the best option was not selected. Not to dig the dagger in the wound or work on the obvious, but if the world went into the global economic recession and crisis we have endured, it was precisely because decision making was based on improper parameters. The reason for these problems afflicting decision making is that risks (positive= winning aspects, negative=failure aspects) are not properly accounted for each alternative, and alternatives are not properly compared among each other. What you will find in here is a KISS (Keep it Simple) approach to decision making, applicable to any type of decision. In order to make it really simple, we had to simplify some areas to the bone (hence the remarks about a mathematician most likely fainting when reading our explanations). More sophisticated and rigorous methods do exist, especially if you want to compare in detail long term alternatives and produce/evaluate their financial results. We have books, blogs, courses and web site talking about them, but the purpose here was to really bring a somewhat impervious subject to the point it make sense for everyone to use it on a day to day basis, with a minimum of remote supervision/coaching. Welcome to the world of transparent, justifiable, decision making!

Of course it's very important for me to select the best alternative. 

In the past I have trusted my intuition, asked people....

They said I could do it,  without being an expert/mathematician, with their facilitation/supervision.

They said I should use a Quantitative Approach (i.e. based on numbers, money) to obtain concrete support to my selection.

They said not to worry and start immediately, coached remotely by them via email or Skype, or to follow one of their Seminars, read their Book, BLOG ....

It is quite simple to get started.. Just realize: for each Alternative, each thing that can go wrong or turn out positive has a certain likelihood of doing so, and if that happens I can make or lose some money. 

Let's look at some examples of Likelihood:

A coin has approximately ½ chances of coming out on une side: Likelihood 1/2=0.5A dice has approximately 1/6 chances of coming out with one specific number: Likelihood 1/6= 0.1667The weather forecast tells you the probability of precipitation (POP) tomorrow is 0.9, Likelihood =0.9= 9/10.

Here is the story of how it is done...some details are missing to keep the story short.

For any event a likelyhood can be evaluated, or estimated. 

It is always safe to make an optimistc and a pessimistic evaluation and say that the likelihood will be between so much and that much.

NB: Likelyhood, by definition cannot be smaller than zero, or larger than one.Likelihood One means the event is certain to occur, Likelihood zero (nil) means it will never occur. You should never use zero or one, as there will always be some uncertainty.  

I was told that I can learn estimation techniques for complex events, allowing me to formulate hi­low estimates. I learned that some guys out there are afraid of doing real estimates, so they use index nubers that end­up meaning nothing....and actually will guide them into critical mistakes. Others only use words, at at the end of the day they have a bunch of words, nothing more, available to them to support their decisions.

These guys constitute a Hazard...with a likelihood of dropping on Rozy a given volume. The Consequence is: a ruined day, the swimming suit to be washed etc.

Examples of tolerability curves.The next step? Any event can bring in positive or negativeconsequences (very rarely it can be neutral, meaning its consequence is basically nil)

To make it simple.. let's consider consequences as money (but could be anything else).

If your are betting in a game of dice or coins, then the consequence will be what you may win or lose from your bet.If you are considering the Alternative of opening a  cafè business downtown vs. bad weather, then you may be looking at an additional profit (because people will spend all day  at your cozy café), or a loss, if no one shows up.

For any event a consequence can be evaluated, or estimated. It is always safe to make an optimistc and a pessimistic evaluation and say that the consequence will be between so much and that much. Again, techniques exist to solve complex consequence evaluations with non­monetary stuff.

Those two guys told me they call that red line the “Pinocchio Nose” of the scenario.

If you are caught lying after an accident (hence the Pinocchio reference), your reputation will be more damaged:the more you lie, the longer the nose...easy!

By the way, small accidents (risks) can have a huge Pinocchio nose...if you are unprepared to deal with the crisis that may come  in the aftermath of the accident; when journalist willask you difficult questions in a moment of stress.

Thus: evaluate your risks and prepare for crises!

The two guys CONGRATULATED me!!! You have just compeleted your first Quantitative Risk Assessment (QRA), for one of the alternatives you have to chose from! 

They also said:

You are on a good way to make sensible and transparent decisions.

Please complete the same procedure for each alternative, and look at the three risk assessment plots (QRAs) once you are done.

So, I went home and set up for a long night of work...

Instead of telling me right away, they started asking me questions:

Mat, are there risks that you can afford (tolerate)?

Mat, which one of the Alternatives is the riskier?

Mat, which alternative would you select, now?

I realized I was not able to reply any of these questions and so, before I committed ritual suicide out of shear despair they said I needed to do one more thing: 

determine my tolerability to risks!

I had never heard talking about Risk Tolerability before.Basically, they said, tolerabiity criteria are different for each person, organization, corporation:

With three questions it is possible to determine the parameters of the tolerabiity criteria of anyone.

The questions may be answered in five minutes by an individual, or take a couple days of a facilitated workshop for a corporation, with its FCO and Board present.

Once it's done, it's a great tool, as it is the key to serious, concrete Entreprise Risk Management and to Risk Based Decision Making/Alternative Selection

Mat, which one of the Alternatives is the riskier (including of course upside and downside risks)?

Mat, which alternative would you select, now?

By determining my Tolerability curve and plotting it on top of the Risk Bubbles of each Alternative I can now reply the threequestions the guys asked me.

I felt great! Now I was able to select the best alternative for me,including postives and negatives of each, my appetite for risk, economic solidity.

People like Geo Pardy will not scare me away from  business or life opportunities!

What can I accomplish now?By using a transparent and sound quantitative

approach I can:

Scientifically select the most significant risks, Draw attention to the objective highest exposures (filtering emotional perceptions), andPrioritize them to allow reasonable mitigation in a very focused way.

I can clearly enhance the ability to prioritize risks for a rational and sustainable development.

BUT, more importantly

Create the basis to avoid a slide into

a crisis, by proactively

controlling the situation.

NB: Long term comparison of Alternatives requires the use of more sohisticated tools, such as CDA (Comparative Decision Analysis in replacement to classic NPV
