PrOaCT Decision Making model
The PrOaCT decision making model provides a systematic approach for making decisions.
it consists of eight elements that will help you make better decisions when worked through systematically.
The PrOaCT decision making model was developed by John S. Hammond, Ralph L. Keeney, and Howard Raiffa. They
described how to make a decision using the PrOaCT model in the book Smart Choices: A Practical Guide to Making Better Decisions.

The term PrOaCT is an acronym of the five core elements of the decision model…
The remaining three elements help clarify decisions in volatile or evolving environments…
Let’s take a look at each of the elements of this decision making model.
The first step to making a good decision is to work on the right decision problem.
The way you frame your decision problem drives everything else in the decision making process. it determines the
alternatives you consider as well as the way you evaluate them.
“a good solution to a well-posed decision problem is almost always a smarter choice than an excellent solution to a poorly posed one.”
Once you’ve framed your decision problem, it’s time to specify your objectives.
Why is this important? Because your objectives will form the basis for evaluating your alternatives. in other
words, they become the decision criteria.
in addition to making sure your decision gets you where you want to go, objectives also guide the decision
in order to make a decision you need to have alternatives to decide upon. it’s important to spend some time
to create imaginative alternatives. You want to have a wide range to choose from, so don’t
limit yourself here, get creative. Remember…
“You can never choose an alternative you haven’t considered.”
However, you also want to make sure the alternatives you’ve generated are good. Regardless of how many
alternatives you have, your decision can only be as good as your best alternative.
Here are some tips from Smart Choices for coming up with a good set of alternatives…
Once you’ve generated the alternative open to you, you need to understand the consequences
each alternative would have for each of your objectives.
Using a consequences table is a simple and powerful way to compare the alternatives.
When creating your consequence descriptions, it’s important to make sure they are accurate,
complete, and precise. Otherwise, you risk making a poor choice.
Many times, objectives will conflict with each other. as a result, you will have to evaluate tradeoffs
between the objectives. You will need to sacrifice something from one objective to gain something from another objective.
You can begin to consider tradeoffs by ranking the alternatives for each objective. This can be done using a
ranking table. a ranking table is structured the same way as a consequence table, but instead of noting consequence
descriptions, you put each alternatives rank relative to each other for that objective.
a ranking table will often enable you to eliminate some of the alternatives outright. in fact, it sometimes
even leads directly to the final decision.
Since most business decisions don’t happen in a static environment, it’s important that you clarify your
uncertainties. To make a good decision you need to judge the likelihood of different outcomes and assess
their possible impact.
a risk profile will help you capture the key information about how an uncertainty affects a
specific alternative. a risk profile will answer these four key questions…
Often, creating the risk profiles will make the smart choice obvious. But some complex decisions may need
further analysis to clarify the uncertainties. in these cases, a decision tree can help you make
a decision under uncertain conditions.
When decisions involve uncertainty, there’s always a chance that the desired consequence of your decision
will differ from the actual consequence. as a result, it’s important that you determine your risk tolerance.
Risk tolerance is the extent to which you are willing to risk experiencing a less favorable consequence
in your pursuit of a better consequence.
There are three steps you can take to incorporate risk tolerance into your decision…
Understanding your willingness to accept risk will help you choose an alternative with the right level of
risk for you.
The decisions you make today will influence the decisions you make in the future. These are called linked
decisions. To make your best decision about what to do today, you need to consider linked decisions.
There are six basic steps for analyzing linked decisions…
Understanding how decisions are linked combined with a little foresight will help you make better choices.
The PrOaCT decision making model is an excellent framework for guiding your important decisions.
