what is the 9 step decision making model that was proposed by Uustal

The 9 step decision making model is proposed by David Welsh in his book 'Decisions, Decisions'.
He calls it a subjective expected utility maximisation process. A utility, he explains, is a technical term
used by economists and philosophers to indicate happiness, pleasure or satisfaction.
The 9 step decision making model
Step 1 - Identify your objective
What is it you wish to achieve?
Step 2 - Do a preliminary survey of your options
Besides the most obvious choices available to you, what other kinds of options can you think of?
Step 3 - Identify the implicated values
What values are at stake here? If it's an easy or unimportant decision you may not necessarily do this
step. But if the decision has a major impact on your wealth, your health or self-respect, then it's useful
to be aware of it....
