1. Select "Performance" and "Price" as the members for the
first tradeoff
2. Click the "Assess" button to begin.
The next dialog box asks you to select a representative from the
Performance goal for use in the tradeoff question. The
representative can be any measure or goal under a goal in the goals
hierarchy or the goal itself.
3. Select "Power" as the representative for the Performance
goal.
A new tradeoff question should appear. This time alternative B is
a hypothetical truck with a Price of $15,000 and 109 hp.
Alternative A is a truck with 175 hp and a price of $23,000.
Here, you might feel that you prefer alternative B, which is $8,000
cheaper.
4. Click on the "B" button to tell LDW.
5. LDW updates the screen and asks you to improve
alternative A by reducing its price until it becomes
equally preferred to alternative B.
You should be able to make A equally preferred because if you
reduce A's price to $15,000 it will equal the price of alternative B,
and have 175 hp to B's 109 hp. Then you should definitely prefer
A.
You can use your mouse to move the square for A or you can type
a new price for A in the edit box at the bottom of the screen.
Suppose that, after looking at a few possible levels and comparing
the alternatives, you decide that you would prefer A equally to B if
its Price were $20,000.
