Next we will enter the measures for the performance goal:<br />

1. Select the "Performance" goal's box by clicking it. This<br />

will ensure that the new measures will be added below it.<br />

2. Click the Add a Measure button<br />

3. LDW will add a new measure under the "Performance"<br />

goal and display its dialog box.<br />

4. Change the name of the new measure to “Power.”<br />

5. Click the “Scale” tab.<br />

6. Change the units to “horsepower.”<br />

The range of horsepower for the three alternatives is from 109 hp<br />

to 175 hp. Describe this range to LDW as follows:<br />

1. Enter 175 into the “Most Preferred Level” edit box.<br />

2. Enter 109 into the “Least Preferred Level” edit box.<br />

Notice that -- unlike the "Price" measure -- more horsepower is<br />

preferred to less. LDW will know this since the most preferred<br />

level for "Power" is more than the least preferred level.<br />

Finally, we will define the "Fuel Economy" measure:<br />

1. If the "Power" measure is still highlighted, click the<br />

Add a Measure button again<br />

2. LDW will insert a new measure next to the "Power"<br />

measure (under the "Performance" goal).<br />

3. Change the name of the new measure to “Fuel Economy.”<br />

4. Click on the Scale tab.<br />

5. Change the units to “miles per gallon.”<br />

6. Enter 23 into the “Most Preferred Level” edit box.<br />

7. Enter 16 into the “Least Preferred Level” edit box.<br />

When you are finished, click "OK" and LDW will update the goals<br />

hierarchy to its final form. It should look like the hierarchy in<br />
