Then identify the member you would next most like to improve,
and assign it a swing weight that reflects your estimate of the
relative importance of improving this member compared with
improving the first member. For example, if you feel that
improving the second member is 75 percent as important as
improving the first member, give the second member a swing
weight of 75.
You can continue to assign swing weights by comparing the
importance of improving each of the remaining members to the
first member's importance.
You can also enter swing weights by changing the lengths of the
bars. To change a bar's length, drag its right hand edge.
When you have finished assigning the swing weights, click the
"Done" button. LDW will adjust the swing weights so they sum to
one and will let you review the adjusted weights. If you click
"OK," LDW will save the weights. If you click "Cancel" LDW
won't save the weights. In either case you will return to the assess
weights dialog box. If you click "Redo", LDW will return to the
smart method assessment screen.
Assessing Weights with Weight Ratios
The weight ratios method for assessing weights is similar to the
tradeoffs method. However, instead of defining tradeoffs
between pairs of members, you directly define the ratio of the
weights for the members in the pair.
To begin the weight ratios assessment process, select the
"pairwise weight ratios" assessment method and click the "Assess"
button in the assess weights dialog box. When you do this will
see the tradeoffs dialog box shown in Figure 7-11.
This dialog box lets you define and assess the weight ratios that
will define the weights for the active goal's members.
You pick a weight ratio to assess by selecting two members to
compare. First you select one member from the list labeled "First
Member:". Then LDW updates the list of allowable second
members based on the first member you select. Only pairs that
are "non-redundant" are allowed. Non-redundant weight ratios
can't be computed based on the other weight ratios.
