Sensitivity ∆ (delta) Alternatives page shows the changes in overall alternative priorities when alternative performance with respect to one or more covering objectives is changed. If you change an alternative's priority with respect to a single objective, you'll see the effect on the alternative's overall priority.
When the priority of an alternative is changed with respect to (wrt) an objective, we do not adjust the other alternative priorities (normalize to 1) as we do when we change the objective priorities in Sensitivity Δ delta Objectives.
Let's look at the information that is contained in this graph piece by piece.
First, the relative importance of the covering objectives are depicted by the vertical blue bars and shown numerically at the side of each bar or by hovering on the bars:
Second, the relative performance with respect to the covering objectives is shown by small circles representing each of the alternatives.
Hovering on a circle displays a tooltip with the designated alternative name, its priority with respect to the covering objective, and Delta (0% indicates that the priority is based on actual participant judgments).
Below shows that Plumtree Corporate Portal is the best performing alternative (100%) with respect to Vendor/Partner Access.
The lines connecting the alternatives from one objective serve to help you find a particular alternative as you move from one objective to another.
Finally, the intersection of the alternative line segment with the overall axis (gray vertical bar) shows the relative overall priority of the alternatives, which are also displayed at the right with the alternative names.
To temporarily change the performance of an alternative given a covering objective, and see how it will affect the overall performance of the alternatives, simply drag the alternative circles up (increase performance) or down (decrease performance). The %delta will increase or decrease as you drag the plot up or down.
From above, we see that the original priority of Customer Service Call Center with respect to Vendor/Partner Access is 18.39% and it's the fifth most preferable alternative in the overall priorities. As we increase its priority by dragging the violet circle upward, we see that Customer Service Call Center becomes the third most preferable alternative in the overall alternative priorities.
You can select/deselect objectives so you can view only the alternative performance for fewer covering objectives or for a given cluster. This is done by checking/unchecking the checkboxes to the right of the objective nodes.
