The WA and BMF illustrate how the selected vendors measure up to the user's requirements. Because data has been collected and analyzed in a knowledge tree, users can pinpoint the results on different functional categories, and see how the vendors performed in a certain area. Costing can also be factored into the comparison and what-if scenarios can be created. What-if scenarios allow users to interactively modify results to immediately see the impact on vendor performance. The original results are immediately recalculated.

Standard and customizable graphs of product comparisons and reports are also available to provide a detailed overview of the selected system's strengths and weaknesses. Graphics include

• Product comparison graphs. Provide a detailed overview of the selected systems' respective strengths and weaknesses and pinpoint key differentiators among the solutions. Users can drill down to investigate where the gaps between solutions are more prominent and what the gaps' sources are.
• Product differences graphs. Illustrate gaps in performance between the selected baseline product and other products for every criterion on the currently selected level in the knowledge tree.
• Sensitivity graphs. Allow users to compare solutions based on a long-term business vision to verify if the software package will still be an ideal solution based on future needs.

Ultimately, these scores allow the user to compare vendor solutions, side by side, accurately.
