The name, V•I•S•A (Visual Interactive Sensitivity Analysis) reflects the principle design objective - to facilitate modeling and analysis in a way that is both visual and interactive, leading to improved understanding, better communication, and consequently, better considered decisions.

V•I•S•A for DOS was launched in 1988 and has been used worldwide to support decision making. In 1994 V•I•S•A for WINDOWS was launched; this is a new implementation that has been built completely within Windows, incorporating and extending the interactive facilities of V•I•S•A for DOS to the Windows environment.

The many new features, including the possibility to incorporate video or graphics depicting options, enhance the power of V•I•S•A to help you decide what is best for your organization. Use it to check out your own decisions or to facilitate group decision making.

V•I•S•A's Features

Draw / change the criteria hierarchy on screen using the mouse
No limit on the size or complexity of the criteria hierarchy or the number of options/strategies
Interactive input of weights and scores using bar charts or thermometer scales or numerical input
View criteria weights / option scores / option profiles at multiple levels of the hierarchy at the same time (each in its own window)
Drag the mouse to make changes to weights or scores
Immediately see the effects of any changes on all current displays, at all levels of the hierarchy
Sensitivity graphs show the effect on options of changing the weight of a selected criterion
Efficiency plots display the performance of all options on two selected criteria (e.g. cost Vs quality)
Non-linear relationships between measured scores and values
The ability to create snapshots of the model enables you to rapidly explore, and return to, several different scenarios
A facility to save customized screen layouts makes it easy to return to earlier views of the model
Incorporate visual images of the options to act as an aide-memoire and help discussion

DEA V•I•S•A
Uses "Data Envelopment Analysis" technology to automatically adjust weights to shows selected options in the best light. This enables fast review of the alternatives so that obviously dominated options can be removed from investigation and focused discussion can be promoted about appropriate weights.
