LEONARDI MMI Engine™ takes as an input the LEONARDI MMI Model™. This customizable, dynamic and adaptable engine allows generating GUIs during all phases of the project, including early design, allowing rapid and reusable prototyping and taking into account business specific contexts and user profiles.

LEONARDI MMI Engine™ connects the GUI through its connector components with multi-source data and displays the GUI through display components, using a customizable presentation layer. The resulting application is portable, independent from underlying technologies, deployable in multiple environments (as fat clients or RIAs) and offers eased maintenance.
