The purpose of Ampersand is to help business architects deliver. Ampersand lets you demonstrate how your design complies to the rules by which the users of the system conduct their business, giving you information systems that do what users want.
Research into Ampersand focuses on automatically generating information systems, investigating a language suitable for designing such systems, and communication of designs between stakeholders with vastly different backgrounds.
Ampersand is a collaborative research project. You can learn more about Ampersand on its gitbook pages: https://ampersandtarski.gitbooks.io/documentation/content/
