EMMA (Evolution Memory Management Assistant)
EMMA is an innovative tool which lets managers and developers collaboratively explore, select, and document alternative solutions to the problem of evolving a complex software system.In order to make well-informed decisions about the evolution of a software system through its sequence of releases, managers need access to information about interdependencies among the designs and development plans for different parts of the system. EMMA provides a convenient web-based interface for recording, managing, and disseminating this information.

Design evolution information in EMMA is organized around four interrelated concepts:
- System development goals and functional requirements;
- Solutions, which are approaches to meeting those goals and requirements;
- Assumptions and design constraints under which the goals are to be achieved;
- Change events, which may alter goals, solutions, assumptions, or constraints.
EMMA uses a Java/HTML-based hypertext interface, for easy deployment in any environment that supports standard web browsers. It also uses CoGenTex's advanced text generation technology to automatically generate various hypertext reports. Information entered in EMMA can include links to external documents, such as requirements or specifications created using other tools.
EMMA is being developed under the sponsorship of DARPA and AFRL as part of the EDCS (Evolutionary Design of Complex Software).
