Compendium is an implementation of IBIS. It is a collective intelligence platform. An early one. Another is ISM which had some early implementations following a different structured experience for the intelligence collection, rationalization, and decision making in terms of human strategies and actions. And Delphi, and others.
Compendium would have been nice to have been developed in Java, and then maintained as an open source infrastructure around these forms of activities. But that isn't where funding was able to take it, and that wasn't it's purpose. It was a social pioneering platform for the development of collective intelligence.
But there have been many such tools developed. Some more technically oriented to support activities like Six Sigma process management (think of QFD tools and various Six Sigma calculators, plus the structuring methodologies around group activities of measuring, analyzing, and innovating. Where the social AI tools have gone is further toward helping people make sense of each other as they dialog and collaborate. Cohere takes concepts started in IBIS and develops them further to help people think together, collectively, in an organized and focused fashion.
A reasonably straightforward effort could be made to move Compendium to the cloud using a JCloud set of standard migration plans. There are cloud vendors who should be able to do that at a reasonably low cost. JCloud would run on Google, Amazon, Azure, IBM, and any other serious vendor that offers an enterprise cloud platform - currently, that means built on Java. That could be done as triage for the current lack of tool support.
A more interesting option is to create an open source consolidated tool that brings together more than one technical tool (IBIS, ISM, Delphi, etc.) that forms the basis for facilitating collaborative intelligence gathering as an ongoing process, rather than as a project experience.
By the way - the key to Compendium is not the design of the Java Compendium code, it is the design of the IBIS group interaction process, and how a simple computer program, well thought out, can help humans exponentially multiple their effectiveness.
Is there an organizer in this group?
