What a digital twin of an organisation is
A digital twin of an organisation is a model that mirrors the real one: every application, process, capability and piece of technology you run, and the relationships between them — this system depends on that platform, this capability is realised by that application, this risk threatens that process. Most organisations hold the pieces of this picture in separate places: a spreadsheet of applications, a diagram from a past project, a risk register nobody has reopened since the audit that produced it. None of those on its own can answer a question that crosses more than one of them, such as what actually happens if one system goes down, because the dependency was never written down anywhere a computer can read.
Entelim's twin is built from two kinds of connection. An explicit relationship is one you recorded or imported directly, in ArchiMate — the open modelling notation behind the model, with element types such as application component, business process or node, and relationship types such as serves, realises or depends on, across the business, application and technology layers. A derived relationship is a further connection Entelim works out, rather than one anyone recorded by hand, from a chain of explicit relationships, by a named rule, rechecked whenever the model changes. On screen, Entelim calls this "what we worked out".
