We have 4 node types which we use to describe an Information Supply Chain (ISC);
Information: these nodes represent any type of information used in the ISC. It could be a paper form or it could be a table in a database. It doesn't matter. You can be as generic or as detailed as you need to be. The Supertype is a generic Information Node and we have provided some different Types for you. In future versions, you will be able to create your own Information Nodes, add them to the Information Palette and re-use them from the palette across all of your diagrams.
Action: These nodes record the actions that are performed on Information Nodes to create new or derived information. Actions are performed by people or a system. Actions have a duration and a frequency; how long they take to perform and how often then happen. This information is used in the calculation of ISC cost. Types include organisations, capture, process and outcome. As per information nodes, in a future release you will be able to create your own action nodes.
System: these nodes describe the systems used through the ISC, typically supporting the storage of Information or used by people to perform an action. Types include on-premise or cloud based systems. As for all nodes, in a future version you will be able to create your own system nodes.
People: these nodes represent the people involved in the ISC. People use systems to perform actions. Types include a team, a named individual or an unnamed individual. As for all nodes, in a future version you will be able to create your own people nodes.
