Information Nodes Describe:
• Information entities that contribute to the flow of information across
Information Supply Chain
• A range of Information Types such as paper, files, database layers,
services and applications
Ask yourself:
• “Does this represent a step along the Information Supply Chain?”
• “Is this really the source Information?
What creates that Information or Where does it come from?”
• “Is this really the end piece of Information? What business outcomes is it supporting or
who is the customer?”
Don’t be distracted by:
• The transactional information entities (if you’re interested in that
level of detail, Enterprise Architect is a better tool)
• Individual data entities such as fields in a table or pages in a report
• The ‘container’ for information such as a filing cabinet, a DBMS or a
supporting application; these are all
better described as the System that is providing the Information
• QA loops – these don’t contribute to the flow of Information
