The scenario
A hospital CIO wants a quick-reference diagram of the information systems pyramid, from operational transaction systems to executive analytics.
What is in this drawing
Read the decisions behind it.
01Use four tier headings to map pyramid levels
EMR transactions, clinical MIS, CDSS, executive dashboards.
02
Include representative system examples under each tier to show scope.
Reuse for any layered information systems architecture where a base of transaction processing supports progressively higher-level management and decision support.
