This circle-spoke diagram example was crated on the base of the illustration in the article "What is an exposition?" from the Civil Aviation Safety Authority (CASA) website.
"As the aviation industry transitions to new rules and safety standards through regulatory reform, organisations will be required to demonstrate to the Civil Aviation Safety Authority (CASA) how they have met the requirements outlined in the legislation, including the regulations and manual of standards applicable to their operation through a document called an exposition.
An exposition is a description of how organisations will conduct their operations to maintain the required level of safety. The exposition is the primary document, supported by a series of manuals, such as the operations manual and safety management system manual. These manuals and other supporting documents form part of the exposition document set, as shown in the ... diagram." [casa.gov.au/scripts/nc.dll?WCMS:STANDARD::pc=PC_101706]
The hub-and-spoke diagram example "CASA exposition" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circle-Spoke Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.
