agement is a key to managing  time-  based information flows. We then review how process 

modelling is used to analyse information flows to optimise business processes and then look 

at information storage analysis through a brief review of data modelling.  

  Process  modelling 

 Traditional approaches to process analysis use established systems analysis and design 

methods that are part of methodologies such as Structured Systems Analysis and Design 

Methodology (SSADM), like the data flow diagram technique outlined in Bocij  et al  .  (2008). 

Such approaches often use a hierarchical method of establishing 

   

●

● 

  the inputs (resources) needed by the processes and the outputs.
