Explain the features of different systems
analysis tools and techniques for modelling
business processes.
Flow chart
Flowcharts are the most common sort of diagram in the world. Many people can understand it
because it uses few conventional symbols. Because of its simplicity, it is a potent and effective
instrument. In fact, BPMN is a more complex version of the basic flowchart technique.
Furthermore, most drawing software supports the production of flowcharts, which is used by a
much larger audience.
The flowchart employs a stepwise approach of actions and does not allow for a breakdown of
the activities. The Flow Chart model was possibly the first process representation. Although
there is no precise date for its origin, it has been widely used for many years.




Data flow diagrams
DFDs depict the movement of data or information from one location to another. DFDs are
diagrams that demonstrate how processes interact with people and the outside environment,
as well as how they are linked together through data stores.
They're utilised to keep track of the processes that have been analysed as part of the design
documentation. A DFD can be thought of as a way to organise data in its unprocessed
condition. DFDs, which were created in the early 1960s by Yourdon, are the foundation of
structured analysis.
