Organisations can begin to identify the processes that may require re-engineering by using a flowchart. Flowcharts are graphical representations of the workflows that businesses use to analyse and document existing systems, as well as design and manage process re-engineering efforts. A flowchart uses symbols to represent workflows and decisions.
Table 1 Flowchart key
|Data||This symbol represents data. It is not intended to be specific as to the type of medium for the data|
|Stored data||This symbol represents stored data, which is intended as data that is ready for processing. It is not intended to be specific as to the type medium for the stored data|
|Process||This symbol represents a processing function. For example, it may indicate a single, defined operation that changes the value of information. Alternatively, it may indicate a group of operations that change the value or form of information. It may also represent the determination of one of several directions to be followed in a flow|
|Line||This symbol represents the flow of data or control. It may include solid or open arrowheads to indicate direction of flow where necessary or to enhance the readability.|
The basic symbols for a flowchart, as described by the International Organisation for Standardisation (ISO) are shown in Table 1. The ISO also describes a number of specific symbols for data and process that are not referenced in the figure.
