A flowchart can be very beneficial in auditing crucial company applications and programs this kind of as business useful resource organizing systems (ERP) and provider oriented architecture (SOA) systems. As IT auditors we are involved with getting a distinct knowing of the hazards and controls in the engineering below evaluation. Flowcharts facilitate an exact assessment of an IT atmosphere.

In accordance to Wikipedia, the standard definition of a flowchart is a sort of diagram that represents an algorithm or procedure that displays knowledge and its movement typically with arrows. The use of flowcharts is frequent in numerous fields for evaluation, design and style, documentation and process administration.

Flowcharts are most valuable to visually exhibit organization procedures and the supporting technological innovation. Auditors can concentrate on distinct facets of information flows and infrastructure in these diagrams relying on the assessment of hazards and controls.

Events that can be captured in a flowchart consist of knowledge inputs from a file or databases, determination details, reasonable processing and output to a file or report. Risks and controls in a organization procedure can be documented visually and analyzed.

Four standard designs are generally used to create flowcharts. A sq. is employed for a procedure (e.g. insert, replace, save). A square with a wavy foundation is utilised for a document. A diamond is utilized for a choice point (e.g. sure/no, real/false). A sideways cylinder is utilized for knowledge storage (e.g. databases). These conventional designs were originally established by IBM and other pioneers of data engineering.

Extra designs contain circles, ovals and rounded rectangles for the start off and conclude of a organization process. Arrows demonstrate ‘flow control’ amongst a source image and a concentrate on symbol. A parallelogram represents enter and output e.g. knowledge entry from a kind, show to consumer.
