A flowchart can be really helpful in auditing vital business programs and techniques this sort of as business source arranging techniques (ERP) and provider oriented architecture (SOA) methods. As IT auditors we are involved with receiving a obvious comprehending of the hazards and controls in the technological innovation under assessment. Flowcharts facilitate an correct evaluation of an IT surroundings.

According to Wikipedia, the basic definition of a flowchart is a variety of diagram that represents an algorithm or approach that shows information and its movement normally with arrows. The use of flowcharts is widespread in many fields for examination, style, documentation and procedure management.

Flowcharts are most valuable to visually screen company processes and the supporting technological innovation. Auditors can target on distinct facets of info flows and infrastructure in these diagrams based on the assessment of dangers and controls.

Functions that can be captured in a flowchart incorporate knowledge inputs from a file or databases, determination factors, rational processing and output to a file or report. Dangers and controls in a enterprise process can be documented visually and analyzed.

Four fundamental styles are generally utilised to develop flowcharts. A sq. is used for a process (e.g. insert, exchange, save). A sq. with a wavy foundation is employed for a doc. A diamond is employed for a decision stage (e.g. of course/no, correct/fake). A sideways cylinder is utilized for data storage (e.g. database). These traditional designs have been at first recognized by IBM and other pioneers of information technology.

Additional styles contain circles, ovals and rounded rectangles for the begin and stop of a enterprise approach. Arrows display ‘flow control’ among a source image and a focus on symbol. A parallelogram represents enter and output e.g. information entry from a form, show to consumer.

In creating flowcharts, there are some basic guidelines to stick to. Start off and stop points ought to be plainly described. The degree of depth documented in the flowchart need to be appropriate to the topic subject protected. The creator of the flowchart must have a obvious understanding of the method and the meant audience must be ready to follow the flowchart very easily.

Our staff of IT auditors, uses Microsoft Visio thoroughly to create flowcharts and to analyze business procedures.

This kind of a illustration on a flowchart makes it possible for an auditor to discover locations within a company procedure with weak or non-existent controls.

An illustration of technology that can be comprehended through flowchart investigation is company source organizing application this kind of as Oracle e-Enterprise Suite and SAP. Input controls are established through certain ‘rules’ to ensure the validity of information. Procedure controls are applied to large-risk capabilities, transactions or varieties. Output controls consist of studies and reconciliations.

Another illustration of intricate technology that can be comprehended by way of flowcharts is service oriented architecture (SOA). This architecture is composed of many web and computer software components that are built-in to hook up services providers with services consumers. ‘Web services’ help particular organization procedures. Every of these web solutions will typically have controls on knowledge inputs, processing and output. The flowchart is crucial to realize such web solutions and their integration in a broader setting normally by way of an Enterprise Support Bus (ESB).

In summary, a flowchart can be utilised by IT auditors to analyze a organization process. Different facets of the process can be emphasised these kinds of as risks, controls, interfaces, selection details, engineering infrastructure and parts. flowchart software of a image is equal to a thousand terms is accurate. A flowchart can seize crucial details that verbiage and textual content are not able to easily match. We inspire the IT audit, chance and manage communities to use this effective resource in doing their respective capabilities.
