Using Flowcharts Inside IT Audit Involving Essential Purposes

A flowchart can be very beneficial in auditing crucial company apps and techniques this kind of as enterprise useful resource preparing programs (ERP) and provider oriented architecture (SOA) systems. As IT auditors we are anxious with getting a distinct comprehending of the pitfalls and controls in the technologies beneath review. Flowcharts facilitate an precise evaluation of an IT surroundings.

According to Wikipedia, the standard definition of a flowchart is a type of diagram that signifies an algorithm or approach that demonstrates info and its movement normally with arrows. The use of flowcharts is widespread in a lot of fields for evaluation, design and style, documentation and process administration.

Flowcharts are most helpful to visually display business procedures and the supporting technological innovation. Auditors can concentrate on distinct elements of data flows and infrastructure in these diagrams relying on the assessment of risks and controls.

4 basic designs are commonly employed to generate flowcharts. A square is employed for a approach (e.g. incorporate, exchange, conserve). A square with a wavy foundation is used for a document. A diamond is utilized for a selection stage (e.g. of course/no, accurate/untrue). A sideways cylinder is utilised for information storage (e.g. databases). These standard styles ended up at first set up by IBM and other pioneers of data technology.

Further designs incorporate circles, ovals and rounded rectangles for the start off and finish of a enterprise method. Arrows show ‘flow control’ among a resource symbol and a concentrate on symbol. A parallelogram represents enter and output e.g. knowledge entry from a kind, screen to person.

In creating flowcharts, there are some basic policies to adhere to. Start and stop points must be obviously defined. The degree of element documented in the flowchart need to be appropriate to the matter issue lined.

Output controls consist of studies and reconciliations.

Yet another case in point of complicated technologies that can be comprehended through flowcharts is provider oriented architecture (SOA). This architecture is made up of numerous internet and software elements that are integrated to link service vendors with service consumers. ‘Web services’ assistance distinct company procedures. Every single of these net solutions will typically have controls on information inputs, processing and output. The flowchart is essential to recognize such world wide web companies and their integration in a broader atmosphere generally by way of an Business Service Bus (ESB).

In summary, a flowchart can be utilised by IT auditors to evaluate a organization process.
