Study Notes

System Documentation Technique

Accountants need to be able to read system documentation and understand how a system works.
The Sarbanes-Oxley Act (SOX) requires companies to assess internal controls and auditors to evaluate those assessments.
System documentation is used during system development and for making changes to a system.

Business Process Diagrams

Business Process Diagrams (BPD) are visual representations of activities in a business process.
BPD's are designed to be easily understood by all business users using a standard notation, BPMN: Business Process Modeling Notation.
BPD's can include the organizational unit performing a given activity.

Data Flow Diagrams (DFD)

DFD's focus on the data flows in processes, the sources and destinations of data, and data stores.
DFD's are visually simple and can be used to represent the same process at both a high-level and in detail.

Flowcharts

Flowcharts describe an information system by showing inputs and outputs, information activities, data storage, data flows, and decision steps.
Flowcharts are effective at capturing control via decision points and showing manual vs. automated processes.

Types of Flowcharts

Document flowcharts: show the flow of documents and data in a process, and aid in evaluating internal controls.
System flowcharts: depict the data processing cycle of a given process.
Program flowcharts: illustrate the sequence of logic in a system process.

Guidelines for Drawing Flowcharts and DFD's

Flowcharts
- Understand the system you are trying to represent.
- Identify business processes, documents, data flows, and data processing procedures.
- Organize the flowchart to read from top to bottom and left to right.
- Clearly label all symbols.
- Use page connectors if the diagram cannot fit on a single page.
- Edit, review, and refine the flowchart to make it easy to read.
DFD's
- Identify and understand the business process.
- Decide the level of detail (summary or detailed DFD).
- Organize using as many rows as needed to explain the process.
- Enter each business process showing where it begins and ends.
- Draw a rough sketch, refine, and finalize.
