DOCUMENTING ACCOUNTING INFORMATION SYSTEMS
Discussion Questions
5-1. The chapter provides ten reasons why documenting AISs is important: (1) depicting
how the system works, (2) training users, (3) designing new systems, (4) controlling systems
existing system, and (3) to provide design specifications to outside vendors who might be
proposing new systems.
control weaknesses that are not apparent from prototypes or not obvious when observing a
system in use.
5-2. Document flowcharts mostly depict the physical flow of paper documents through a
system. Document and system flowcharts are similar in that they use similar symbols, although
Accountants can use data flow diagrams (DFDs) to depict the physical flows of data through an
AIS (like document flowcharts), or the logical flow of data through an AIS (like system
Program flowcharts tend to depict the most detailed level of system flowcharts because they
outline the logic sequence for a particular application program. Thus, they are more used by
5-3. A document flowchart is a pictorial representation of the physical data flow through
the various departments of a business. A document flowchart is used in designing or evaluating
an accounting information system.

1. A systems analyst uses it when evaluating a system to see if each department is receiving
others.
2. A system designer uses it when managers wish to improve or replace an existing system.
4. An auditor uses it to help define, follow, and evaluate an audit trail.
5. An internal data security expert uses it to identify weaknesses in the internal controls or
data processing of an accounting system.
5-5. Data flow diagrams use a square symbol to show the source or destination of data, a
circle to indicate a process, an open rectangle symbol to indicate a store of data, and arrows to
depict a data flow or data stream.
5-6. Developers create data flow diagrams in a hierarchy called the top-down approach to
systems development. In this approach, developers create these diagrams in levels, beginning
revisions are common, and little is considered “final” until the lowest diagram levels have been
specified and approved.
5-7. It is usually easier to follow logic with a chart or figure than with a written narrative.
the use of arrows to show connections or data flows.
5-8. Decision tables outline the set of conditions that a given processing task might
encounter and indicate the appropriate action to take for each condition. Decision tables can
because a computer program fails to account for a specific set of conditions. Finally, those
accountants who audit AISs rely heavily upon internal documentation, and decision tables can

5-9. Just as word processors enable users to create, store, modify, and print word
documents, CASE tools enable IT and accounting personnel to create, store, modify, and print
flowcharts. Most also include generators for developing data dictionaries.
not use such capable and time-saving tools.
5-10. End user computing refers to the computer activities of non-computer employees,
especially the development of large spreadsheets and databases. Although such activities are
descriptions, tutorials, and reference materials that other users need in order to run the
applications effectively. At one company known to the authors, important spreadsheets must be
