There are many other tools for documenting AISs besides document flowcharts, system flowcharts, processmaps, and data flow diagrams. Two of them are (1) program flowcharts, and (2) decision tables.

Accountants should have some familiarity with these tools, however, because they may see them—for example, when reviewing the design for a revised accounting system.
