A decision table would not be an appropriate way to visualize and understand this set of activities. A decision table is used as an aid in making decisions. A decision table shows possible sets of conditions and the actions resulting from them when the logic can be easily presented in table format. They can also be used to verify the completeness and consistency of a process involving different actions under different conditions. Decision tables work better than decision trees for very complex or extensive sets of conditions.
A program flowchart would not be an appropriate way to visualize and understand this set of activities. A program flowchart demonstrates how a program works within a system. Using boxes of different shapes and arrows, it shows all user-interaction pathways. Program charts can be very large and complex. However, they are useful for mapping an entire program.
A Gantt chart is a type of bar chart used to illustrate a schedule for a project with several tasks, each of which has a start and finish date, and some of which may depend on the previous completion of another task. In a Gantt chart, a project is divided into parts and activities or tasks that are plotted on a chart with the tasks listed on the left side and time across the top or bottom. The tasks are then placed into the time frame during which they need to be completed, showing their start and finish dates. Gantt charts can be used to show current project status using percentage-complete shadings in the bars. A Gantt chart would not be an appropriate way to visualize and understand this set of activities, because the various activities as described here are ongoing. They don't have specific start and finish dates.
A document flowchart would be the best way to visualize and understand this set of activities. A flowchart is used to show visually the stages of a process. Flowcharts are usually used in computer systems or other business applications. They provide step-by-step information to help the people using them understand the steps of a project or a system. A document flowchart traces the movement of a document, such as an internal memo, payroll information or interoffice mail, through a system. It shows how a document passes from one part of the company to another.
