A flowchart uses the same shape for a decision point and a normal process. What problem will arise?

Correct answer: The difference in the functions of steps will not be clear

Flowcharts use standard symbols as a visual language: different shapes communicate different functions, such as an action or a decision. If one shape is used for both, the reader cannot immediately distinguish a branching decision from an ordinary process step. Thus, the functions of the steps become unclear. The error does not directly change colours, arrow size, or the physical size of the chart.
