When a flowchart is designed so that a user must make decisions at various steps, the available options should be displayed in some consistent order from step to step.
Additional Information:
For example, 'yes' might always be on the left and 'no' on the right. Another scheme is always to have the desirable path lead downward and the 'problem' paths lead out to the side. Consistent ordering will permit a user to review a flowchart more quickly.
