It is important to clearly describe logical control structures that involve branching away from the simple sequential flow of steps and the conditions upon which they are based. Outlines are well suited to this task because of the hierarchical nature of their lettered and numbered steps. Analysts often employ indentation using tabs or spaces to help clarify step subordination. If your rendering software cannot indicate the presence of such "whitespace" characters, be give careful attention to the labeling of the steps to determine the subordination of the steps.
