Do not use substeps to:

• Artifically keep the number of steps below a certain limit.

  It is better to use more standard steps than it is to add substeps unnecessarily.

• Organize steps around different elements in the UI.

  Guide the customer through the UI, one area at a time. The customer can only be in one area of the interface at a time, so splitting this information up into substeps adds little value.

• Cover multiple tasks in a single task topic.

  Where logical divisions exist, use separate topics for different tasks.

• Branch to another series of steps on which the current task is dependent.

  For example, instead of using substeps to introduce prerequisite steps, put them in a separate topic.
