Users should be permitted to request a summary of prior entries to help determine present status, and should be allowed to review the parameters currently in effect.
Additional Information:
Summarizing prior entries will be particularly helpful in tasks where the sequence of user actions is variable, where a user must know what was done in order to decide what to do next. Summarizing prior entries may not be needed for routine transactions if each step identifies its predecessors explicitly, although even in those circumstances, a user may be distracted and at least momentarily become confused. A capability for parameter review may likewise be helpful even when a user selects all parameters personally.
