7.3.2-5 Resumption of Interrupted Sequences

A minimum number of actions should be required to resume a control-action sequence that was temporarily suspended.

Additional Information:
When a user has interrupted a sequence of operations, a minimum number of actions should be required to resume it. The user should not be required to restart the sequence from the beginning. One way of supporting the user in finding a display containing a suspended task is to have a 'previous display' feature that accesses a sequence of previous displays. A second approach is an interaction history feature that lists previously accessed displays and provides access to them. A third method is to include a 'bookmark' feature allowing users to designate displays containing tasks that are in progress. Thereafter, few actions or none should be required to resume the task.
