- Gulf of execution
Gulf of execution is a term usually used in
human computer interactionto describe the gap between a user's goal for action and the means to execute that goal. Usabilityhas as one of its primary goals to reduce this gap by removing roadblocks and steps that cause extra thinking and actions that distract the user's attentionfrom the taskintended, thereby preventing the flow of his or her work, and decreasing the chance of successful completion of the task. Similarly, there is a gulf of evaluationthat applies to the gap between an external stimulus and the time a person understands what it means. Both phrases are mentioned in Donald Norman's 1986 book "User Centered System Design: "
This can be illustrated through the discussion of a
VCRproblem. Let us imagine that a user would like to record a television show. They see the solution to this problem as simply pressing the "Record" button. However, in reality, to record a show on a VCR, several actions must be taken:
# Press the record button.
# Specify time of recording, usually involving several steps to change the hour and minute settings.
# Select channel to record on - either by entering the channel's number or selecting it with up/down buttons.
# Save the recording settings, perhaps by pressing an "OK" or "menu" or "enter" button.
The difference between the user's perceived execution actions and the required actions is the gulf of execution.
