1. Goal Structure for this step.

1.1 Correct Goals. What are the current goals for this point in the interaction ? Describe as for initial goals.

• What percentage of users will not have these goals, based on the analysis at the end of the previous step ?
• Check each goal in this structure against your analysis at the end of the previous step.
• Based upon that analysis, will all users have dropped it or failed to form it ?
• Also check the analysis at the end of the previous step, to see if there are unwanted goals, not appropriate for this step, that will be formed or retained by some users. (%, 0, 25, 50, 75, 100)

2. Choosing and executing the action.

Correct action at this step ?_________________________________________________________

2.1 Availability. Is it obvious that the correct action is a possible choice here ? If not, what percentage of users might miss it ? (%, 0, 25, 50, 75, 100)

2.2 Label. What label or description is associated with the correct action ?

2.3 Link of label to action. If there is a label or description associated with the correct action, is it obvious, and is there a good match between the label and the user's representation? If not, what percentage of users might have trouble? (%, 0, 25, 50, 75, 100)

If in doubt, talk to your users!

2.4 Link of label to goal. If there is a label or description associated with the correct action, is it obviously connected with one of the current goals for this step ? How ? If not, what percentage of users might have trouble ? Assume all users have the appropriate goals listed in Section 1. (%, 0, 25, 50, 75, 100)

2.5 No Label. If there is no label associated with the correct action, how will users relate to this action to the current goal. What percentage of users might have trouble with this ? (%, 0, 25, 50, 75, 100)

2.6 Wrong Choices. Are there other actions that might seem appropriate to some current goal ? If so, what are they, and what percentage of users might choose one of these ? (%, 0, 25, 50, 75, 100)

2.7 Too many choices. Are there more than 10 screen actions to be considered at this time?

2.8 Time-out. If there is a time-out in the interface at this step does it allow time for the user to select the appropriate action ? How many users might choose one of these ? (%, 0, 25, 50, 75, 100)

2.9 Hard to do. Is there anything physically tricky about executing the action ? Is so, what percentage of users will have trouble ? (%, 0, 25, 50, 75, 100)

Assume the correct action has been taken. What is the system's response ?

• Will users see that they have made progress towards some current goal ?
• What will indicate this to them ?
• What percentage of users will not see progress and try to quit of backup ? (%, 0, 25, 50, 75, 100)

• List all current goals that have been accomplished.
• Is it obvious from the system response that each has been accomplished ?
• If not, indicate for each, how many users will not realise it is complete. (%, 0, 25, 50, 75, 100)

• Are there any current goals that have not been accomplished, but might appear to have been based on the system's response ?
• What might indicate this ?
• List any such goals and the percentage of users will think that they have actually been accomplished. (%, 0, 25, 50, 75, 100)

• Is there any "And-Then "structure, and does one of its sub-goals appear to be complete ?
• If the sub-goal is similar to the super-goal estimate how many users may prematurely terminate the "and then " structure.

• Does the system response contain a prompt or cue that suggests any new goals ?
• If so, describe the goals.
• If the prompt is unclear, indicate the percentage of users who will not form theses goals. (%, 0, 25, 50, 75, 100)

• Are there any other new goals that the user will form given their current goals, the state of the interface, and their background knowledge ?
• Why ? If so, describe the goals, and indicate how many users will form them. NOTE that these goals may or not be appropriate, so forming them may be bad or good. (%, 0, 25, 50, 75, 100)
