I am building an app which provides users information about stocks and allows users to follow stock development by adding them to their favourites. I am planning a usability test and have checked some resources: Link 1 and Link 2. I have two questions.
- Closed or open-ended tasks? For example, I could have tasks like:
- Search for a stock X and add it to your favourites (a closed task).
- Search any stock from industry A and add it to your favourites (an open-ended task).
Which is better, or would it be good to include both types? I want for users to be able to explore the app a bit by themselves without too much limitations (open-ended), but I am worried if tasks then become too vague.
- Actionable or verbal goals? For example, I could have something like:
- Check the info of a stock X, what do you think is the current status of this stock?
Link 1 talks about always having actionable tasks. However, I also want to test how users understand and interpret displayed information. So the goal in these type of tasks would be verbal, but I am not sure is this a good idea.
