How to write an effective scenario and task
The scenario sets the stage for a self-guided while the task is the star of the show. Maybe you want a tester to search your website for an item to purchase or you would like them to fill out a form. Regardless of the activity, it should be written in a way that is straight forward and simple to follow.
Here are some examples of good scenarios and tasks:
Scenario: You just purchased a Nintendo Switch and are looking for inexpensive games to play with your friends. You plan to purchase at least two games.
Task: Search for Nintendo Switch games and using the filters, find the least expensive options. You want to add at least two multi-player games to your cart.
Scenario: You want to purchase tickets for a virtual concert coming up in the next month. You realize that you need to create an account first before you can search for your tickets.
Task: Create an account using the fake credentials provided in the special instructions. Be sure to leave at least one required field empty so that you can experience an error message during the experience. While you go through the task, be sure to comment on clarity of messaging.
