Which of the following is a reasonable task definition to include in the test?

Aut the first phone you find in your shopping cart!

BYour phone broke and you're looking for a new smartphone. Your budget is 200$ and it should have an infrared sensor as you like to operate your home entertainment system with it. Find a suited smartphone and order it!

CEnter the item number ''1469483'' in the search box and click ''OK''. Put the first item in the cart by clicking ''add to bag''. Then, click on ''checkout'' in order to start the order process. After that, fill in the form and click on ''submit''.

DWhich mobile operating system do you prefer?

Show Suggested Answer

Suggested Answer: B

A well-defined usability task uses a realistic scenario and goal (''find a suited smartphone within your $200 budget with infrared sensor and order it''), without prescribing exact clicks. This lets you observe how users naturally navigate, search, and complete the order process - directly measuring the main goal of placing an order.

This seems like a straightforward question. I'd go with option B - it provides a realistic scenario that tests the user's ability to find a suitable product within a given budget and with a specific requirement.

I agree with Rosalia. Option C provides a clear path for users to follow and achieve the main goal of the usability test.

A is just lazy. 'Put the first phone you find' - what kind of instruction is that? Might as well tell them to close their eyes and click random buttons.

I'm not sure about option B. It seems too specific with the budget and infrared sensor requirement. It might not be relevant to all users.

C is way too detailed and specific. Usability tests should focus on the overall user experience, not nitty-gritty steps.

D is completely irrelevant to the main goal of the test, which is to assess the ordering process. Might as well ask about the user's favorite color.
