Discuss ISTQB CT-UT Exam Topic 7 Question 18

You're defining usability test tasks for a web shop for mobile phones and smartphones. Finding out whether users are able to place an order easily has been identified as the main goal of the usability test.

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?

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.

D seems irrelevant to the task of placing an order. It doesn't really test usability in the context of the shopping experience.

Elly 3 months ago

I think C is too detailed. It might lead users through a scripted process instead of letting them explore naturally.

Lindsay 3 months ago

I'm not sure if A is specific enough. Just saying "put the first phone in your cart" feels too vague for a usability test.

I remember we discussed how task definitions should reflect real user scenarios. Option B seems to fit that well.
