ISTQB CT-UT Exam - Topic 6 Question 9 Discussion

Actual exam question for ISTQB's CT-UT exam

Question #: 9
Topic #: 6

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?

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.

I recall a practice question where we had to define tasks for an online store, and I feel like option B aligns best with that kind of realistic shopping experience.

I think option A is too vague. Just saying "put the first phone" doesn't really test usability effectively.

I'm not sure about task B. While it gives a good scenario, the specific budget and requirement for an infrared sensor might be too limiting. I'm wondering if a more open-ended task would work better.

Task A is way too simple and doesn't really test anything. Task D is just asking about preferences, not testing usability. I think task B is the best option here.

I'm not sure if option C is too detailed. It feels like it might lead users too much instead of letting them explore.

I remember we discussed how task definitions should reflect real user scenarios, so I think option B is a good choice.

I'm a little confused by task C - it seems overly specific and detailed. I'm not sure if that's the best way to test usability. I'm leaning more towards task B.

I'm feeling pretty confident about this one. I think task B is the most reasonable since it gives the user a realistic scenario and specific criteria to search for a phone that fits their needs.
