Each question shows the correct answer and an explanation of why it is right
You are asked to evaluate the usability of a software application for a law firm. Due to time and budget constraints, it is not possible to include users in the evaluation process.
Which of the following is a valid approach for evaluating the usability in this case?
When direct user involvement isn't feasible, an expert-based usability review (such as a heuristic evaluation or cognitive walkthrough) allows evaluators to systematically identify usability issues by applying established guidelines and their domain expertise.
Which of the following are common mistakes made in usability testing?
i. The user is too active
ii. Critical results are ignored
iii. No observers involved
iv. Scheduling too late
v. Incorrect focus
Common pitfalls include overlooking critical findings (ii), scheduling tests too late in the development cycle (iv), and having the wrong evaluative focus (v). Neither ''the user is too active'' (i) nor ''no observers involved'' (iii) are typical mistakes in standard usability-testing practice.
During a usability test, a user suggested that a quick search box on every page would help a lot for several of the main tasks. You added this finding to the list.
What's the correct classification for these kinds of findings?
A user's spontaneous suggestion for a new feature (a search box on every page) isn't an existing defect or a positive highlight of the current design - it's a ''good idea'' for potential enhancement.
What is the System Usability Scale (SUS)?
The SUS is a standardized questionnaire with ten statements rated by users, yielding a single score that reflects overall perceived usability - widely used for quick benchmarking across systems.
What is a usability test task?
A usability test task is the specific action or goal you ask a participant to perform during the session - defined by the moderator, time-bounded, and designed to reveal how easily users accomplish realistic objectives with the product.
You're redesigning the web shop of a customer and found out that they are using legacy web design techniques like html tables for design matters, making the website hard to be operated using alternative input and output devices (e.g. screen readers).
Which kind of risk is most likely to occur?
Using layout tables rather than semantic markup undermines compatibility with assistive technologies - like screen readers and alternative input devices - creating barriers for users with disabilities. This directly constitutes an accessibility risk.
What does the Equality Act address?
The Equality Act consolidates previous anti-discrimination laws in the UK, prohibiting unfair treatment based on protected characteristics - such as age, disability, gender reassignment, race, religion, sex, or sexual orientation - both at work and in broader public life.
