Usability Engineering

What is the primary definition of usability according to the Interaction Design Foundation?

• A measure of how attractive design is to users

• A measure of how well a specific user in a specific context can use a product or design to achieve a defined goal effectively, efficiently and satisfactorily

• A measure of the cost-effectiveness of a product

• A measure of the technical complexity of a product

According to Nielson (1993), what does usability assess?

• The speed of a product's development

• How easy user interfaces are to use

• The market value of a product

• The technical specifications of a product

Which of the following is NOT a key component of usability?

• Learnability

• Efficiency

• Memorability

• Profitability

What is the focus of usability engineering?

• Developing the most cost-effective software

• Providing structured methods for achieving usability in user interface design during product development

• Maximizing the number of features in a product

• Ensuring the product meets all technical specifications

Why is a structured process important is usability engineering?

• It focuses solely on the technical aspects of the product

• It reduces the need for user feedback

• It ensures that the design is based on systematic understanding and prediction of user behavior

• It guarantees a higher profit margin

Which stage in the Usability Engineering lifecycle involves creating multiple design sketches simultaneously?

• Know the user

• Goal settings

• Parallel design sketches

• Final released product

What is the purpose of participatory design in usability engineering?

• To minimize the cost of development

• To involve users directly in the design process to ensure their needs and preferences are considered

• To finalize the technical specifications of the product

• To conduct market research

What is formative testing in the context of usability engineering?

• Assessing the financial viability of the product

• Analyzing the market trends for usability standards

• Conducting usability tests during the design process to identify and fix usability issues

• Testing the final product after it has been released

Which of the following benefits is NOT directly associated with Usability Engineering?

• Reducing the need for customer support

• Saving costs by identifying design issues early

• Improving product quality through usability checks

• Guaranteeing a higher sales volume

What is the role of iterative design in the Usability Engineering lifecycle?

• To finalize the product design in one step

• To continuously refine and improve the design based on user feedback and testing results

• To increase the complexity of the design

• To ensure that no changes are made after the initial design
