ISO 9241-11 provides guidelines for the design of user interfaces for software applications, including principles for user-centered design, task analysis, and usability testing.

The primary goal of usability engineering is to ensure that a product is easy to use, by considering the needs and capabilities of the users and designing the product accordingly.

A/B testing is a method for comparing two versions of a product to see which one performs better. It is not a common usability engineering method, as it is more focused on measuring the effectiveness of a product rather than its usability.

The purpose of a usability test is to evaluate the usability of a product, identify usability problems, and collect feedback from users. This information can then be used to improve the usability of the product.

Error prevention is not a common usability heuristic. It is a design principle that aims to prevent users from making errors in the first place. Usability heuristics are more focused on making it easy for users to recover from errors.

Usability is a subset of user experience. Usability is concerned with the ease of use of a product, while user experience is concerned with the overall experience of using a product, including factors such as enjoyment, satisfaction, and engagement.

Website traffic is not a common usability metric. It is a measure of the number of people visiting a website, but it does not provide any information about the usability of the website.

The purpose of a style guide is to ensure consistency in the design of a product. This includes things like the use of fonts, colors, and layout. A style guide helps to create a cohesive and professional look and feel for a product.

Project management software is not a common usability engineering tool. It is a tool for managing the tasks and resources involved in a project. Usability engineering tools are specifically designed to help evaluate and improve the usability of a product.

The purpose of a persona is to represent a typical user of a product, help designers understand the needs of users, and create a more realistic testing environment. Personas are based on research and data about the target audience for a product.

ANSI/HFES 100-2007 is not a common usability engineering standard. It is a standard for human factors engineering, which is a broader field that includes usability engineering.

A usability requirement is more specific than a usability goal. A usability goal is a general statement about what the product should be able to do in terms of usability, while a usability requirement is a specific statement about how the product should perform in terms of usability.

Marketing is not a common usability engineering activity. It is a business activity that is focused on promoting and selling a product. Usability engineering activities are focused on evaluating and improving the usability of a product.

The purpose of a usability inspection is to identify usability problems in a product. This is done by having a team of experts review the product and identify any potential usability problems.

A marketing plan is not a common usability engineering deliverable. It is a business document that is used to plan and execute marketing activities. Usability engineering deliverables are documents that provide information about the usability of a product.
