Which of the following actions can be suggested by verb concepts?

Verb concepts are essential in requirement analysis as they represent actions that can be taken concerning requirements or processes. Each of the choices reflects different actionable verbs indicative of various activities in requirement elicitation, documentation, and implementation.

Defining requirements involves clearly outlining what is needed and establishing boundaries for the project or product. This is a crucial first step in understanding stakeholder needs.

Revising implies making changes or modifications to existing requirements, which is vital for ensuring that the requirements remain relevant and effective as the project evolves.

Creating involves the development of new requirements, which is pivotal when new needs emerge or when innovating solutions to problems.

Since all these actions—defining, revising, and creating—are integral components of the requirements management process, suggesting that all can be represented by verb concepts accurately captures the breadth of activities necessary for successful requirement analysis. Hence, the correct answer encompasses the comprehensive nature of actions that can be indicated by verbs in this context.
