Which of the following describes 'noun concepts'?

Noun concepts refer to entities or objects that are the focus of interest within a given context, especially in business analysis. These are tangible or identifiable elements that serve as the foundation for understanding the structure and processes of a system.

In this case, options like "Customer" or "Order" are prime examples of noun concepts, as they encapsulate specific entities that can be categorized and analyzed. Identifying such noun concepts is crucial in requirement analysis because they help in defining the scope of the system and guide the development of functional and non-functional requirements.

The other options mainly refer to actions (dynamic actions taken by users), methodologies (process steps in a project plan), or analytical outcomes (valuable insights from past reporting), which do not align with the definition of noun concepts. These elements are important in different contexts within project management and analysis, but they do not embody the notion of noun concepts, which are inherently more static and representative of the core elements being worked with.
