Funksjonsnivået

Funksjonsnivået, also known as the functional level, refers to the level of abstraction in software development where the focus is on the functionality of the system rather than its implementation details. This level is concerned with what the system does, rather than how it does it. It is a crucial aspect of software architecture and design, as it helps in breaking down complex systems into manageable components.

At the functional level, developers define the system's requirements, use cases, and user stories. They identify the key functions and features that the system must perform. This level also involves creating high-level designs, such as use case diagrams and sequence diagrams, which illustrate the interactions between different parts of the system.

The functional level is typically the first step in the software development lifecycle. It sets the foundation for subsequent levels, such as the architectural level and the implementation level. By clearly defining the system's functionality, this level helps in ensuring that the final product meets the user's needs and expectations.

In summary, the functional level is an essential part of software development that focuses on defining what the system should do. It provides a clear understanding of the system's requirements and serves as a blueprint for the subsequent development phases.
