What is Functional Architecture?

Functional architecture, also called functional decomposition, is a method of breaking down a complex system into smaller, more manageable components. The goal of functional architecture is to identify the key functions that a system must perform and organize these functions into a hierarchical structure that reflects the relationships between them.

A functional architecture will typically begin with a top-level function that represents the overall purpose of the system, such as providing a specific service or product. This function is then broken down into a series of sub-functions, each of which corresponds to a specific aspect of the overall function. Each sub-function can be further broken down into a set of sub-sub-functions, and so on until the system is decomposed into a set of atomic functions, which can be implemented directly.

The functional architecture provides a clear and comprehensive view of the system, making it easier to understand its overall design and how its components are interconnected. It also allows for easier management and maintenance of the system, as well as future improvements or scalability.

Functional architecture can be applied in various fields like software engineering, systems engineering, and product design, where a complex system or a product is to be designed, built, and maintained. The functional architecture allows for the specification of the functional requirements of a system, provides a clear and comprehensive view of the system and enables the design of functional interfaces and interfaces among the different system elements.
