Description: The functional specification is a document that describes the expected behavior of a software application. This document is fundamental in the development process, as it establishes the foundations upon which the software will be built. It includes details about the features, functions, and constraints of the system, as well as user requirements and expected interactions. The functional specification acts as a bridge between developers and stakeholders, ensuring that everyone has a clear understanding of what is expected from the final product. Additionally, it facilitates planning and design, allowing development teams to identify potential issues before they become significant obstacles. In the context of software development in general, the functional specification may include details about resource configuration and process automation. In summary, the functional specification is an essential component in the software development lifecycle, ensuring that the final product meets user expectations and needs.
