System Functional Model, also known as Function Modeling, is a popular problem-solving tool that helps us to model a problem using functional language and identify problematic and functional components. Functional modeling helps us to think within the scope of components and their functions instead of the system as a whole.
As part of many problem-solving projects, it is extremely important to understand the functional interactions between different components of the systems that you are analyzing. Functional modeling allows us to quickly describe and map the functionality of all components contributing to the final product or service of that system. The functional modeling tool is applicable to both sudden unpredictable deviations (also known as excursions) and solving chronic problems for consistent improvements.
Among many cases when Functional Modeling is useful for us as problem solvers and innovators, we want to highlight just a few:
