Notes

Basically, it is a way to transform or decompose the complex part so that we can gain a better understanding of the complexity. Decomposition enables stakeholders to estimate the complexity of larger systems into smaller parts by tracking and quantifying the steps involved in the development of an organization's system. The links and relationships between all aspects of a functional relationship are examined in this technique, which facilitates the tracking of requirements and design changes.
STRENGTH:
Solution tool for resolving problems
It provides an in-depth understanding of the process of developing systems component parts
LIMITATION
Requires high level of expertise for the business analyst.
An effective functional decomposition requires a deep understanding of the requirements and extensive collaboration with stakeholders.
Requirements or their relationships with designs can often be difficult to decompose
