Which solution scope technique can help the business analyst understand the scope of the work by breaking down the scope into smaller work products?

Interface analysis focuses on identifying and defining the interactions between systems or components, not on breaking scope into smaller work products.

User stories are a requirements elicitation and documentation technique used to capture functionality from a user perspective, not a scope decomposition technique.

Functional decomposition systematically breaks down a complex scope into smaller components or work products, making it easier for the business analyst to understand, plan, and manage the work. It decomposes deliverables hierarchically until each piece is small enough to be analyzed or assigned, directly addressing the need to understand scope through breakdown.

Scope modeling visually represents the boundaries of a solution but does not specifically involve breaking scope down into smaller work products.
