2. To divide high-level concepts into manageable parts for analysis

3. To assess team performance during the project

4. To define the project scope in monetary terms

The correct answer is: To divide high-level concepts into manageable parts for analysis

The main function of a Decomposition Model is to divide high-level concepts into manageable parts for analysis. This approach is vital in the realm of business analysis and project management because it allows teams to break down complex tasks or requirements into smaller, more manageable components. By doing so, stakeholders can better understand the individual elements that contribute to a larger goal, leading to more effective planning, resource allocation, and evaluation of progress. When high-level concepts are decomposed, it enables clearer analysis and assessment of each individual component, ensuring that nothing is overlooked. This detailed breakdown helps in identifying specific requirements, risks, and opportunities that may not be apparent when viewing the project or concept as a whole. Ultimately, this structured approach supports better decision-making and enhances the overall quality of project delivery.
