When combining top-down decomposition with bottom-up synthesis during analysis and design, the blended strategy is commonly called an:

Introduction / Context:
Top-down analysis breaks a complex problem into subsystems, while bottom-up focuses on composing reliable components into larger solutions. Many teams blend both views to gain clarity and reuse. This item asks for the recognized term for that combination.

Given Data / Assumptions:

• Top-down clarifies scope and responsibilities via decomposition.
• Bottom-up leverages existing components and patterns.
• The organization values both architectural guidance and pragmatic reuse.

Concept / Approach:
An integrative approach uses high-level decomposition to guide structure and uses bottom-up insights to validate feasibility, cost, and reuse opportunities. The result is a solution that is both coherent and grounded in available capabilities.

Step-by-Step Solution:
1) Recognize the two complementary strategies: top-down and bottom-up. 2) Identify a name that reflects synthesis and alignment. 3) Select 'Integrative approach' as it explicitly denotes integration of both.

Verification / Alternative check:
Method texts frequently describe integrative or hybrid approaches that marry decomposition with component reuse to balance clarity and practicality.

Why Other Options Are Wrong:
Option A: Interactive describes user interaction, not methodological synthesis.
Option B: Interpretive refers to meaning making, not structural integration.
Option D/E: Overbroad or inapplicable.

Common Pitfalls:
Treating the approaches as mutually exclusive. Successful teams oscillate between them as information evolves.

Final Answer:
Integrative approach
