Structured design methodology (repeat): which graphic tool best depicts module hierarchy and calling relationships during design?

Introduction / Context:
This question revisits the distinction between analysis and design artifacts. In structured design, we focus on how software modules interact and pass control/data.

Given Data / Assumptions:

• Goal: represent modular decomposition and interfaces.
• Audience: designers and developers planning implementation.

Concept / Approach:
Structure charts are the canonical tool in structured design, showing hierarchical module relationships, parameters, and coupling. They guide implementation and testing plans.

Step-by-Step Solution:

Verification / Alternative check:
Design reviews typically require structure charts to assess cohesion/coupling.

Why Other Options Are Wrong:
DFDs and flowcharts target different concerns; a bare “module” list lacks relationships.

Common Pitfalls:
Overly deep hierarchies and tight coupling; refactor to improve cohesion.

Final Answer:
Structure chart
