Difficulty: Medium
Correct Answer: it focuses on the physical aspects of the system
Explanation:
Introduction / Context:
Structured methods (e.g., DFDs, ERDs, structure charts) emphasize logical modeling before physical design. They promote clarity, user involvement, and progressive elaboration of documentation. Identifying a statement that contradicts these principles reveals misconceptions about the approach.
Given Data / Assumptions:
Concept / Approach:
Because structured analysis focuses first on logical requirements, saying it “focuses on the physical aspects” mischaracterizes the approach. Physical design (file structures, hardware choices, detailed schemas) follows the logical models to preserve traceability and flexibility.
Step-by-Step Solution:
Review each option against structured method principles.Confirm that graphic specifications, thorough user study, and cumulative documentation are hallmarks of structured approaches.Identify the incorrect statement: focus on physical aspects.
Verification / Alternative check:
Methodologies like SSADM separate logical from physical design explicitly—evidence that physical focus is not an advantage in the analysis stage.
Why Other Options Are Wrong:
Option B reflects the visual nature (DFDs/ERDs). Option C reflects user-area study. Option D reflects layered documentation (context to detail). “None” is wrong because one option is indeed not an advantage.
Common Pitfalls:
Premature fixation on technology choices; sacrificing logical clarity for early physical optimizations can increase rework later.
Final Answer:
it focuses on the physical aspects of the system
