Difficulty: Easy
Correct Answer: data-flow diagrams (detailed DFDs)
Explanation:
Introduction / Context:
Feasibility studies evaluate whether a proposed system is worthwhile before substantial design and implementation work begins. Knowing what belongs—and what does not—keeps early documentation lean and decision-focused.
Given Data / Assumptions:
Concept / Approach:
Early documents emphasize business justification and outline solution paths. While high-level context diagrams may appear, detailed data-flow diagrams are typically premature and can bias decision makers or waste effort if the project is not approved.
Step-by-Step Solution:
List required items: project identity, problem statements, options, cost-benefit estimates, schedule, and risks.Determine which item is a detailed design artifact: DFDs.Select “data-flow diagrams” as the exception.
Verification / Alternative check:
Stage-gate methodologies separate feasibility/business case (Gate 1) from detailed analysis/design (later gates) where DFDs and models are elaborated.
Why Other Options Are Wrong:
Common Pitfalls:
Over-investing in design before approval; presenting low-fidelity cost/benefit without clear assumptions; excluding risk and constraints.
Final Answer:
data-flow diagrams (detailed DFDs)
