Answer
Correct Answer: objectives → outputs → inputs → transformation (information processor) → management
Explanation
Introduction / Context:Systems analysis is most effective when approached top-down: define what the system must achieve before deciding how it will achieve it. Establishing a logical sequence prevents premature design decisions and ensures alignment with organizational goals.
Given Data / Assumptions:
- We seek a sequence that starts from purposes and ends with implementation and control.
- “Transformation” denotes processes that convert inputs to outputs.
- “Information processor” is the mechanism (manual or automated) performing the transformation.
Concept / Approach:A common top-down flow is: objectives (why) → outputs (what results) → inputs (what resources/data are needed) → transformation/information processor (how) → management (control/feedback). This aligns with requirements-first design and classic control loops.
Step-by-Step Solution:
Start with objectives to anchor scope.Define required outputs that evidence the objectives.Identify inputs necessary to produce those outputs.Design the transformation/information processor that converts inputs to outputs.Specify management controls for monitoring and feedback.Verification / Alternative check:Systems engineering and structured analysis methods advocate requirements and outputs before process design, validating this order.
Why Other Options Are Wrong:
- Sequences that begin with outputs or management without objectives invert priorities.
- Placing inputs after management or outputs after inputs disrupts the logic of requirement derivation.
Common Pitfalls:Jumping straight to technology (“information processor”) before clarifying objectives and outputs leads to misaligned systems.
Final Answer: objectives → outputs → inputs → transformation (information processor) → management
