Which of the following is not a part of systems analysis?

Question

BlackTom AI · Accepted Answer

Creating detailed design specifications is a design-phase activity, not an analysis-phase activity. Systems analysis focuses on understanding and specifying what the system must do (requirements and problems), while systems design translates those requirements into detailed technical specifications and architectures.

1. Relevant knowledge points and concepts
- Systems Development Life Cycle (SDLC) typically divides work into stages: feasibility study, systems analysis, systems design, implementation, testing, deployment, and maintenance.
- Systems analysis activities: define the problem, gather and document information requirements, analyze current systems and causes of problems, model processes and data, and evaluate alternative solutions.
- Systems design activities: produce detailed blueprints (design specifications), define architecture, data structures, user interfaces, and program/module specifications.

2. Step-by-step reasoning
- Examine each option and classify it by SDLC stage:
  a) Identifying information requirements — this is requirement elicitation, central to systems analysis.
  b) Identifying causes of the problem — root-cause analysis of the existing system is an analysis task.
  c) Evaluating the alternatives — comparing possible solutions is part of analysis and selection.
  d) Creating detailed design specifications — writing technical blueprints (e.g., database schemas, program modules) is a design activity, following analysis.
  e) Defining the problem — establishing scope and problem statement is the starting point of analysis.

3. Calculations
- No numeric calculations are needed; the classification above is the complete logical "calculation" mapping activities to phases.

4. Why the correct answer is correct
- Creating detailed design specifications belongs to the systems design phase: it involves translating requirements into implementable technical documents, which is explicitly after systems analysis. Therefore it is not part of systems analysis.

5. Why the other options are incorrect
- Each of the other four options (identifying information requirements, identifying causes, evaluating alternatives, defining the problem) are core analysis tasks concerned with understanding needs, problems, and selecting solutions.

6. Conclusion
- The correct answer is "Creating detailed design specifications," which matches the provided answer.
