Final answer:
All of the options provided are stages in the SDLC. These stages include planning, analysis, design, and implementation, each contributing to the systematic creation and upkeep of information systems.
Step-by-step explanation:
The stages in the Systems Development Life Cycle (SDLC) are essential for systematically creating and maintaining information systems. The options provided in the question are:
- Planning and investigation
- Analysis
- Design and acquisition
- Implementation, followup, and maintenance
- All of these are stages in the systems development life cycle
The correct response to the question is e) All of these are stages in the systems development life cycle. Each of the mentioned stages plays a critical role in the development of an information system:
- Planning and investigation: This initial stage involves identifying the need for a new or enhanced system, defining project goals, and planning the project.
- Analysis: During this stage, the current system's functionality and limitations are studied in detail to articulate the new system's requirements.
- Design and acquisition: This stage focuses on how the system will fulfill the identified requirements, including the design of software, hardware, and user interfaces.
- Implementation, followup, and maintenance: The final stage is when the system is built, tested, deployed, and maintained over time, with follow-up to ensure it meets the intended goals.
