The correct answer is: D. both (a) and (b).
System analysis is the process of identifying and defining the need for a new system, and then determining the requirements for that system. System design is the process of creating a detailed plan for how the system will work. Implementation is the process of building and deploying the system.
All three of these steps are necessary for a successful system study project. Without system analysis, the project team would not know what the system needs to do. Without system design, the project team would not know how to build the system. And without implementation, the system would not be able to be used by the people who need it.
Here is a brief explanation of each option:
- Option A: System analysis. System analysis is the process of identifying and defining the need for a new system, and then determining the requirements for that system. The goal of system analysis is to understand the current system and its problems, and to identify the needs of the users of the new system.
- Option B: System design. System design is the process of creating a detailed plan for how the system will work. The goal of system design is to create a system that meets the requirements of the users and that is feasible to build.
- Option C: Implementation. Implementation is the process of building and deploying the system. The goal of implementation is to create a system that works as designed and that can be used by the users.
- Option D: Both (a) and (b). System analysis and system design are both necessary for a successful system study project. Without system analysis, the project team would not know what the system needs to do. Without system design, the project team would not know how to build the system.
- Option E: None of the above. None of the options alone is sufficient for a successful system study project. All three steps are necessary.
