The correct answer is: System Development Life Cycle (SDLC).
A System Development Life Cycle (SDLC) is a framework for planning, designing, developing, testing, and deploying an information system. It is a systematic approach to the development of information systems that ensures that all aspects of the system are considered and that the system meets the needs of the users.
The SDLC typically consists of the following phases:
- Planning: In this phase, the need for the system is identified and the scope of the project is defined.
- Analysis: In this phase, the current system is analyzed and the requirements for the new system are defined.
- Design: In this phase, the architecture of the new system is designed.
- Development: In this phase, the new system is developed.
- Testing: In this phase, the new system is tested to ensure that it meets the requirements.
- Deployment: In this phase, the new system is deployed to the users.
- Maintenance: In this phase, the new system is maintained and updated.
The SDLC is a flexible framework that can be adapted to the needs of the project. The number of phases and the activities within each phase can vary depending on the complexity of the system.
The SDLC is a valuable tool for developing successful information systems. It helps to ensure that the system meets the needs of the users, that it is developed in a timely and cost-effective manner, and that it is maintained and updated to meet changing requirements.
Here is a brief explanation of each option:
- CASE tool: A CASE tool is a software application that helps to automate the development of information systems. CASE tools can be used to generate code, create diagrams, and manage project documentation.
- Phased conversion: Phased conversion is a method of deploying a new system in which the system is rolled out to users in phases. This can help to minimize disruption to the business and to ensure that the system is properly tested before it is deployed to all users.
- Success factors: Success factors are the key elements that contribute to the success of a project. Success factors can vary depending on the project, but some common success factors include having a clear vision, having a well-defined plan, having the right team in place, and having adequate resources.
- Move of the above: This option is not a valid answer.
