Define Systems cycle approach.

The Systems Cycle Approach, also known as the Systems Development Life Cycle (SDLC), is a systematic and structured process used in information system development and management. It provides a framework for planning, creating, testing, deploying, and maintaining information systems. The approach is designed to ensure that the development and implementation of information systems align with organizational goals and meet user requirements. The Systems Cycle Approach typically consists of several phases, each with its specific tasks and objectives:

1. Planning Phase:

   • In this initial phase, project goals, scope, and objectives are defined. Stakeholders' requirements are gathered, and a feasibility study is conducted to assess the project's viability. Project planning involves estimating resources, costs, and timelines.

2. Analysis Phase:

   • The analysis phase focuses on understanding and documenting the current system, identifying user requirements, and defining system functionalities. Analysts create detailed documentation, such as use cases, data models, and system requirements specifications.

3. Design Phase:

   • The design phase involves transforming the requirements gathered in the analysis phase into a blueprint for the new system. System architects create detailed technical specifications, data models, and interface designs. This phase also considers security, scalability, and maintainability aspects.

4. Implementation Phase:

   • During implementation, the actual coding and programming of the system take place. Software developers and engineers build the system based on the design specifications. This phase also includes database development, user interface creation, and integration of system components.

5. Testing Phase:

   • The testing phase is crucial for ensuring that the system meets the specified requirements and functions as intended. Various testing types, such as unit testing, integration testing, and user acceptance testing, are conducted to identify and rectify defects.

6. Deployment Phase:

   • Once the system has passed testing, it is deployed for use. This involves installing the system in the production environment, migrating data, and ensuring that users are trained to use the new system effectively.

7. Maintenance and Support Phase:

   • The maintenance phase involves ongoing support, monitoring, and enhancement of the system. This includes addressing any issues that arise, applying updates, and incorporating new features or improvements based on user feedback.

The Systems Cycle Approach emphasizes a structured and iterative process, allowing for adjustments and refinements as needed. It promotes collaboration between stakeholders, including users, developers, and management, ensuring that the developed system aligns with organizational goals and user expectations. This approach is fundamental in managing the complexities of information system development and maintenance within an organization.
