Mt. San Antonio College CISB11 System Development Life Cycle (SDLC The

The System Development Life Cycle (SDLC) is a structured methodology used for planning, developing, testing, and deploying information systems. This assignment aims to review the six phases of the SDLC and detail the tasks performed during each phase. Understanding these phases is essential for effective systems analysis and project management in information technology.

Paper For Above instruction

The System Development Life Cycle (SDLC) provides a systematic approach to developing information systems through a series of well-defined phases. These phases ensure that a project progresses smoothly from initial conception to successful implementation and maintenance. The six main phases of the SDLC are: Planning, Analysis, Design, Development, Testing, and Implementation & Maintenance.

1. Planning

The first phase, Planning, involves defining the scope of the project and determining its feasibility. Key tasks include gathering initial requirements and setting project goals. Conducting a feasibility study is also critical to evaluating economic, technical, operational, and schedule feasibility. During this phase, project managers allocate resources, develop initial budgets, and set schedules. The goal is to establish a clear understanding of what the project aims to achieve and whether it is achievable within constraints, ensuring all stakeholders are aligned.

2. Analysis

The Analysis phase focuses on understanding detailed business requirements by engaging stakeholders and end-users. Tasks include conducting interviews and collecting data to identify system needs comprehensively. System analysts document functional requirements, define system specifications, and create models such as data flow diagrams or use case diagrams. This phase ensures that the development team fully understands what the system must accomplish to satisfy user needs.

3. Design

The Design phase translates the requirements into technical specifications. Tasks here involve creating detailed system and software design documents, including architecture diagrams, interface designs, and database schemas. Designers determine hardware and software specifications, ensuring the design aligns with organizational standards. Prototyping may also be used to visualize and refine system functionalities before development begins.

4. Development

In the Development phase, actual coding occurs based on detailed design documents. Tasks include programming, code review, and documentation of the system components. Developers write source code, integrate system modules, and create database structures. This phase requires close collaboration and adherence to coding standards to ensure quality and maintainability of the software. Version control tools are often used to manage code changes.

5. Testing

The Testing phase verifies that the developed system functions correctly and meets specified requirements. Tasks include executing various tests such as unit testing, integration testing, system testing, and user acceptance testing (UAT). Identifying and fixing bugs or errors is essential at this stage. Testing ensures the system operates reliably, performs well under different scenarios, and aligns with user expectations before deployment.

6. Implementation & Maintenance

The final phase involves deploying the system to users through methods such as phased, direct cutover, or parallel implementation. Tasks include training users, data migration, and ensuring system stability. After deployment, the system enters the maintenance phase, which involves ongoing support, troubleshooting, and updates to address evolving business needs. Regular maintenance ensures the system remains current, efficient, and secure over time.

Conclusion

The SDLC provides a comprehensive framework that guides the development of information systems from conception through deployment and maintenance. Each phase includes specific tasks that collectively ensure the successful delivery of a functional and reliable system. Mastery of these phases helps IT professionals manage projects effectively, mitigate risks, and deliver solutions that meet organizational goals.
