Choose a System/Software Development Life Cycle (SDLC) model and methodology, then apply this model and methodology to a project related to Information Technology (IT) you discussed in your Week 1 paper. Clearly define the SDLC model and methodology, and identify which SDLC step corresponds to each component of your project. Your paper should follow APA 6th edition formatting, including a title page and a references page with five scholarly sources. The content should be between three to five pages, not including the title and references pages. Your submission will be checked via SafeAssign for originality. Use appropriate scholarly language, provide in-depth analysis, and ensure proper citations throughout the paper.

Paper For Above instruction

The selection and application of a System Development Life Cycle (SDLC) model and methodology are crucial steps in ensuring the successful design, development, and deployment of information technology projects. For this assignment, I have chosen the Waterfall SDLC model, a traditional and linear approach, and will apply it to a project involving the development of an enterprise customer relationship management (CRM) system. This paper will define the Waterfall SDLC model and methodology, and systematically link each phase of the model to specific project components outlined in my Week 1 IT project.

The Waterfall SDLC model is characterized by a sequential, phase-based process where each phase must be completed before moving to the next. This approach emphasizes thorough planning, strict documentation, and a linear flow of activities, making it suitable for projects with well-defined requirements and low likelihood of scope changes (Royce, 1970). The methodology involves distinct stages: requirements analysis, system design, implementation, integration and testing, deployment, and maintenance (Newsom, 2011). In applying this to the CRM project, I will delineate each phase and specify the corresponding project components.

Requirements Analysis Phase

The first phase involves gathering and documenting detailed user requirements. For the CRM system, this includes understanding the needs of sales, marketing, and customer service departments, such as data management, reporting capabilities, and integration with existing systems. This phase sets the foundation for subsequent design and development by ensuring all stakeholders' needs are accurately captured (Pressman & Maxim, 2014). In my project, requirements were obtained through interviews, surveys, and analysis of existing processes.

System Design Phase

Based on the requirements, the design phase involves creating detailed system specifications, including architecture design, data models, user interfaces, and security features. For the CRM system, this included designing the database schemas, user dashboards, and integration interfaces with email platforms and other tools. The design documents act as blueprints for developers and serve as reference points for ensuring the system aligns with user needs (Balzert, 1998).

Implementation Phase

The implementation phase involves actual coding and construction of the system components according to the design documents. Developers utilize programming languages, development tools, and methodologies suitable for the system’s requirements. In the CRM project, this phase included developing modules for contact management, lead tracking, and report generation. It emphasizes adherence to the design specifications and coding standards (Laplante, 2007).

Integration and Testing Phase

Post-implementation, the system undergoes integration testing to verify that all modules work cohesively and meet the specified requirements. This phase also involves identifying and fixing bugs. For the CRM, testing included usability testing, security testing, and performance assessment. This stage ensures that the entire system functions reliably before deployment and that issues are resolved proactively (Beizer, 1993).

Deployment Phase

Once testing confirms readiness, the system is deployed to the production environment. This involves data migration, user training, and establishing support mechanisms for end-users. In my CRM project, deployment included installing the system on servers, configuring user access, and conducting training workshops for users to familiarize them with new functionalities (Sommerville, 2016).

Maintenance Phase

After deployment, ongoing maintenance ensures the system operates smoothly, supports updates, and incorporates user feedback for improvements. This includes bug fixes, security patches, and adding features as organizational needs evolve. For the CRM system, maintenance was planned to be an ongoing activity managed by the IT support team, ensuring system longevity and relevance (Liu & Özsu, 2017).

Conclusion

The Waterfall SDLC model provides a structured approach suitable for projects with clear, unchanging requirements such as the CRM system example. By aligning each project component to specific SDLC phases, project management can maintain clarity, control, and systematic progress. This method ensures thorough analysis, careful design, and disciplined implementation, culminating in a reliable system that meets organizational needs and can be efficiently maintained over time.
