Core Software Development Life Cycle (SDLC) Phases
1. Planning and Requirement Gathering
The first phase involves defining the project scope, identifying functionalities, and understanding user needs. This step is crucial for setting the project’s foundation and ensuring all stakeholders align on the objectives.
2. Design and Architecture
During this phase, the gathered requirements are translated into a technical blueprint. This includes designing the system architecture, selecting technologies, and creating detailed design documents that guide development.
3. Development and Implementation
In this phase, developers start coding based on the design specifications. This is where the software takes shape, with developers writing the code to create the functionalities defined in the planning phase.
4. Testing and Quality Assurance
Testing and quality assurance are critical for identifying and rectifying bugs. This phase ensures that the software meets the required standards and functions correctly. Various testing methods, including unit testing, integration testing, and system testing, are employed to validate the software.
5. Deployment and Release
Once the software has passed the testing phase, it is deployed to the production environment and operationalized for users. This phase involves installation, configuration, and user training to ensure a smooth transition.
6. Maintenance and Support
Post-release, the software enters the maintenance phase. This involves addressing issues, implementing updates, and making necessary enhancements to keep the software functional and relevant.
Popular SDLC Methodologies
Waterfall Model
The Waterfall model is one of the oldest SDLC methodologies. It is structured and predictable, following a linear sequence of phases. Each phase must be completed before the next begins, making it easy to manage and document. However, its rigidity can be a drawback, as it does not accommodate changes well once the process is underway.
Agile Methodology
Agile is a highly adaptable and iterative methodology. It emphasizes flexibility and continuous improvement, with development divided into short cycles called sprints. Agile requires strong communication and collaboration within the team, and while it is excellent for small to medium projects, it might be challenging to implement in larger, more complex projects.
Model
The iterative model combines the structure of Waterfall with the flexibility of Agile. Development is done in small iterations, allowing for incremental improvements and adjustments based on feedback. This approach requires good planning and risk management to be effective.
Spiral Model
The Spiral model is risk-focused and iterative, making it suitable for large and complex projects. It emphasizes identifying and mitigating risks at each iteration or “spiral,” ensuring that potential issues are addressed early. However, this model can be resource-intensive and complex to manage.
Kanban
Kanban is a visual workflow management methodology that emphasizes efficiency and continuous delivery. It uses a board with columns to represent different stages of development, allowing teams to track progress visually. Kanban effectively manages workflows but may have limited scope for large projects with complex requirements.
Scrum
Scrum is a popular Agile framework that uses time-boxing development sprints to deliver incremental improvements. It focuses on flexibility and team collaboration, with roles such as Scrum Master and Product Owner guiding the process. While Scrum is highly effective for focused teams, it requires a dedicated team and may not suit projects with unpredictable requirements.
