The Software Development Lifecycle (SDLC) is a structured process that guides the creation of high-quality software in a systematic and cost-effective way. Understanding each phase is critical to building robust, scalable, and maintainable software.
1. Planning
“Measure twice, cut once.”
Goal: Define objectives, assess feasibility, estimate cost and timeline.
- Gather initial requirements from stakeholders.
- Conduct feasibility studies (technical, operational, financial).
- Develop a project plan and select methodologies (Agile, Waterfall, etc.).
2. Requirements Analysis
“What exactly should the software do?”
Goal: Understand user needs and document detailed functional and non-functional requirements.
- Interviews, surveys, user observation.
- Create Software Requirements Specification (SRS).
- Ensure alignment between business and technical teams.
