Software Development Life Cycle (SDLC)
The Software Development Life Cycle (SDLC) is a structured process used by software developers and project managers to design, develop, test, and deploy software applications. SDLC provides a roadmap for managing the entire lifecycle of a software project, from initial concept through to final deployment and maintenance. The SDLC is typically divided into several phases, including planning, requirements analysis, design, implementation (coding), testing, deployment, and maintenance. Each phase has specific deliverables and milestones, ensuring that the project stays on track and meets its objectives.
Different SDLC models exist, such as Waterfall, Agile, Spiral, and V-Model, each with its own approach to managing the development process. For example, the Waterfall model follows a linear, sequential approach, while Agile emphasizes iterative development and continuous feedback. The choice of SDLC model depends on factors like project size, complexity, and requirements. By following a well-defined SDLC, teams can improve the quality of their software, reduce risks, manage resources effectively, and deliver products that meet customer needs.
How CodeBranch applies Software Development Life Cycle (SDLC) in real projects
The definition above gives you the concept — but knowing what Software Development Life Cycle (SDLC) means is different from knowing when and how to apply it in a production system. At CodeBranch, we have spent 20+ years building custom software across healthcare, fintech, supply chain, proptech, audio, connected devices, and more. Every entry in this glossary reflects how our engineering, architecture, and QA teams actually use these concepts on client projects today.
Our work combines AI-powered agentic development, the Spec-Driven Development (SDD) framework, CI/CD pipelines with agent rules, and production-grade quality gates. Whether you are evaluating a technology for your product, trying to understand a vendor proposal, or simply learning, this glossary is written to give you practical, accurate context — not theoretical abstractions.
