The Software Development Life Cycle (SDLC) provides a structured approach for the design, development, testing, and deployment of software. It consists of various models including Waterfall, V-Model, Spiral, Agile, and Hybrid, each with distinctive characteristics, pros and cons. Understanding these models allows teams to select the right approach tailored to project requirements, ensuring efficient delivery and management throughout the software creation process.

What we have learnt
- The SDLC is a process that encompasses stages like requirement gathering, system design, implementation, testing, deployment, and maintenance.
- Different SDLC models suit different project needs, such as the Waterfall model for fixed requirements and Agile for evolving projects.
- Each SDLC model has its own advantages and disadvantages, affecting flexibility, risk handling, and overall project management.
Key Concepts
-
Term: Software Development Life Cycle (SDLC)
Definition: A structured process used to create high-quality software, defining the stages involved from conception to deployment.
-
Term: Waterfall Model
Definition: A linear model where each phase must be completed before the next begins, best for projects with well-understood requirements.
-
Term: Agile Methodology
Definition: An iterative approach focusing on collaboration and flexibility, allowing for rapid delivery and continuous feedback.
-
Term: VModel
Definition: An extension of the Waterfall model that emphasizes verification and validation with corresponding testing phases for each development stage.
-
Term: Spiral Model
Definition: A risk-driven process combining iterative development with systematic risk assessment, suited for large and complex projects.
-
Term: Hybrid Model
Definition: A combination of multiple SDLC models customized to meet specific project needs, balancing flexibility and structure.
