This document discusses the software development life cycle (SDLC) process. It explains that SDLC is necessary for large, multi-developer software projects to effectively communicate requirements and synchronize work. The key phases of the SDLC include planning, analysis, design, implementation, testing, and deployment. Introducing a standardized life cycle model helps divide a project into stages with clear milestones and deliverables. This approach is necessary to coordinate work across distributed development teams working on interdependent components. The SDLC provides a framework for collaborative software engineering to produce quality products.
