What does a software development lifecycle (SDLC) model outline?

A software development lifecycle (SDLC) model outlines the phases of software development. It provides a structured approach to planning, creating, testing, and deploying software applications. By following an SDLC model, teams can ensure that all necessary steps are taken systematically, allowing for improved project management and quality assurance.

The phases typically include requirements gathering, design, implementation, testing, deployment, and maintenance. This structured approach helps manage complexity and enhances communication among team members and stakeholders, ultimately leading to better project outcomes. Understanding this lifecycle is critical for anyone involved in software development, as it serves as a guide throughout the entire process from conception to delivery and beyond.
