Overview : Software Development Life Cycle (SDLC)

Software Development Life cycle (SDLC) is a structured process, methodology and it defines the procedure of entire software development step by step.

The goal of the SDLC is to delivers the high quality, maintainable software that meets the users requirements.

SDLC involved six phases and stage while developing any software.

  • Planning and Requirements - To plan the requirements of software that is what should it do, why it is needed. Involves collects ideas and business needs rom users or clients, defining scopes and goals.

  • Analysis - Detailed requirements are analyzed for feasibility and clarity. Understand the problems and solutions. This helps in identifying technical, operational, and financial constraints.

  • System Design - Make a plan how the software will look and work. Make the screen, databases and system flow. It acts as a blueprint for how the system will function and look.

  • Development - Write the code based on the design specifications. The Team creates features as the software planned in design.

  • Testing - Testing the developed software features an to find if any error or bugs which will be fixed and make sure it works well.

  • Deployment and Maintenance - Completed the development and testing, the software ready to use for people use or deploy. After deployment, it is improved by adding features and fixing any bugs.

More than 50 recognized models in use for SDLC. But none of them is perfect each bring various aspects and disadvantages.
Here is the top five models are
