What stages are included in the software development lifecycle (SDLC)?

The stages included in the software development lifecycle (SDLC) provide a comprehensive framework that guides the development of software from inception to completion and beyond. The correct answer encompasses all critical stages typically involved in the SDLC.

Starting with planning, this stage involves determining the needs of the project and creating a roadmap for development. The analysis stage follows, where requirements are gathered and assessed to define what the software must achieve. Design comes next, detailing how the software will function and look—this includes architectural design as well as user interface design.

Implementation is where the actual coding takes place, translating design specifications into a functional software product. This is followed by testing, a crucial phase that ensures the software operates as intended and meets all specified requirements. After successful testing, the software moves to the deployment stage, where it is made available to users. Finally, maintenance involves ongoing support and updates to address any issues that arise post-deployment and to enhance features or accommodate changes in user needs.

This structured approach ensures that all necessary components are considered, reducing risks and enhancing the quality of the final product. Other choices offered do not cover the full breadth of the lifecycle, omitting essential stages that contribute to delivering robust software solutions.
