What are the five phases of the sdlc?

The five phases of the Software Development Life Cycle (SDLC) are: Requirements gathering, Planning, Design, Implementation, and Maintenance. These phases guide the development process from initial concept to final product delivery, ensuring a structured approach to software development. Each phase contributes to the overall success of the project by systematically managing tasks and resources.

Which stage in SDLC is a problem identified and defined?

The stage in SDLC where a problem is identified and defined is typically the requirements gathering phase. This is where stakeholders discuss and outline their needs, goals, and objectives for the project. By defining the problem in this phase, it sets the foundation for the development process to address and solve it effectively.

Iam not finding any difference between sdlc and rad please explain?

The reason why you might not find differences in the sdlc and rad is because RAD is a more sped-up version of the SDLC. RAD is typically used in small to medium size projects, while the SDLC is generally used for large projects. Another difference is that in the SDLC, one can control the scope creep of the project, whereas that is very limited when one implements RAD because you give it up for faster implementation times. In RAD you have alot of feedback from the user to refine the program more to the aspects of the user, whereas you dont get the same user input in the SDLC. This feedback loop is another reason that RAD is sometimes chosen over the SDLC
