SDLC 面接の質問と回答

Question: Can I build a software project without sdlc models?

Of course. There are no hard and fast requirements for a developer to implement any SDLC model for developing a software project. The ability to simplify a project into modules and ascertain the correct progression for completion is the only reason for which SDLC models and methodology was designed in the first place. You can surely work without them but the challenges will be more and there won't be any specific process to organize your work as a whole.
