We can see that use case driven approach is, as mentioned before, the conceptual center that can drive the entire software development lifecycle, we perform the following steps for use case driven approach that lead you all the way from analysis to design, and subsequently to development. More structured or waterfall based approaches attempt to assess the majority of risks and develop a detailed plan for the software before implementation coding begins, and avoid significant design. The plan based approach is the traditional software development methodology while scrum is a new approach that emphasizes collaboration and communication among team members during the software development process.
