Erica wants the IT team to develop a solution that will allow doctors to post insurance claims online so that their customers can review see them as well. Once a claim is received, an officer will review it and send it for approval. Once the claim is approved, the company informs accounting which disburses the money to the customer. Scott as the project manager knows Erica as someone who always changes the requirements even in the middle of the projects. As a system analyst, you will have to say which development methodology is the best for this project and why is that?
