I have to write a paper that Use the seven step model provided as your base line. That means you compare and contrast other models against the one from the textbook. DO NOT discuss Methods in this paper (waterfall, rad etc...). You need to find other SDLC models, the models will be called SDLC ...some may have four steps and others may have 12 steps. The analysis is focused on understanding the common characteristics of the models (what is the same...what is different) Can you tell me what the professor is looking for?
