All projects must manage risk. Which of the following best describes the difference between waterfall processes and agile processes? Agile processes first identify risks and then plan for and monitor them during the project; waterfall processes are managed during each iteration. Waterfall processes plan risk responses up-front; agile processes manage risks during each iteration. Risks are identified up-front in agile processes; risks are addressed at the beginning of each phase of a project in waterfall processes. The risk register is a key document for agile processes; the developer's test register is a key document for waterfall processes
