Requirements management is a way of tracking what needs to be done for a project. It is kind of like a list of things that have to be done in order to complete the project. It can include making sure that the project is able to stay within the budget, keeping track of deadlines, and making sure that all the necessary tasks are completed. It can also involve keeping track of who is doing what and making sure that tasks are assigned to the right people. Basically, requirements management is all about tracking what needs to be done to make sure a project is completed on time and that all the right things are done.
