The scope baseline is often used for change control purposes and in making project decisions, which is why a poorly written scope will result in a large number of project changes for projects managed using a predictive life-cycle approach. Given that the project contained high ambiguity, issues may have been reduced by using an adaptive or hybrid life-cycle approach.
