The best is that Agile avoids the pitfalls of trying to make and update a conventional schedule analysis, i.e. a resource-leveled critical path analysis of a software project. By deferring task assignments to the start of each iteration, you avoid frequent replanning. In other words, Agile is a practical approach for software development projects. It fits the nature of unique and hard to predict task durations.<p>The worst is when an expediently trained "Scrum Master" with no domain expertise in coding, but equipped with a fully loaded jargon vocabulary tries to "manage" a team of coders.
