I tend to view scrum, kanban, XP and also the more traditional tools like V-model as tool boxes - or maybe some kind of pre-configured framework. They combine agile or other project management tools in order to solve problems the team or stake holders of the team have.

However, this doesn't mean you can't take out and exchange parts. Some teams work profiles fit well with set sprints with a stable set of tasks. Others, like ops work with few people, doesn't due to incalculable factors like incident management. Prioritization might need different mechanics depending on the position and the responsibilities of the team.

It's all a big grab bag of tools to create some working workflow for a team.
