Agile methodologies reduce waste by cutting back on work that does not add value. Planning a project does not directly add business value. Therefore, planning at any stage of a Scrum project should be as efficient as possible.
Planning ahead for the whole project is considered waste, because Agile projects are prone to a high rate of change. Therefore, planning is done Just in Time (JIT).
