Which is a factor when deciding the duration of a management stage?

When deciding the duration of a management stage in PRINCE2®, one key factor is the work packages to be delivered during the stage. The content and complexity of these work packages can significantly influence the length of the stage, as they define the scope and volume of work to be completed before the next stage review.
