What must member federations do to shorten a player's preparation time?

Member federations can agree among themselves to shorten a player's preparation time, reflecting the collaborative nature of governance in international basketball. This process emphasizes mutual understanding and cooperation, allowing the federations to create flexible arrangements that suit the needs of the players as well as the scheduling demands of tournaments or competitions.

This flexibility is crucial because it allows federations to adapt to various circumstances, such as a condensed tournament schedule or changes in player availability. By reaching a consensus among themselves, they can ensure that the decision is in the best interest of all parties involved without needing to involve external authorities or lengthy bureaucratic processes.

While other options may involve formalities like permission from FIBA or notifying players, they do not directly pertain to the collaborative decision-making needed to adjust a player's preparation time effectively.
