The scrum teams I currently work with use Planning Poker to estimate the size of user stories. This has proved to be an extremely useful activity, and we rely on it to plan work for upcoming sprints. In the past, we used special card decks for these games, which worked well when everyone was based in the same room. However, with team members now distributed across two continents, this quickly became less effective.
