Another challenge we faced was that the costumes that our dance leader ordered did not arrive even though it was express delivery. Eventually, we gave up waiting for them and tried to find similar skirts as the original one in the school drama costume office. There were red skirts that were not so similar, we had no choice but to use them. Collaboration was very important in achieving my goal as well as our team’s goal because without discussing the problems(challenges) we faced such as costume problem, we could not have made rational choices that helped us perform better. Throughout this experience, I also learnt that it is better for the members of the group to try to face the problems on the early stage of the progress than later because it is hard to fix problems at some point even when ones discover it. I would like to make suggestions to make some changes/improvement when I see errors/something missing even though it might be hard to fix that as a group.
