Communicate effectively, and maintain efficiency are some successful organizations discussed in this article. I feel like the most important one is maintaining efficiency. I think maintaining efficiency is important because you will be busy doing your work and stay active, and if you don't start maintaining efficiency you could get behind and be pulling in the same direction.
