The big data thinking here can be used to coordinate thinking, that is, based on big data thinking to catch the key things. Big data is a spatial thinking, that all data should be observed and studied to coordinate, but ignored the time thinking. Therefore, the office work needs to join the time efficiency thinking, with the implementation of key things step by step to achieve the effect and efficiency. Big data thinking not based on time-efficiency considerations is a castle in the air, do not fall into the trap of the tortoise and the hare (no time dimension, all the data show that the hare can never catch up with the tortoise). Things need to be improved step by step in practice.
