[填空题]

[A] As a science, management entails the use of organized knowledge. Many of the things managers do are a result of information obtained through formal research and study. One area in which a great deal has been done is quantitative decision making or, as it is known today, management science. We know that by using certain mathematical formulas we can control inventory and project demand more accurately than by merely using trial and error.

[B] Management is the process of getting things done through people. We know that part of this process is carried out with the development of an organization structure.

[C] Yet management is also an art. Through experience the manager develops judgment and intuition, subjective factors that are useful in evaluation situations. For example, the manager may have to choose between two strategies, A and B. All research and study may indicate that neither of the two is any better than the other.

[D] Effective manage
